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.
Pantellerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Anorthosite and Pantellerite Properties
Know all about Anorthosite and Pantellerite properties here. All properties of rocks are important as they define the type of rock and its application. Anorthosite and Pantellerite belong to Igneous Rocks.Texture of Anorthosite is Foliated, Glassy whereas that of Pantellerite is Eutaxitic. Anorthosite appears Layered, Banded, Veined and Shiny and Pantellerite appears Layered and Foliated. The luster of Anorthosite is pearly to subvitreous while that of Pantellerite is earthy. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas Pantellerite is available in dark greenish - grey colors. The commercial uses of Anorthosite and Pantellerite are creating artwork, curling.
