Author | Topic: For whatever - your insult, and radioisotope dating | |||||||||||||||||||

Two things:
1. When the poster mentioned "lava" melting surrounding rocks (they really meant "magma"), this was a reference to false isochrons. What you need to get the poster to do is explain both why this isn't resolved with a mixing plot, and why negative slopes are so incredibly rare when they should be equally distributed. 2. You should ask the poster to evidence proper sample selection, which covers the following that *every* competent geologist (but, seemingly, few creationists) do: a homogenous sample, no obvious signs of weathering, and no obvious signs of metamorphism (especially heat). All of these things are fairly easy to detect. 3. Probably a better place to start these YECs off is to get them to address why all isotopes that aren't currently being created by natural processes on earth that have half-lives of a few tens of millions of years are absent on Earth, but ones with half lives of more than a hundred million years are still present. I.e., the "missing isotopes" problem. I've yet to see a YEC even give it a half-hearted shot. "Illuminant light, illuminate me."

quote: Ah, I was confusing your discussion of Ar-Ar with whatever's discussion of K-Ar; almost every time I've run into creationists making the mixing argument, it's in reference to false isochrons.
quote: Well, it can't hurt to try and get them to actually learn about science before they argue against it "Illuminant light, illuminate me."

quote: Please state why you are so confident that it is "proven" that C-14 forms in the atmosphere, but not "proven" in the earth. Go on, impress us with your knowledge of what is proven, and why! I'll be waiting.
quote: You haven't read a thing, have you? He won't even let people see that what he was looking at was even *wood*, let alone actually date it. How disingenuous can you get? BTW.... do you have any answers to why multiple dating methods almost always match up, why isochron slopes are almost always positive, why mixing plots would be wrong regardless of this, or anything else? In short, can you *at all* show even a *weakness* in the methodology used to date samples? Likewise, can you explain the missing isotopes? "Illuminant light, illuminate me."

You ignored the second half of the request: 'but not "proven" in the earth.'
Why is the evidence that was posted somehow less compelling than Libby's? Will you not address the latter half of my post as well, or the many unanswered questions that everyone else has been posting to you? "Illuminant light, illuminate me."

You say that you're an old-earther. Are you a young-lifer or old-lifer?

quote: And why did God make the sun appear as ancient as the Earth, from the isotopes which it contains to its stage in the main sequence, and a hundred other factors?
quote: You should. There are fossilized *footprints* buried under *many ancient basaltic flows*. Fossilized egg shells. Fossil bivalves, complete with their burrows. Fossilized plants. Soil horizons. Entire layers of deposited marine life. Etc. All underneath ancient basalt (often many layers of it). That would be quite the magic trick to get them down there.
quote: They're not fossilized. Do you not know the difference between fossilization and preservation? Also, don't you know how recent the pleistocene is? "Illuminant light, illuminate me."

quote: No, it doesn't. You clearly have no clue what isochron dating and concordia/discordia dating are, and have refused our attempts to get you to learn what they are and the significance of them. If you refuse to even learn about the topic, why are you debating about it?
quote: Argon leeching out or in would show on an isochron or a concordia/discordia plot.
quote: If it even was a fossil, of course it was mineralized - it was in triassic sandstone. Do you not understand the difference in the timescale between Pliestocene and Triassic? Pliestocene, in permafrost is unlikely to mineralize much. Triassic in sandstone is essentially guaranteed to be mineralized. What is hard for you to grasp about this concept?
quote: But only a *tiny percentage* difference. I.e., if you have a fossil that dates as 500 million years old, you can get a "little error" that will be a few million years off - but that doesn't change the fact that the fossil is "around" 500 million years old, and that almost always multiple dating methods (when done properly, and - key words here - In Cases Where It Is Expected To Not Be Unreliable (such as Snelling's case) - get the same result. Yes, I could go out and try to carbon-date, say, a clam, and get a date that is way off and say that this disproves carbon dating. But I would be attacking a straw man (in case you didn't know, you're not supposed to carbon date most marine fossils, because the ocean recycles old carbon). Snelling, too, is doing just that: attacking a straw man. There are cases where carbon dating has been tested to death, and it works every time; in these cases, it is acceptable to use. There are cases where carbon dating has been tested extensively, and it almost never works. These cases are *never acceptable* to use, except for to try and refine the method. You have yet to explain the following, despite many people asking you for it: Why, When Methods Are Done Properly, Do Dates Virtually Always Come Back As Concordant With Completely Different Methods?
quote: LAF!!! Pray tell, what is causing C-14 to leach out of Pliestocene fossils at a different rate than C-12?
quote: You know, carbon dating is hardly the only thing that confirms this.
quote: ... which makes it ideal for recent fossils, but worthless for ancient ones...
quote: Because They Were Encased In Ice, And From The Pliestocene! And They Were Not Found In Flood Sediments "Illuminant light, illuminate me." [This message has been edited by Rei, 01-06-2004]

quote: First off, bodies don't just "poof into stars". The initial phase of energy release - gravitational collapse - provides plenty of radiative energy, and lasts for several million years. Then you start to get deuterium fusion in addition to the gravitational energy release. Deuterium fusion is what powers brown dwarfs; it is fairly weak. However, if gravitational collapse continues long enough, you get the first bit of regular hydrogen fusion. Over the next several hundred thousand years, the star progresses into becoming a main-sequence star as the fusing core expands and the convection belts establish themselves. Note that the star is releasing *tons* of light energy well before *any* fusion ever starts. Our star is currently halfway into the main sequence. If you had visited the Young Star thread as you were referred to earlier in this debate, you would have known this. "Illuminant light, illuminate me."

whatever didn't specify K-Ar; seing as (s)he only mentioned Ar, I assumed Ar-Ar; although, you are still correct - Ar-Ar is suitable for isochron, but not concordia/discordia.

If this was from a volcanic eruption that cooled underwater, where is the evidence of pillowing?

quote: Once again, I have to ask you to define "became a star", since there is no moment when a star is born, it's a process stretched over millions of years. Furthermore, our sun shows all evidence of being a main sequence star about halfway through its fuel which would occur for a star like our sun at 4 1/2 billion years.

quote: Unfortunately, there is a kind of massive overland flood, and it doesn't care canyons - it smooths out regions. It *flattens* land, leaving a rippled terrain somewhat similar to glaciation. The same thing has happened many places on earth, including here in North America (the Missoula floods, which flattened parts of Montana, Idaho, Washington, and Oregon). Canyons are caused by water moving in a *small* area, not a large area. Furthermore, if you think that the Grand Canyon was carved by the flood, you have to think that it was both deposited *and* carved by the flood, since it contains fossils - even fossilized *footprints* that I suppose were somehow layed down in tact by your flood.
quote: And...? We see species distributions changing *in our own lifetimes*. What's your explanation for them only growing here now?
quote: That statement is just false. There are two things required to form a fossil: Preservation, and fossilization. Preservation can occur in numerous different ways, from ice to being buried in mud to living in a relatively non-corrosive environment. If an organism is suitably preserved, fossilization is quite likely.
quote: Not in landslides, mudslides, glaciation, volcanism, and a host of other events, both local and regional. You really haven't thought this through, have you?
quote: Floods leave utterly different layers. Floods do not lay down strata and rapidly alter their content. They do not sort fossils based on radioisotope content and lineages. They do not lay down water-soluable minerals. They do not preserve footprints. They are very distinct, and we've seen many types of floods (from huge overland flooding to seasonal river flooding and more); they're not even remotely close.
quote: No, the biblical flood was the answer until scientists started looking at the rocks and the fossils, and were unable to explain it. However, they *still* refused to give up the creation-concept, and instead had to switch to the "multiple creations" theory, which was that God created and destroyed the world several times. They had to keep adding more and more "creation/destruction" pairs in, until they finally gave up on it. It just doesn't work out; the fossil layers are too consistantly sorted.
quote: Floods do not alter mineral content every couple milliseconds, nor are they good for laying down sheets of basalt.
[quote]local catastrophies like mt st helens also contributed to local burials,quote: Coming from one who hasn't even read about isochron and concordia discordia, and thus doesn't know what their assumptions are, this line is quite amusing.
quote: Ah. That's why the Nature article just threw away their error, right? Get a mit and catch a clue: Science Never Throws Away Figures That Don't Fit. Got it? I know that you, in your conspiratorial way probably don't believe it, but you're free to ignore reality all you want. When there's figures that don't fit, science's response is to *debate over them* and try and figure out what's wrong. When the results still don't fit, it leads to the revolutionizing of theories; this has happened many times, such as when Newton's laws were found to fail on the fringes and relativity was forced to enter the scene. You think people *wanted* to believe that there was an absolute speed in the universe, for example?
quote: It would pillow. See the related thread about basalt and pillowing.
quote: In what manner?
quote: Few believe that the diamonds *absorbed* argon. Such a thing has never been shown to be even close to possible - and we've subjected diamonds to all sorts of bizarre conditions, as synthesizing them is a very important industry. Consequently, the diamonds had to have been formed either with the small error producing, rare exceptional case compared to all diamonds in existance that have been studied, where the rest match up, amount of argon, or of an imbalance of an isotope which decays to argon.
quote: We can tell when water has reached an area - since his fossil was hematite, that *requires* water. Likewise, in most cases, we can tell that there *wasn't* water there, by what water hasn't damaged or formed. You're talking about some sort of water that can sneak in and out without changing anything except carbon isotope levels, which is a ridiculous proposition. How would you suggest that happen?
quote: No. They rely on the fact that multiple independent methods of dating continue to keep producing incredibly close ages for everything that they test, and with the incredibly rare exceptions (which warrant their own articles in Nature, as you noticed, out of all of the dating done every year which is usually just listed as part of another study), something that you have *yet* to explain. Please, Please, Please, for the love of God, answer all of the questions you've been posed! "Illuminant light, illuminate me."

quote: Actually, your post makes precisely clear what the problem is: You don't know even a lick of chemistry, do you?
quote: Argon is not a compound, it is an element. Being a noble gas, it is almost impossible for argon to bond to anything else. It's an inherent property of noble gasses; their outermost electron shell is completely filled. It is possible, but *extremely difficult*, to create noble gas compounds (it wasn't even achieved until the 1960s). The resulting end products that they managed to create were *incredibly* unstable. The compounds that I'm aware of are xenon-based; it may be possible with argon as well, but it will be even more unstable. For all practical purposes, noble gasses do not bond.
quote: You've got it all wrong: first off, your line of "reasoning" only applies to K/Ar dating (not Ar/Ar which is isochron and not subject to most cases of leaking).
quote: It's Not Circular When Multiple Independent Methods Return The Same Result, something that you keep refusing to address!!!
quote: The article discussed in the link refers to molecules of CUO *trapped inside solid noble gas matrices* that interact weakly with the matrix. I.e., they're not even stable enough to hold themselves together - and this is *at temperatures near absolute zero*. How exactly are you proposing that we get such frigid solid noble gas matrices in the earth?
quote: You believe that individual CUO molecules are trapped inside noble gas matrices in basalt? Please tell me that's not the case Just to reiterate the point: In The Experiments That You're Referencing, Solid Argon Is Trapping CUO, Not The Other Way Around, And The Temperatures Are Near Absolute Zero.
