After a brief conversation with Dr. Carl Allen's wife Jackie, a
volcanologist, I seem to recall her saying that most of the glass on the
surface of the moon was basaltic in nature, from volcanic action billions of
years ago when the moon's center was still hot enough to produce magma. The
glass was then pulverized into tiny bits by micrometeorites.
