The Question

(Submitted March 29, 1998)

What are some of the substances found on the moon ?

The Answer

There is a good, readable account of what the Apollo astronauts found on the moon in the July 1994 issue of Scientific American. I would recommend that article to you. Here is a list of some of the substances that are mentioned in the article:

plagioclase feldspar, olivine, pyroxene, anorthosite

The article does a good job of describing how the presence and/or absence of certain elements on the moon led to what is now considered by many scientists as the correct theory of its formation.
