Formation

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