Wish I¹d seen this one when it came out; I¹d have gladly written a rebuttal paper. Not quite sure how they can claim there is a "complete absence of a deep Earth fingerprint", especially since they point out the low delta-C13 values in carbonadoes themselves. The same range of values is seen in r

A carbonado with fusion crust? My skepticism meter is pegged. If true it would be of extraordinary scientific interest, but the problem is that diamond doesn¹t melt. It evaporates. Silicates are content to form what is basically a liquid silicon oxide, but carbon oxides (CO, CO2) are gases, not

Whatever hit it looks (to me) like it fragmented completely when it hit the windshield. The dashboard doesn¹t have one deep gouge in it like a solid object would inflict; it has a shotgun-spray of spallation damage. Whatever hit the thing wound up as tiny pieces scattered around inside the car.

Bear in mind that you only find the big rocks when you walk a strewn field. Meteors routinely produce clouds of falling sand-grain-sized (or smaller) debris. Much of this is in the form of metallic or metal-oxide spherules ­ great radar reflectors! Cheers, MDF On 3/11/09 10:57 AM, "E.P. Grondi
