Formation
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.
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 Oil shale and Anorthosite Properties
Know all about Oil shale and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Oil shale belongs to Sedimentary Rocks while Anorthosite belongs to Igneous Rocks.Texture of Oil shale is Splintery whereas that of Anorthosite is Foliated, Glassy. Oil shale appears Muddy and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Oil shale is dull while that of Anorthosite is pearly to subvitreous. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. The commercial uses of Oil shale are an oil and gas reservoir and that of Anorthosite are creating artwork, curling.
