Formation
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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
