60215 is actually a polymict breccia, because it contains clasts of material other than anorthosite. However, the largest portion is almost pure white and very plagioclase rich. Low Ni, Co and C contents suggest that the main portion of 60215 can be considered “pristine”. The rock was apparently originally encased in black glass, which has been eroded or chipped away by micrometeorite bombardment.
The anorthositic portion is both highly shocked and cataclastic. The brown mottled fragments are also of plagioclase composition (probably devitrified maskelynite) in which abundant, minute (<1 mm) mafic inclusions occur. Plagioclase fragments are relatively coarse, while pyroxene fragments are rare and generally less than 0.1 mm across, except for one texturally-distinct, millimeter-size, shocked and strongly zoned pigeonite clast. This clast has granular exsolution due to partial inversion, and has minor intergrown olivine. A second, smaller fragment adjacent to this pigeonite is extremely Fe rich (Wo20En55). These two zoned pyroxene fragments appear to be exotic. Low-Ca pyroxene compositions are heterogeneous; subordinate high-Ca pyroxene is more homogeneous. Rare chromite and olivine are also present.
The sample weighed 386 grams before analysis.
