Hi Chris and List, I read somewhere that some scientists think the Chicxulub impactor was a carbonaceous chondrite. I don't recall what their evidence was to support this, but if it's true, such an impactor wouldn't have survived for very long - especially in a cataclysmic event because the after-effects are so intense and devastating. I would imagine that the same would hold true for any large ancient crater like Chicxulub, Sudbury, or Vredefort. The best we can hope for is some kind of remnant impactite, shattercone, etc.
Here is a list, sorted by name, of the known impact craters - http://www.unb.ca/passc/ImpactDatabase/CINameSort2.htm I have photos of several impactites from these structures that are shown in my EoM collection here - http://www.encyclopedia-of-meteorites.com/collection.aspx?id=1564 Best regards, MikeG On 7/24/10, Chris Spratt <[email protected]> wrote: > Of the 4 I mentioned which have meteorites associated with them.
