It seems understatement to say that Almahata Sitta is polymict given that it contains at least twelve lithologies. Since the lithologic types are dominated by ureilites, though, it is classified as a polymict ureilite. Much of the remainder is EL and EH chondrites of various petrographic grades, melts and breccias. Also found are H and L ordinary chondrites and a unique chondrite. Roger Warin and I wrote about Almahata Sitta for Meteorite magazine’s February 2012 issue. Our Centerpiece article used some of the following pictures.
