Question

write notes or geneis, schist, marble, quartizi​

Answer 1

Answer:

Schist is medium grade metamorphic rock, formed by the metamorphosis of mudstone / shale, or some types of igneous rock, to a higher degree than slate, i.e. it has been subjected to higher temperatures and pressures.

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. ... In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.

Quartz is silicon dioxide, SiO2, the second most common mineral in the crust of the earth (less common than feldspar). Although found in abundance in nearly all rock types, gem quartz nearly always comes from igneous rocks, principally pegmatites and cavities in volcanic rock, or from hydrothermal veins.
