Greywacke vs Limestone

Greywacke vs Limestone 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 Limestone Reserves. Greywacke is defined as a dark coarse-grained sandstone rock which contains more than 15 per cent clay. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. 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.
