Schist vs Blue Granite 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 Schist and Blue Granite Reserves. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar. 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 Schist vs Blue Granite information and Schist vs Blue Granite characteristics in the upcoming sections.
