Metamorphic grade is an informal indication of the amount or degree of metamorphism. They are determined by the pressure and temperatures to which the rock has been subjected such areas are generally referred to as metamorphic core complexes. It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is.

It is derived from shale by regional metamorphism. It often contains significant amounts of mica which allow the rock to split into thin pieces. What is the metamorphic grade of marble. Metamorphic grade refers to the degree of heat and pressure needed to create a particular metamorphic rock out if its parent rock.

Metamorphic grades refer to the degree and intensity of the metamorphism. Marble is commonly used for sculpture and as a building material.
