05797 - Fully Complete NWA L-H Type Unclassified Ordinary Chondrite Meteorite 4.5g Psammechinus roberti from the Agua NuevaThese 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
