5.1 Formation
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.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

Soapstone vs Mylonite 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 Soapstone and Mylonite Reserves. It is a metamorphic magnesium rich rock because it is composed of the mineral talc. Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism. 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. You can check out Soapstone vs Mylonite information and Soapstone vs Mylonite characteristics in the upcoming sections.

Soapstone vs Mylonite Characteristics
