Great information on lunar anorthosite and check out the "zap pits"

"Tiny impact craters, called""zap pits"" are produced by small, high
velocity particles and are common on the exposed faces of lunar rocks.
This zap pit is 50 microns (2/1000 inch) in diameter and has a raised
rim of glassy material caused by the impact."
