Metamorphic rocksare transformed from existing rocks through intense heat, pressure, or chemical processes. These conditions alter the mineral composition and texture of the rock, creating unique features. Metamorphic rocks composition showcasing banded gneiss, smooth white marble, and soft grey soapstone....
A rock is:A solid Naturally occurring Is made up of minerals or mineral like matter. Sounds pretty simple right? There are some exceptions to the rule and some finer points that need a little explaining.Rock CompositionSome rocks are composed of just one mineral. Pyrite (iron sulfide)and...
The main factors that can affect the texture of an igneous rock are the location and cooling rate of the hot magma that forms the rock. If the magma... Learn more about this topic: Igneous Rocks Definition, Types & Examples from
What is Andalusite? Andalusite is an aluminosilicate mineral with a chemical composition of Al2SiO5. It forms at low to medium metamorphic temperatures and pressures where argillaceous rocks (such as shale) are exposed to regional and contact metamorphism. Andalusite is a rock-forming mineral most ...

A rock with a similar composition and appearance as granite,gneiss, can form through long and intense metamorphism ofsedimentary(paragneiss) origneousrocks (orthogneiss). Gneiss, however, is distinguished from granite by its strong fabric and alternating dark and light colored bands. ...
