Age Correlations and An Old Earth, Version 2 No 1

Sure. Let's base it on a "different nature" that we don't know anything about and has no evidence to support it.There. That's a lot better.Now it can be based on whatever you want time to be based on, and you can change it whenever you want. The best of all worlds, ... er ... natures...I dare say that this strikes most people as kind of funny, or maybe pathetic. You really have nothing.

Nice link.I thought it was interesting that the upper limit for DNA preservation is as much at 1.5ma. More importantly, that limit was for 'contemporary sequencing technology'. Is this telling us that fragmentary DNA might linger for a longer period of time? Or that technology may push the limit back even further?

Ummmmmmm, nooo ....If this is your understanding of dendrochronology, it's back to high school for you. Edited by edge, : No reason given.

Did you really just write this?This is just a ludicrous, hypocritical demand that makes mainstream YEC look almost sane.

If iridium were derived from terrestrial sources (meaning earth itself), the pattern of iridium distribution would be more local and spotty. And, in fact we do see that pattern at places like Sudbury or the Bushveld complex and other locations. Those are places where we have more deep-sourced magmas, but AFAIK, there is nothing thought to be emanating from the core.On the other hand, the K-T deposit is contemporaneous and global in extent. probably derived from the pulverization and vaporization of an extraterrestrial object. My understanding is that there are other, less well-known iridium layers on the planet.Here is an interesting comparison: We don't know the Ir composition of the core, but there is a suggestion that it is much higher and possibly comparable to asteroids.

Not likely. Impact sites have been studied in detail for decades now.Furthermore, we have no evidence for 'fountains of the deep' anywhere in the world. Perhaps you could describe what one would look like? If they existed, maybe, but igneous events usually do not give us a global pattern. Yes, many times. Here is a general discussion from Wikipedia with my bolding for emphasis. I'm not sure what 'the stuff' is in this case. Certainly an impact can result in igneous events, several of these are known. But they are distinctive, such as the one at Sudbury, ON; and do not produce global igneous or sedimentary deposits. We do not find granite in the core, nor in the mantle. Granite is mostly confined to the continental crust.

No, we see phreatic (water driven) eruptions all the time in the geological record. They do no produce impact features. No such deposits are known. Such an event would have an obvious volcanic connection that is not in evidence.If you know of such a location or event, please enlighten us.

So water came from the core of the earth?Please document this.

Well, there's also a lot more than reflection seismology to solid earth geophysics. The field of geophysics is very much involved with the composition and properties of all parts of the earth including the core, solid and liquid. When we take into account all of the data, including magnetics, gravity measurement, global seismology and even (to some degree) some surface geology, there's quite a bit we can say about the internal structure of the earth.For instance, we know that iridium is the second most dense natural element on earth and it would logically partition into the core of the earth during early stages of planet formation along with iron (which is instrumental in forming our magnetic field) and other heavy elements. The trend of increasing iridium content with depth in the earth suggests much higher concentrations in the core also.However, we have no volcanism other than some isolated (not global) magmatic occurrences, that are probably not directly related to the core. This is what Pressie is telling us in an earlier post. Sure, there are iridium anomalies but they are nothing like the global K-Pg layer.Furthermore there is no association between geohydrothermal systems and iridium content on a global basis. After all, why would there be water in the core of the earth to transport iridium to the surface in the first place?With all that we know, an extraterrestrial source is by far the best explanation for the K-Pg layer. Of course, that makes no difference to our "alternate states" YECist. He would rather base his theory on what he does not know rather than what science has actually learned. In my opinion this is all some kind of negative science or sorcery that has become popular with the poorly educated. Edited by edge, : No reason given.

In my opinion, we cannot compare modern or even geological mid-ocean ridge vents with the purported 'fountains of the deep'.The only comparison is that they are underwater springs (I guess).Other than that, I don't see any comparison with a hydrothermal vent that would eject water and rocks all over the solar system.

Exactly. The only caveat is that, even in the K-Pg layer, I understand that the iridium is finely divided in up to 4 very thin laminations in some locations. This is almost certainly due to reworking of a blanket of ash during several seasonal or storm events. Same thing happens with modern volcanic ash deposits.ABE: This latter fact is something that YECists will try to utilize against the impact hypothesis.Also, I keep in mind that there were a lot of things going on at about that time in geological history including impacts. The actual extinction 'event' may have a number of causes. Edited by edge, : No reason given.Edited by edge, : No reason given.

As long as it's in the context of differences, fine.But for instance, your argument about a multiplicity of ages blowing up the FOD/flood relationship is countered by Faith's argument that "Well, everything happened in one year", so they're all the same age anyway.Hmmm, am I starting to think like a YEC??

Details, details ...

Actually, science only deals with reality. So, yah, it's kinda hard to know what your mind can contrive.Show us a 'fountain of the deep'. And you know all about it?Heh, heh ...

Yep, but no evidence that it was erupted into a global sedimentary deposit.Sorry.
