Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

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.
