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.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
