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.
