The real question is is it found in volcanic ash/dust, which it would have to be, if it was going to contribute to the global iridium layer. Even if it weren't, I agree that the deccan traps probably represents too much of a coincidence to not have had an affect on the K-T extinction.

At the risk of terminal thread drift, here's a nifty graph I came across in researching TC's mantle model:
The red squares represent major episodes of flood basalt eruptions. The arrows represent extinction events. The sceptical question to ask at this point is whether there are many more extinction events, and the author just picked out the ones that happened to line up with flood basalts? Or are there many flood basalt eruptions and he picked out the ones that line up with extinction events? If this really is a concise record of extinctions and flood basalts, then the link between them seems unassailable. from

What ever way you cook it, it looks like volcanism is bad for our health! I never realised the correlation was so close between volcanism & extinction. I wonder how TC explains this "fluke".

-I wouldn't call it a fluke in the least, its very appealing to the model that I propose. Simply because, the 'problem' that people see in it is that its going to kill everything (or atleast lead to extinctions with different unlucky kinds). Seems, its an expectant. ------------------

quote: Why is it expected? Because it kills? The volcanism that would be expected by your model would leave nothing but very, very, lucky archaea. The volcanism that marries up with extinctions IS UNexpected by your model (message 20). How do you explain the fossil record relating to those extinctions re. volcanism? A lucky fluke? Why were ALL trilobites killed at the P-T boundary (along with 84% of ALL genera) at that time without managing to kill a single, I repeat, a SINGLE mammal, not to mention dinosaurs, but ammonites ALL died at the K-T boundary without a SINGLE primate being killed? The list goes on. Mark ps message 8 pls ------------------Occam's razor is not for shaving with.

"Why is it expected? Because it kills? The volcanism that would be expected by your model would leave nothing but very, very, lucky archaea."
--Really? So you have done the calculations? Because I have not yet, I still must find ratio's of outer-core, asthenosphere, lithosphere, and crust Lead, Uranium, and Thorium radioisotopes to even find the initial variables.

Yeahh I found it (at long last). The book is Extinction:Bad Genes or Bad Luck by David Raup. There is a discussion in chapter 10 concerning relationships between most mass extinctions and meterorite impacts. Some of the data is very similar to the data concerning volcanism w.r.t correlations.
The book is decent although not the best that I have read on the subject. I kept thinking that it was in Alveres's Book T.rex and the Crater of Doom. ------------------"Chance favors the prepared mind." L. Pasteur Taz [This message has been edited by Dr_Tazimus_maximus, 03-31-2002]

"What is a "kind", TC? Did this question of mine get answered yet?"
--Before I answer Mark's post, considering 'kinds', lets see. When you ask 'what is a kind' are you asking for a definition (in the context of the question I believe), or are you asking for what animals I can point out that are 'kinds' or how can you recognize whether something is a 'kind', a bit simmilar but different. Baraminology I believe I have heard of is attempting to do the pin-pointing with genetic simmilarity within the cooperation of speciation, mutation and differernt diversifications within hereditary characteristics on different biological levels. Though the definition of a 'kind' in another context is the group of animals that were created as is on the creation dates. --As is analogous toward an inability to give a direct definition toward 'species', the 'kind' as well is difficult to make such a direct pin-point, universal coincidence. Ie, the definition is applicable to all organisms. (Careful Tazimus, arrogance can be bliss, though It is best to keep quiet untill you have room to make such a confident assertion) ------------------ [This message has been edited by TrueCreation, 03-29-2002]
