Definition

A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin

Etymology

From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

From an old Swedish mining term originally used to describe a type of silicate gangue or waste rock.

Formation

Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
