Other data Lithic fragments < 2 mm in size, oriented. Aug present only as isolated crystals. One igneous-textured clast consists of euhedral Ol (Fo85-88, CaO 0.1 wt%), Low-Ca Px (E68-71 Wo13-8) and skeletal Ca-rich Px in a Fds Fe-rich glass. Two very-fine grained clasts similar to matrix of CC are present. Kamacite and troilite are present. Carbon-rich veins and pockets are common. Diamond (cathodoluminescence detected) are abundant as small grains only within carbonaceous areas.
