I SHIP WORLDWIDE WITH DHL, UPS OR SIMILAR EXPRESS SERVICE, TRACKED & TRACED Ureilite meteorite arenamed after the Novo-Urei, Russia, fall of 1886, are ultramafic achondrites that contain interstitial carbon as graphite or diamond. The majority consist of olivine + uninverted pigeonite. In a few, the pyroxene is augite and/or orthopyroxene instead. In addition, about 10% of ureilites are polymict breccias, containing a few percent of feldspathic material in addition to typical ureilitic components.
