Sedimentary rocks below the surface normal temperature and pressure conditions, the weathered material, volcanic debris, and a small amount of organic matter in the universe by the transport, deposition and diagenesis of layered rock. Causes can be divided by rocks, clay, rocks and rock chemistry (including biochemistry rock). common sedimentary sandstone, tuffaceous sandstone, conglomerate, claystone, shale, limestone, dolomite, chert, rock iron, phosphorus rocks, so limestone sedimentary rocks belong.

Limestone is one of the most widely distributed minerals in the crust of. Lakes in the deposition of calcium carbonate, after the loss of water, pressed together to form a cemented rock called limestone.
