Low abundances of highly siderophile elements in the lunar mantle: evidence for prolonged late accretion

Abundances of the highly siderophile elements (HSE) Re, Ir, Os, Ru, Pt and Pd were determined for etchates and residues of highly purified lunar orange (74220 and 74001,1217 and 1218) and green (15421,65 and 15426,164) volcanic glasses. Most etchates have >100 pg/g Os and Ir, and in some instance...
