* Anorthosite: This is a light-colored, feldspar-rich rock that makes up the lunar highlands. It's thought to have formed early in the Moon's history from a magma ocean.

* Basalt: Darker, volcanic rocks that form the maria (dark, smooth plains) on the Moon. They were formed by volcanic eruptions billions of years ago.

* Breccia: A rock type made of fragments of other rocks cemented together. It's common on the Moon due to the constant bombardment by meteoroids.

In addition to these major components, the Moon's crust also contains traces of other minerals, such as:

* Olivine

* Pyroxene

* Ilmenite

* Titanium

The exact composition of the Moon's crust varies depending on location. The highlands are generally richer in anorthosite, while the maria are richer in basalt.
