Schist: Metamorphic Rock - Pictures, Definition & More

Schist is a foliated metamorphic rock made up of plate-shaped mineral grains that are large enough to see with an unaided eye. It usually forms on a continental side of a convergent plate boundary where sedimentary rocks, such as shales and mudstones, have been subjected to compressive forces, heat, and chemical activity.

Mineral resources of igneous and metamorphic origin

Like igneous rocks, metamorphic rocks almost exclusively form at plate boundaries. ... silver, gold, and platinum. These elements do not enter rock-forming minerals as the magma crystallizes, so they remain in the fluid. In addition, hydrothermal fluids also react with minerals in the surrounding rocks, and

Pyrite - Wikipedia

Pyrite is the most common of sulfide minerals and is widespread in igneous, metamorphic, and sedimentary rocks. It is a common accessory mineral in igneous rocks, where it also occasionally occurs as larger masses arising from an immiscible sulfide phase in the original magma. It is found in metamorphic rocks as a product of contact metamorphism.
