It is monoclinic with a body centered lattice similar to those of anorthite. The following table shows their compositions in terms of constituent anorthite and albite percentages. Therefore, minerals in soil such as anorthite or wollastonite have no time for nucleation-crystal growth. It represents a plagioclase with less than 10% anorthite content. The lunar highland material anorthite can be used as aluminium ore. There are several named plagioclase feldspars that fall between albite and anorthite in the series. CaAlSiO. Anorthite is found in mafic igneous rocks. The crystals are a solid solution of 97% anorthite and 3% albite. Their commonest minerals are olivine, anorthite, hornblende, augite, biotite and leucite. Though lawsonite and anorthite have similar compositions, their structures are quite different. The feldspar is a basic variety of plagioclase (anorthite or bytownite). Raw lunar anorthite could also be used for making fiberglass and other ceramic products. It has some resemblance to anorthite, and it has four distinct polymorphs. Solid solutions between albite and anorthite are called "plagioclase", or more properly "plagioclase feldspar". The basic soda-lime feldspars (labradorite to anorthite) are those that undergo this type of alteration.
