Re: If the ARK was real here is what we must see.
Which way do you want the water travelling - inland, or away from the landmass ?
It depends on the location. Generally water was coming from the glaciation in the south of Pangea. Some of the water would have been a pure marine incursion just due to rising sea levels, but large amounts of this water would be cold glacial water mixed with marine water flowing north across the continent directly from southern Pangea.

Re: If the ARK was real here is what we must see.
How are you reconciling "MARINE INCURSION" with "water flowing outwards from the landmass" ?
Initially the strongest flows are outward in Southern Pangea. But according to the bible the water settles for 150 days after the mountaintops are covered. Its during this 150 day period when the entire earth is covered, that the earth its now an ocean. You cannot refer to a worldwide unbroken sequence of water as a lake, it is by definition the ocean. Marine. Even if the top layer is a bit colder and fresher and less saline than the rest of the ocean, this is still marine.
In some northern areas there could very well have been water rushing in from the oceans, but after months of flows outwards, its not an essential part of the process that marine bodies would still be floating and be washed into these areas. The general flows would have been from Pangea outward into the vastness of the Panthalassic Ocean.

Re: Geology is irrelevant; try addressing the topic.
None of which has anything to do with dates of 65k-130k. My point is that without even getting into anything regarding the mechanics of dating we can see that you just made that stuff up. Nothing you've mentioned regarding dating is the least bit helpful in that regard.
I get those dates from the list of sites for early humans that I quoted earlier in this thread from Wikipedia. These sites have been dated to 130 000 ya and younger, and show the first signs of humans around the Arabia/Levant/Egypt/Ethiopia area. This is earlier than reliable carbon dating, and not early enough for radiometric dating and so these sites are dated according to evolutionary assumption. (the assumed advancement of mankind over time). These dates can be vastly out, because its entirely possible that explorers and hunter gatherers left a fledgling Sumerian civilization and entered into a less advanced lifestyle across the planet.
Are you seriously claiming to have done this kind of study already? Can you honestly do any kind of dating beyond historical references without making some assumption about the rate of some process.
I have looked into it. You compare the amount of sedimentation currently going into the gulf of Mexico with the amount of sediment that exists along the entire valley and you can come up with some interesting figures which make the slow process of evolutionary assumptions impossible.
Unless it gets the pyramids built sometime after the flood, revising those dates may help with other parts of genesis, but as far as proving a flood date, Rohl's dates (which don't constitute a dating system) are just rearranging deck chairs on the titanic. They don't help you correct C-14 dating in any significant way.
I was referring to various dating methods, not just carbon dating.

Re: If the ARK was real here is what we must see.
I did a bit of twiddling around on google, and it is reckoned that if all of the ice in Antarctica melted, it would raise sea levels by 61 metres, which as I recall is consistent with your odd view that mountains were actually only baby hills, back in the day. So let's run with a melting of ice from Southern Pangea of an amount roughly equal to the amount of ice in Antarctica.
It's estimated that there are 27 million billion tons of ice in Antarctica, with an average temperature of -35 degrees Celsius. I think it's reasonable to assume a reasonably similar quantity and temperature of ice, to allow reasonably sufficient flows for your scenario.
Now, bearing in mind that you can't use marine water to melt the ice (marine water does a fair job of melting ice, but it would ruin your "no marine water" scenario), would you like to hazard a guess as to how much the air temperature would have to rise on earth, in order to melt 27 million billion tons of ice, with a temperature of -35 degrees, in a period of 40 days ?
I don't know the answer myself - I suspect the maths might be complicated - but my guess is that Noah and co would have needed air con.
And the ice-caps of Pangea were far more vast than Antartica which contributes towards your point. Good thinking there. I would assume that the warm marine water would contribute towards the melting of the ice caps, but its possible that the hot air and warm volcanic rainfalls did most of the job. Most terrestrial and marine sedimentation across the planet show a clay layer with signs of volcanic dust, and so the Siberian Traps had a vast effect on the planet at that time. I agree the scenario isn't simple. Nevertheless I don't see a mechanism that would deposit significant marine fossils into the inner regions of Pangea when generally the flow is outward towards the Panthalassic Ocean.

Re: The flood story (getting pretty off the topic core)
The only reason to even suppose that Noah's descendants lived in Turkey is because the Bible mentions Mt Ararat.
If you're not referring to Mt Ararat, then any mention of Turkey is completely arbitrary
True. The bible mentions the hills/mountains of Ararat or the hills of Armenia.
And it didn't exist at the the time. And the site was also underwater
True Ararat did not exist at the time the ark landed, however it did exist when the bible was written, and this is why they could use that huge mountain as an easy reference point for where the ark had landed.
That you freely admit to a fallacy is just too funny.
Haha hope you had a good laugh. Thanks for the definition of cherry picking. By the act of admitting to it I was ironically not cherry picking. My point was to illustrate how open the bible is to interpretation.
Armenia wasn't even attached to Turkey during the Triassic. It's on the Eurasian Plate, which was on the other side of the Paleo-Tethys Ocean.
I thought you said that region was completely inhospitable to human life?
Ancient Armenia was more vast than modern Armenia, and its centre point was south west of Ararat, much of Armenia overlapped the Arabian plate at that time.
Well gee, I dunno... maybe because Noah's landing site was underwater at the time. Just a minor detail. But don't worry, it's only the Bible. I mean, what the heck gives God the right to question your version of events, amiright?
I am not accusing you of deliberate cherry picking, but if you research this further you will see that many maps show most of the Arabian Plate above water during the cretaceous.
File:100 global.png - Wikipedia
The eastern portions were sometimes submerged judging by the source of cretaceous oil. I think we need further discussion on the source for your information and map. History does show widespread flooding across Sumerian cities which could reveal a transgression in the area, although the flooding is currently attributed to rivers.

Re: The flood story (getting pretty off the topic core)
This is a flimsy excuse and a blatant device for you to demand evidence from others whilst not providing any evidence of your own
I am participating on this thread because of blatant exaggerations that I saw on the first page, that were going largely unchallenged. I have since questioned other sweeping claims made. That's the terms of reference.
Evidence? No, of course not. It's hard to find evidence for things that you make up as you go along.
Insects dominated the lower latitudes.
Totally false.
I admit I haven't got evidence for birds in the paleozoic, I anticipate they will be found in a high latitude high altitude biome. (the Siberian plateau).
Regarding insects, I meant that insects dominated the environmental niche currently filled by birds. They were the large flying creatures of the main regions of the paleozoic.
Well then, you managed to misrepresent it without trying.
You cited a study that tentatively suggested that there might have been angiosperms in the late Permian. You went on to claim that this was evidence of "modern biomes". It is not.
Even if these ancient angiosperms are real, it does nothing for your case. You still need to show completely modern flowering and fruiting trees going back to the earliest life. You cannot show that.
It certainly helps my case that there is supporting evidence for angiosperms (eg flowers and fruit trees) in the paleozoic. I agree it proves nothing.
And I showed you the multitude of mines and boreholes that penetrate that basalt. The idea that it presents some kind of impassible barrier is your fantasy. If you are having trouble distinguishing your fever dreams from reality, you may wish to consult this helpful diagram;
Its possible to find cities by digging a mine, but its not a likely scenario. Looking at the bible's indication of the pre-flood period (~2000 years) and pre-flood population growth rate the world's population wasn't that great at the time of the flood. To find a deeply buried city or even a skeleton in the vastness of Siberia is not an easy task solved by digging a number of mines.
If you can't show us where the pre-Flood humans are then you have no business suggesting that they existed. Scientific conclusions follow evidence. You have no evidence of humans before, during or after the PTB, not for 250 million years. The honest thing for you to do would be to either find that evidence or keep your fantasies to yourself.
I admit that from a scientific perspective, my speculation that there is an ancient civilization locked away under the Siberian basalt does not contribute much, but is consistent with my stance that a pre-flood civilization is not currently disproven. You may apply skepticism however I freely admit my view is faith-based, and cannot at this stage be scientifically proved (or disproved).
Utter rubbish. The Bible has humans around from day 6. Do you really believe that they were hiding under the Siberian traps for all that time? It's ludicrous. Can really you not see how tissue-thin an excuse this is?
I never said they were hiding under the Traps I believe the volcanic activity caused their destruction and buried them under kilometers of lava. This northern latitude ancient civilization is consistent with ancient Indian stories on the origin of man.
What a lot of waffle.
Your theory demands that all life be wiped out at the PTB. This is not what the geological record shows. An honest enquirer would, at this point, shrug and say "Oh well, I guess I was wrong!". But not you. You continue to make up silly excuses for why you are right and reality is wrong. It really is a pathetic spectacle.
Its your strawman that requires all life be destroyed. The actual wording of the bible merely requires terrestrial life be completely destroyed, and does not restrict its recovery to the ark. Its possible some life recovered from coastal marine bottom feeders that survived the flooding by swimming (lystrosaurus) , and its possible that plants survived from surviving seeds. The rest survived from the Middle Eastern ark.

Re: Uniformity assumptions...
I doubt you can do what you claim.
Do you really believe that the a current fast rate of deposition makes a past slower rate of deposition under different conditions impossible? Which is more likely to be constant over time, a rate of deposition of sediment anywhere in the world in various conditions of water flow and geography, or the decay rate of potassium 40?
Sedimentation should not change by a factor of thousands. Sedimentation would have to be about 50 000 times slower during the Mesozoic to explain fossilisation along the Mississippi. The Mississippi deposits about 200 billion kgs of sediment annually. I hope the links do work:
A model of the effects of sedimentation rate on the stability of Mississippi Delta sediments | SpringerLink
A model of the effects of sedimentation rate on the stability of Mississippi Delta sediments | SpringerLink
This amounts to more than 15cm per year over the entire Mississippi marine delta region. (200 000 km2?) This is enough sedimentation to produce the entire Mesozoic and Cenozoic fossil record along the Mississippi river in 4500 years.
I have a Muon theory. Muons produce many neutrons, neutrons slow down decay. Muons are vulnerable to the magnetic field and during periods of a strong magnetic field radiometric decay would have been faster. I believe there could be more chance of major fluctuations in the decay rate of Potassium than in the rate of sedimentation.

Re: If the ARK was real here is what we must see.
I'll save you the bother. Here is the only thing you've found to back up that particular mistaken belief;
quote:
"The two cycles accord with the sequence in the Meishan area, i.e., the Changxingian transgression after Longtanian uplift, followed successively by a late Changxingian regression, the end-Permian-earliest Triassic transgression, and the late Early Triassic regression[29]. Comparison with similar sequences over the whole Yangtze Platform[30] shows that the sequence stratigraphy at Chahe is correlative with that in the whole of South China"
This quote simply does not say that any transgression covered the whole of South China. It mentions a transgression in the late Permian (Changxiangian), followed by a a regression (Changxiangian again), then another transgression at the PTB, then another regression in the Triassic. In none of these examples does it mention the extent of any of these events.
You have no basis upon which to suppose that any of these events represents a total flood, any more than you can suppose that the regressions mentioned left all the land exposed.
The thing you seem to have picked up on is the word "correlated". You seem to think that this word means that the authors are saying that Chahe had a marine incursion. That's not right. They're just saying that all of their observations of the geology in this area can be correlated into an overall picture of events. They're not saying that all those events were marine incursions.
You have simply misunderstood this extract, taking it out of context. Your stubbornness about this is unfortunate.
If everywhere you look in the region, you see the same cycle of transgressions and regressions, this means that they exist everywhere you look.
"shows that the sequence stratigraphy at Chahe is correlative with that in the whole of South China"
Sure, there could have been one spot or an entire region that does not contain that transgression in South China. That is what I have asked you to show, but you have not shown it. In the meantime "the sequence stratigraphy at Chahe is correlative with that in the whole of South China."
This means the same sequence of transgressions were found across the area.
The Flood can't include much in the way of Permian layers if you're going to insist upon calling the Siberian Traps event the "fountains of the deep". That has to happen at the beginning of the flood to remain in accord with the Bible story.
Further, the Kayitou formation does have marine layers, but at the earliest Triassic it is non-marine, so that is just as bad for your argument as the Xuanwei.
I do believe radiometric dating is a loose reflection on relative dates but my timeframes are extremely compressed during the PT boundary. This is due to the magnetic field reversing during that time, slowing down radiometric decay to slower levels even than today. Thus I would associate the 255/260 million ya volcanism (Emeishan Traps) with the beginnings of the volcanic induced rainfall of the flood. Obviously stratigraphy is an accurate reflection of relative dates. Late Permian layers that reflect disarticulated fossils, and reducing numbers of Permian markers along with increased clastic rocks showing increased fluvial flows would in my view reflect the initial volcanic induced rainfalls, escalating toward the Permian Traps in which they peaked. The volcanic ash would be most detectable during the volcanic peaks. (Emeishan then Siberian).

Re: Uniformity assumptions...
Well you theory is wrong. Muons decay in to neutrinos not neutrons specificity 2 neutrinos and one electron. About 65 billion neutrinos pass trough every square centimetre of the earth every SECOND. Damm its a wonder we even get our nuclear reactors running if they slow down the decay rate. O yes, they don't.
Oh and we use NEUTRONS to start nuclear decay in reactors we fire them at uranium -235 that causes that particular atom to decay and release more neutrons that hit other atoms cause them to decay and release more neutrons ......
Some people do want to associate neutrinos with changes to decay rates, but I agree with you they have no effect. I never mentioned neutrinos, I'm referring specifically to neutrons.
With specifically heavy isotopes, neutrons can maintain their instability through neutron capture. ie the unstable parent isotope through the capture of neutrons cannot decay into the daughter isotope until the neutron bombardment stops.
Muons give us energetic neutrons through fusion. They also generate neutrons in other ways as well.
http://www.starscientific.com.au/muon-catalysed-fusion/
"Because the orbit of the heavier muon is much closer, it causes the atoms in the molecule to draw closer until the natural repelling force is overcome and a strong nuclear force brings the atoms together — causing them to fuse. This process kicks the muon out to do its job all over again some 300 times. This fusion gives us energetic neutrons"

Re: If the ARK was real here is what we must see.
I would love to hear your detailed analysis of the mechanism behind this. How does a magnetic reversal affect the dating exactly?
Besides, your timing is out. If the Flood is 4500 years ago, with an apparent age of 252 000 000 years ago, then we get a measure of about 56 000 apparent geological years per mindspawn year. The longest your Flood can cover in the geological record is about 56 000 years
My "Mindspawn years" are not on an even scale with mainstream years. They fluctuate according to the strength of the magnetic field. There was a magnetic reversal during the PT boundary and so I believe there has been extreme extension of that particular period (my timeframe is extremely compressed during the PT boundary).
If you want to fantasise that this marine incursion would have had no marine life, you need to explain why it differs from every other marine incursion. This is another example of you making sad little excuses for missing evidence.
For 3 reasons there would be less marine life during a rapid worldwide flood at the PT boundary:
1) It was a sudden and rapid flood followed by a rapid regression. (not enough time for new ecosystems to develop)
2) There were general outflows away from continents until the water settled (glaciation melting)
3) During the initial stages of the flood, the sea close to the submerged continents would have consisted of very cold freshwater from the melt, a unique environment unsuited to the slightly warmer saline lifeforms of the ocean.
Not all of them though. There are still plenty of PTB sequences with marine fossils. There's no reason to imagine that any PTB marine section would be devoid of life.
Vimesy also makes an excellent point; if you think that these events killed off a lot of the existing life, then we should see their fossils. We don't.
Yes some marine life survived. However most marine life became extinct during the PT boundary.
And we do see their fossils. Permian fossils both marine and terrestrial that never survived the PT boundary and numerous.
You just keep digging don't you.
It doesn't matter whether the lakes in question were freshwater or saline, they were still lakes. Lakes are not found under the sea. A lake under the sea would not be a lake. It would just be more sea.
Similarly, we do find rivers at the bottom of the sea. A river at the bottom of the sea would just be more sea.
As it happens, we know that the lakes in question (those in the Xuanwei formation) were freshwater because they are full of freshwater plants. Ferns don't grow in salt water.
Rivers and lakes are terrestrial features. Your repeated refusal to face this reality is making look like a fool.
The geologists themselves relate the lacustrine environment to the transgression. And please post your evidence that the "lakes in question" are full of freshwater plants.
http://www.geobiology.net.cn/...-28/20120928090186978697.pdf
"In the P-T transitional beds (Beds 56―80), the change from meandering fluvial at the top of Xuanwei Fm. to lacustrine in the lowest Kayitou Fm. reflects a deepening and transgressive process "
The change from meandering fluvial to lacustrine reflects a deepening and transgressive process.
Please read those words carefully. Its the "lake-like" lacustrine conditions that reflect the sea coming into the land (transgression).
The very thing you say points away from a transgression, points to a transgression. But I already posted this, so it seems I'm wasting my time with you and your commitment to reading and understanding the links that I post.
Well, I know that "lacustrine" is not a synonym for "marine". And I know that simply saying "Look! A transgression!" does nothing to tell us the extent of the transgression.
I never claimed I could prove a worldwide transgression. I asked you to find somewhere where there isn't one. I'm still waiting. You seem to be distracted by semantics , focussing on words like "terrestrial" and "lacustrine" instead of really getting into what those geologists actually mean.
Since when is "pillock" a swear word? Frankly, "pillock" is the most flattering term I could find for someone who repeatedly insists that a lacustrine environment represents a marine incursion. To be any more complimentary about such incredible foolishness would seem perverse.
I never said pillock was a swearword. You were saying that I was "inviting" swearing, I was just saying I'm also tempted to swear but I refrain, and hoping you also refrain.

Re: Uniformity assumptions...
Reference required. And calculations of the amount of neutron flux and it's effect on all relevant radioactive isotopes.
Don't ignore (as you of course have) the fact that radioactive decay is an umbrella term for three very different processes, each of which has variations. Yet the vast majority of radiometric dates based on different isotopes agree. Therefore any effect you propose must affect all relevant radioactive isotopes equally. Think especially of 87Rb which decays by electron capture.
I do not know enough about the process to state the extent of the effect. Or the maths behind it. All I have at this stage is a likely mechanism that would logically effect the rate of decay.
This process would affect all those processes in which heavy isotopes decay into daughter isotopes. And it would affect all processes that are calibrated against those original processes.
Regarding Rubidium, I'm not a YEC, and have no problem with an old earth. Its more the 0- 600 million ya period that I dispute, I believe it represents a 0-6500 ya period.

Re: Uniformity assumptions...
Again, all that even if true is once and yet again totally irrelevant to the topic and just another example of your admitted ignorance and also an attempt to misdirect peoples attention from your total failure to address the question.
It is also totally refuted by the evidence of Oklo fission reactors. There we can compare the decayed products to what we see today and guess what? There is no difference. They are what is expected from 235U.
So here is where we stand.
If any of the Biblical Flood myth stories were true we MUST see a bottleneck event signature dating to 4500 years ago in EVERY critter descended from the critters on the Ark.
Such a signature does not exist in any critter yet examined.
Since that includes critters specifically listed as being on the Ark, the Biblical Flood myths have been refuted.
Sorry Jack but it really is that simple
Under compressed dating scales, you actually do see that bottleneck signature in some mammals. I am still waiting for you to show me some mammals that do not have the bottleneck signature. You keep making the claim, and keep failing to support your sweeping statements.

Re: Paleogeography of North America
There was no worldwide flood at the Permian Triassic Boundary.
Paleogeographic maps of the last 550 million years can be found here:
http://www2.nau.edu/rcb7/nam.html
Only the latest studies are moving towards this general acknowledgment of a major transgression at the PT boundary. Before that a lowstand was always assumed at the PT boundary. I already posted links that show this transition of thought from a lowstand to a major transgression at the boundary. When you actually look at each location, you do see the flooding. Either there are definite signs of a transgression, or a regression causing uncomformities (many layers missing), or we see geological features that can easily be interpreted as flooding, even if an alternative geological explanation does exist.
To support your maps, could you please present me with a location that shows no possible signs of flooding around the PT boundary. Granny Magda has attempted to do so, and has focussed on the Xuanwei Formation, yet above this formation in the Xuanwei region a transgression is acknowledged by geologists. ie the terrestrial sequence is broken by a brief transgression.

Re: The geologic meaning of words
Hi Granny Magda,
Maybe this will help, maybe it won't.
Mindspawn appears to be using the standard English definition of the word correlate which is (intrans) "have a mutual relationship or connection, in which one thing affects or depends on another".
This is not how the word is used in a geologic context, which I think you know, but can't get across to Mindspawn.
From the Glossary of Geology5th ed. AGI) correlate v. To show correspondence in character and stratigraphic position between such geologic phenomena as formations or fossil faunas of two or more separated areas. adj. Belonging to the same stratigraphic position or level.
You see the marine PTB sequence and terrigenous PTB sequence in China CORRELATE to the Park Salt in the Williston Basin of Montana, North Dakota and South Dakota. This up to 300 foot thick evaporate salt deposit formed at the same time as the PTB formations in China.
It's rather hard to get an evaporate deposit at the same time the world is supposed to be totally flooded.
You might mention to mindspawn that a lake is a body of water surrounded by land. The lacustrine deposition and sediments in Lake Erie today are clearly the result of the fact NY, PA, Ohio, IN, ILL, and Ontario are above water and supply the sediments for the lacustrine deposition.
I don't think this will work with Mindspawn. That's my opinion as someone who spent the last 37 years working as a petroleum geologist. Sometimes you need to realize the person you are talking to is not stupid or stubborn, they just don't have the background to understand what you are explaining.
Thanks for your input into the discussion. Could you kindly read the following link, and the context of this quoted comment:
http://www.geobiology.net.cn/...-28/20120928090186978697.pdf
"The two cycles accord with the sequence in the Meishan area, i.e., the Changxingian transgression after Longtanian uplift, followed successively by a late Changxingian regression, the end-Permian-earliest Triassic transgression, and the late Early Triassic regression[29]. Comparison with similar sequences over the whole Yangtze Platform[30] shows that the sequence stratigraphy at Chahe is correlative with that in the whole of South China"
The definition of the word correlate, seems to have a very similar meaning in geology, as you quoted: "To show correspondence in character and stratigraphic position between such geologic phenomena as formations or fossil faunas of two or more separated areas".
Other than that particular quote, the following links also indicate a transgression over the Yangtze platform:
http://palaios.sepmonline.org/content/23/6/356.short
http://work.geobiology.cn/...IASSIC%20IN%20SOUTH%20CHINA.pdf
"by the terminal Permian, another transgression began in South China, in other words the global Triassic transgressive sequence began below the Permo-Triassic boundary in South China"
Regarding a general transgression, the original article which I quoted argues for a transgression at the PT boundary as opposed to the previous view of a lowstand. Its possible your maps are based on the earlier view of a lowstand, not the later view of a strong transgression.
http://studentresearch.wcp.muohio.edu/...inctionsealevel.pdf
http://www.largeigneousprovinces.org/...t/files/Emeishan.pdf
"The uplift probably ended in the beginning of the Late Permian (∼258 Ma) because a new transgression and depositional onlap started at that time"
http://www.sciencedirect.com/...rticle/pii/S1367912013002101
"the denudation product from the weathering of the parent rock was migrated to the sea-continental margin at the continent side carrying huge quantities of REE with it and was preserved by the QUICK MARINE TRANSGRESSION"
Regarding the word "lacustrine", the writers of the following article associate "lacustrine" in the lowest Kayitou (early Triassic) with a transgressive process. Maybe you can enlighten me why they would associate lacustrine conditions with a transgressive process:
http://www.geobiology.net.cn/...-28/20120928090186978697.pdf
"In the P-T transitional beds (Beds 56―80), the change from meandering fluvial at the top of Xuanwei Fm. to lacustrine in the lowest Kayitou Fm. reflects a deepening and transgressive process "
Regarding specifically China, the important questions are:
1) Was there a widespread transgression in South China at the PT boundary. I believe I have shown enough evidence of this.
2) Around the PT boundary, is there any spot in South China where flooding is unlikely when considering the geologic phenomena?
