5 Formation

5.1 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.

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
