Please read http://en.wikipedia.org/wiki/Moon.
Especially the part on the crust composition of the
moon. The abundance of oxygen, silicon, iron and
aluminum make it very attractive. The only thing the
moon is lacking that is needed for construction is
nickel.

Also, this page is slightly misleading in that it does
not break up the composition of the marias from
highlands where distribution of materials differ.
Something I hope gets remedied sooner or later (hint
hint).
