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

More about Flint and Schist
Here you can know more about Flint and Schist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Flint and Schist consists of mineral content and compound content. The mineral content of Flint includes Silicon and mineral content of Schist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc. You can also check out the list of all Sedimentary Rocks. When we have to compare Flint vs Schist, the texture, color and appearance plays an important role in determining the type of rock. Flint is available in black, brown, green, grey, red, white colors whereas, Schist is available in black, blue, brown, dark brown, green, grey, silver colors. Appearance of Flint is Glassy or Pearly and that of Schist is Layered and Shiny. Properties of rock is another aspect for Flint vs Schist. The hardness of Flint is 7 and that of Schist is 3.5-4. The types of Flint are Not Available whereas types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist..
