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.

Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
