09011 - Almost Complete NWA Unclassified Ordinary Chondrite Meteorite 258.3 g Cedaria minor Late CretaceousThese meteorites were found in the Saharan Desert in Northwest Africa, likely by nomads. In order to classify them it would be necessary to cut off a section for analysis. Although they are exceedingly rare when compared to terrestrial rocks, these are the most abundant type of meteorite and are referred to as common chondrites. H and L (designating the amount of metal contained) type chondrites have been already extensively studied. Composed largely
