Major types of clastic sedimentary rocks are (from fine to coarse constituent clasts): mudstone: clay ("blocky") and shale (splits easily) siltstone sandstone sedimentary conglomerate or breccia. Clastic sedimentary rocks are classified mainly on the basis of texture, with sensible names that refer to the size of material they contain.Organic sedimentary rocks form from the accumulation and lithification of organic debris, such as leaves, roots, and other plant or animal material. Rocks that were once swampy sediments or peat beds contain carbon and are black, soft, and fossiliferous. Rich enough in carbon to burn, coal is an organic sedimentary rock that is a widespread and important …

Detritus sedimentary rocks are formed when rock fragments, debris or sediments accumulate over time and can be either organic or inorganic in makeup. These detrital rocks come together under great pressure, usually over many years. The debris, or matter that form the rocks, can be either organic or inorganic. A chunk of coal.

Clastic sedimentary rocks are classified according to the grain size of the sediment and the kinds of rock fragments that make up the sediment (Table ). Grain size is largely a function of the distance the particle was transported.
