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