Conglomerate is a clastic sedimentary rock that is formed by the accumulation of rock fragments greater than 2 millimetre in size. The rock fragments that forms the conglomerate are round in shape. The pore spaces in between the clast of a rock are filled by the finer particles usually silt and clay or any other cementing material that binds the rock fragments together.
Conglomerate can be formed of any rock material that is transported through time and space from the origin area to accumulation area. The rounded rock fragments is the proof of transportation of the rock fragments in the conglomerate. The rock fragments of the conglomerate can be derived from igneous, metamorphic or sedimentary rocks. The chemical binding material can be sand, silt or chemical cement like calcite.
Generation of conglomerate
Conglomerate can be formed at an areas where strong water current exist like mountain down slope where water has enough current flow that it can carry the rock fragments above 2 millimetre. It can also be formed at beaches where water current is strong and rock fragments are available to be accumulated for forming conglomerate. Conglomerate is formed when large clast pebble or cobble size fragments transported and deposited than the finer grained fills the spaces in between the clast.
Conglomerate has very few uses because of it not clean breakage and fine particles are unreliable. It can only be used as a crush where low performance material is wanted.
