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.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
