Please note that the schools of literary criticism and their explanations included here are by no means the only ways of distinguishing these separate areas of theory. Indeed, many critics use tools from two or more schools in their work.
Conglomerate is a clastic sedimentary rock that contains large (greater than two millimeters in diameter) rounded clasts.
Conglomerate and metaconglomerate rock begin as particles of rock and sand collected in the sediment of streams, rivers or oceans. Conglomerate rock is a type of sedimentary rock that can become metaconglomerate rock through geological events, such as tectonic plate collision or subduction.
