Metamorphic rocks composition showcasing banded gneiss, smooth white marble, and soft grey soapstone. Foliated Metamorphic Rocks:These rocks exhibit a layered or banded appearance due to the alignment of minerals under pressure.Examplesinclude slate, schist, and gneiss.

A crystalline, granular rock, consisting of quartz, feldspar, and mica, and usually of a whitish, grayish, or flesh-red color. It differs from gneiss in not having the mica in planes, and therefore in being destitute of a schistose structure. Granite Plutonic igneous rock having visibly cryst...
Rocks that are buried and changed by heat and gradual pressure are referred to as foliated, or layered, metamorphic rocks. Over time, the increased pressure of burial will cause foliated metamorphic rocks to continue changing into different rocks. Slate, phyllite, schist, gneiss and migmatite are...
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. ...
