WebProtolithic - If a rock has undergone only slight metamorphism such that its original texture can still be observed then the rock is given a name based on its original name, with the prefix meta- applied. For example: metabasalt, metagraywacke, meta-andesite, metagranite. WebAnother major part of the family are rocks with a mafic igneous protolith. These include greenschists and blueschists. Green color is given to the former mostly by a chlorite group minerals. The latter contains bluish amphibole glaucophane. Sedimentary rocks that were rich in organic matter metamorphose to graphitic schists.
WebThe parent rock or protolith is the rock that exists before metamorphism starts. New metamorphic rocks can form from old ones as pressure and temperature progressively increase. The term parent rock is typically applied to the initial unmetamorphosed rock, rather than referring to each metamorphic rock that formed as metamorphism progresses.
