Science, Vol 302, Issue 5649, 1388-1392 , 21 November 2003Abstract:Multiple chondritic meteorite fragments have been found in two sedimentary rock samples from an end-Permian bed at Graphite Peak in Antarctica. The Ni/Fe, Co/Ni, and P/Fe ratios in metal grains; the Fe/Mg and Mn/Fe ratios in olivine and pyroxene; and the chemistry of Fe-, Ni-, P-, and S-bearing oxide in the meteorite fragments are typical of CM-type chondritic meteorites. In one sample, the meteoritic fragments are accompanied by more abundant discrete metal grains, which are also found in an end-Permian bed at Meishan, southern China. We discuss the implications of this finding for a suggested global impact event at the Permian-Triassic boundary.Excerpt from paperThe end-Permian beds are exposed over about 2 m and include the last Gondwana coal bed of end-Permian age, above a bed with the last occurrence of Glossopteris flora. Above the coal bed is a claystone breccia with anomalously low {delta}13C value (~—40 {per thousand}). Shocked quartz (8) and extraterrestrial fullerenes with trapped noble gases have been reported from this bed (9). On the basis of paleobotanic and isotopic criteria, and shocked quartz grains, the claystone breccia (Fig. 1) has been identified as the Permian-Triassic (P-T) boundary in Antarctica (7, 8, 10). This interpretation was also confirmed and extended by similar observations on P-T sections at Wybung Head, NSW, Australia (7, 10), as well as by extraterrestrial fullerene evidence from China and Japan (11).7.

OK, so far "all over the globe means Antarctica and China.

And of course you choose to ignore the obvious implications of this kind of thinking in the areas of evolutionism and the geo timeline, which the more sophisticated scientific reports only obfuscate although it is really the same kind of thinking.

That's how I read it anyway.

However, in neither case is there any way to prove that the meteorite chemicals actually are found all over the globe, as I explained.

It also gives a chemical name to the fragments which the popular accounts didn't for some reason.

In other words your more detailed scientific information has not contributed one thing new of any importance to what I've already discussed about the popular reports.

And there remains the question raised at the close of the CBS report about how these chemicals could have survived 251 million years under normal conditions of weathering.

The way evolutionism and the geo timetable are presented to the public is a disgrace, a travesty of science, and I'm as interested in blowing that kind of deceit as I am in this topic.

NOT IN THE IMMEDIATE AREA OF THE HIT, but at whatever distance the heat meets the cool of the ocean and the atmosphere, which would be determined by the size of the hit, and the water-soaked world of the FLood SHOULD, it seems to me, have some effect in reducing the expected global effect that everybody is predicting by SOME measurable degree.
