Back when the moon first formed, it was completely molten. As it cooled, one of the first minerals to form was anorthite. Since the anorthite was less dense than the surrounding magma, it floated up and formed rock made mostly of anorthite called anorthosite. Later, giant impacts on the moon left huge craters.

Anorthosite /ænˈɔːrθəsaɪt/ is a phaneritic, intrusive igneous rock characterized by its composition: mostly plagioclase feldspar, with a minimal mafic component. Pyroxene, ilmenite, magnetite, and olivine are the mafic minerals most commonly present. Anorthosites are of enormous geologic interest, because it is still not fully understood how they form. Most models involve separating plagioclase crystals based on their density. Plagioclase crystals are usually less dense than magma; so ...
