Description

A Martian impact melt is most likely the result of a giant meteorite crashing into Mars and melting Martian target rock into a new form. That in itself is remarkable. As any type of impact melt — even in the abundant chondrite family — is highly unusual. So, here we have an exceptionally rare Martian impact melt that also displays vugs. The word vug is a geological term that describes a cavity found within a rock matrix. In terrestrial formations, vugs are a prime environment for the formation of crystals of varying types. Vugs are almost never seen in meteorites. The first known Martian meteorites were identified by the small pockets of Martian atmosphere they contained. It is likely, or possible, that the comparatively large vugs in NWA 11288 once held within them the thin and alien atmosphere of Mars! The total known find weight of this rare meteorite is a mere 407 grams.
