Greywacke vs Mylonite

Greywacke 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 Greywacke and Mylonite Reserves. Greywacke is defined as a dark coarse-grained sandstone rock which contains more than 15 per cent clay. 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.
