Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
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.
