Sedimentary Rocks. Picture Gallery of the Most Common Rock Types. Breccia is a clastic sedimentary rock that is composed of large (over two millimeter diameter) angular fragments. The spaces between the large fragments can be filled with a matrix of smaller particles or a mineral cement which binds the rock together.
Sedimentary rocks are formed from pebbles, sand, silt, or clay. They are made from the end products of erosion, which breaks down rock into tiny pieces. Streams carry the tiny eroded fragments of stone to lakes and oceans, or spread them out over the flood plains of of rivers.
