Fact sheet
Description: 

76565 and its companion 76566 were collected as rake samples. They are fairly coherent regolith breccias, with numerous small clasts of feldspathic material from the highlands and some clasts of mare material from the valley floor. The dark matrix is non-porous and is mostly glass, with a few percent mare and highland clasts. Orange glass occurring are sizeable irregular fragments and as small beads is also present. Our thin section contains a large white granulitic clast (rotation 1). Another granulitic clast and a plagioclase feldspar clast are shown in rotation 2.

The sample weighed 11.6 grams before analysis and has not been dated.
