Anorthite

, which is less dense than many other silicate minerals like olivine or pyroxene.

Anorthite ( ) is the calcium-rich end-member of the series. While it is a primary rock-forming mineral that is relatively rare in its pure form on Earth, it is a dominant component of the lunar highlands . 1. Composition and Physical Properties anorthite

Beyond its role in geology, anorthite has significant utility in manufacturing and high-tech research: , which is less dense than many other

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

: Approximately 6 to 6.5 on the Mohs scale, often used to distinguish it from softer minerals like marble or quartzite. Density : Approximately
