60629 is an anorthosite with a cataclastic texture. Attached to it is a patch of black glass. The pyroxenes in 60629 indicate that this sample is ferroan anorthosite.
Our thin section shows both anorthosite and the glass. The glass contains skeletal and dendritic olivine and pyroxene phenocrysts. There is a contact zone enriched in troilite and metallic iron.
The sample weighed 4.9 grams before analysis and has not been dated.

The Apollo 16 landing site was in the hilly region around Descartes crater in the lunar highlands. The landing spot was chosen to allow the astronauts to gather geologically older lunar material (Descartes Formation and the Cayley Formation) than the samples obtained in the first four landings, which were in or near lunar maria.
The mission lasted 11.1 days, with a stay on the lunar surface of 71 hours. The crew were on the lunar surface for 20.2 hours during which they traversed approximately 27 kilometers and collected approximately 96 kilograms of samples.
Apollo 16 was launched on 16 April 1972.
