Archaeological Significance
Formation
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.
Sovites are formed due to low degrees of partial melting of rocks.

All about Anorthosite and Sovite Properties
Know all about Anorthosite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Anorthosite and Sovite belong to Igneous Rocks.Texture of Anorthosite is Foliated, Glassy whereas that of Sovite is Granular, Poikiloblastic. Anorthosite appears Layered, Banded, Veined and Shiny and Sovite appears Dull, Banded and Foilated. The luster of Anorthosite is pearly to subvitreous while that of Sovite is subvitreous to dull. Anorthosite and Sovite are available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. The commercial uses of Anorthosite are creating artwork, curling and that of Sovite are an oil and gas reservoir, as a feed additive for livestock, creating artwork, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
