5 Formation

5.1 Formation

Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

Migmatite vs Soapstone Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Migmatite and Soapstone Reserves. Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components. It is a metamorphic magnesium rich rock because it is composed of the mineral talc. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes.
