Formation
Granophyre 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.
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.

All about Granophyre and Anorthosite Properties
Know all about Granophyre and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Granophyre and Anorthosite belong to Igneous Rocks.Texture of Granophyre is Granophyric whereas that of Anorthosite is Foliated, Glassy. Granophyre appears Veined or Pebbled and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Granophyre is dull to grainy with sporadic parts pearly and vitreous while that of Anorthosite is pearly to subvitreous. Granophyre is available in black, grey, orange, pink, white colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. The commercial uses of Granophyre are curling, gemstone, laboratory bench tops, tombstones and that of Anorthosite are creating artwork, curling.
