Locality type:Meteorite Fall Location
Meteorite Class:Shergottite meteorite
Meteoritical Society Class:Martian (shergottite)
Metbull:View entry in Meteoritical Bulletin Database
Origin locality:Mars
Köppen climate type:BWh : Hot deserts climate


Polished thin sections show that Dho 378 consists mainly of Maskelynite, plagioclase glass, with minor hedenbergite and ferroan clinopyroxenes (augite and pigeonite), pyrox-ferroite, fayalite, silica, titanomagnetite, ilmenite, sulfide, phosphate, and rhyolitic glass.

There is a possibilty that this glassy Martian rock will give us an opportunity to get insight into intercrustal magmatic differentiation processes on Mars.
