If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. Note the quarter for scale. This conglomerate is made up of pebbles surrounded by a. Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders. read more
Clastic sedimentary rocks form by weathering processes which break down rocks into pebble, sand, or clay particles by exposure to wind, ice, and water. read more
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. read more
Clastic sedimentary rocks are formed from the buildup of clatics: small pieces of fragmented rocks deposited as a result of mechanical weathering then lithified by compaction and cementation. Examples of Clastic sedimentary rocks include sandstone, shale, siltstone, and breccias. read more
