Electron microprobe and petrographic analyses of an Apollo 15 sample, 15382, from the Apennine Front, have revealed KREEP chemistry and very low concentrations of the characteristic meteorite siderophile elements: Ir, Os, Re, Au, and Ni. It is a crystalline basalt, practically identical in texture and mineral zoning patterns to other lunar high-alumina basalts.
