Formation

Formation
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.   
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Breccia vs Schist 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 Breccia and Schist Reserves. Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. 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 Breccia vs Schist information and Breccia vs Schist characteristics in the upcoming sections.
