What is the parent rock for schist?

What are the parent rock of metamorphic rocks?
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock.
What is parent rock made of?
In soil formation the parent rock (or parent material) normally has a large influence on the nature of the resulting soil; for example, clay soil is derived from mudstone while sandy soil comes from the weathering of sandstones. Parent rock can be sedimentary, igneous or metamorphic.
What is the parent rock of gneiss?
Gneiss is a medium- to coarse-grained rock formed under high grade-metamorphic conditions. Gneiss is primarily composed of quartz, potassium feldspar, and plagioclase feldspar with lesser amounts of biotite, muscovite, and amphibole. Granites and sometimes rhyolite provide the parent rock for gneiss.
How is chlorite schist formed?
Chlorite schist is typically formed by metamorphism of ultramafic igneous rocks, as is talc schist. Talc schist also forms from metamorphosis of talc-bearing carbonate rocks formed by hydrothermal alteration.
What are parent materials?
Parent material is the geologic material from which soil horizons form. There are seven variations of parent material. Weathered Bedrock, Till, Outwash Deposit, Eolian Sand, Loess, Alluvium, and Local Overwash. Here are the rules for distinquishing which one to pick on the scorecard.
Which rock is parent rock and why?
Parent rock can be sedimentary, igneous or metamorphic. In the context of metamorphic rocks, the parent rock is the original rock before metamorphism occurred.
What is marble parent rock?
The presence of the foliated rock, likely slate, suggests that, before this rock metamorphosed, it was composed of limestone (the parent rock of marble) layered with small-grained sedimentary rocks, like siltstone or shale.
