Definition
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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 Serpentinite and Anorthosite Properties
Know all about Serpentinite and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite belongs to Metamorphic Rocks while Anorthosite belongs to Igneous Rocks.Texture of Serpentinite is Earthy whereas that of Anorthosite is Foliated, Glassy. Serpentinite appears Rough and Dull and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Serpentinite is waxy and dull while that of Anorthosite is pearly to subvitreous. Serpentinite is available in black, brown, green, grey, white colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Anorthosite are creating artwork, curling.
