Ureilites

The ureilites are named for Novo Urei, a rural village in the Mordova Republic, Russia, where several meteorites fell in late 1886. 

The ureilites are subdivided into two groups: the monomict main group and the less common polymict group. Main group ureilites are composed largely of coarse-grained olivine and minor pyroxene, mostly in the form of calcium-poor pigeonite, set in a dark carbonaceous matrix of graphite and diamond, nickel-iron metal, and troilite. Our recent find, El Gouanem, Morocco, is a rather typical member of the main group. Polymict ureilites consist of a mixture of different lithologies. Besides clasts from main group ureilites, they contain magmatic inclusions, dark carbonaceous clasts, chondritic fragments of different origins, and various other inclusions. This suggests a surface or regolith origin for the polymict ureilites, an assumption that is supported by the values for noble gases that have been implanted into the regolith by the solar wind.
