Anorthite

: During the early cooling of the Moon, anorthite crystals were less dense than the surrounding basaltic magma. They floated to the surface, forming a thick crust of anorthosite (a rock composed of 90–100% plagioclase).

: Typically white, grey, or colorless; can also appear yellowish or reddish. anorthite

: On Earth, pure anorthite is restricted primarily to basic and ultrabasic igneous rocks like gabbro, picrite, or specialized formations such as the Adirondack Mountains . : During the early cooling of the Moon,

: Studies suggest that ancient anorthite crust subducted into Earth's mantle may accumulate at depths of 660–720 km rather than returning to the surface. 3. Industrial and Scientific Applications anorthite

Anorthite is central to the "Magma Ocean" theory of lunar formation.
