Sample Description

"Results of petrographic examination: Single crystal 2 x 0.5 x 1 cm and one large piece 4 x 0.5 x 1. cm. One dirty surface and sulfide inclusions which were separated by crushing and hand picking. Under petrographic microscope, some grains show a little alteration and inclusions or voids along cleavage directions - possible exsolved pyroxene?" Salisbury, J. W., Walter, L.
