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.
