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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

All about Anorthosite and Turbidite Properties
Know all about Anorthosite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Anorthosite belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Anorthosite is Foliated, Glassy whereas that of Turbidite is Mud-rich, Sandy. Anorthosite appears Layered, Banded, Veined and Shiny and Turbidite appears Dull and Banded. The luster of Anorthosite is pearly to subvitreous while that of Turbidite is metallic. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas Turbidite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Anorthosite are creating artwork, curling and that of Turbidite are cemetery markers, creating artwork.
