Anorthosite and Suevite
Definition
Definition
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Anorthosite and Suevite Properties
Know all about Anorthosite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Anorthosite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Anorthosite is Foliated, Glassy whereas that of Suevite is Earthy. Anorthosite appears Layered, Banded, Veined and Shiny and Suevite appears Banded. The luster of Anorthosite is pearly to subvitreous while that of Suevite is earthy. Anorthosite and Suevite are available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. The commercial uses of Anorthosite are creating artwork, curling and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
