[meteorite-list] Block Island

Hi - 

Yeah, blueberries where they are not supposed to be if they are water products.

Generally, molten impact rock and impactor will condense into a sphere, unless deformed by atmospheric interaction, in which case you get a tektite.

As Mars' atmosphere is close to a vacuum, my guess is that there were no convecting plumes on impacts, and what atmosphere there was nearby became a vacuum. 

But that is just a guess. Elton, you have any insights into Martian hypervelocity impacts?
