Formation

Formation
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.   
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

Schist vs Flint 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 Flint Reserves. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel. 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 Flint information and Schist vs Flint characteristics in the upcoming sections.
