RE: [meteorite-list] Meteorite crater or crumbling of ground ?

Hello Pierre, the hole is most probably a sinkhole, created by the collaps of a cave. I think limestone is very common in the area, underlying the soil. A impact pit of this size probably wouldn't show such a sharp rim and there would be much mud thrown around. Best wishes Dennis From:

Re: [meteorite-list] impactite vs. impact glass

be brecciated by another impact event, if it is monomict, it is an impact meltbreccia, if it is polymict it is something else, maybe a lithic breccia or a regolith breccia...). Well, I hope I got it right, scientists seem to love that ;-) Best wishes Dennis Harries *NO WAR* http://www.bgs.ac.uk/SCMR

Re: [meteorite-list] impactite vs. impact glass

Dennis Harries Dear List; Is there a defined difference between impact glass and impactite? I see one picture of an impact glass that was hard to discern from impactite. So, lost as usual, is there a definition, or is it just a difference in the melt degree? Thank you, Dave Freeman
