Abstract

We have studied anorthositic clasts in the Y-86032 and Dhofar 908 meteorites by the Rb-Sr, Sm-Nd, and Ar-39-Ar-40 techniques combining isotopic studies with mineralogical/petrological studies of the same clasts. As a result of these studies, we conclude that the lunar crust is composed of a variety of anorthosites, at least some of which must have formed as plutons in the earliest formed ferroan anorthosite crust.
