How Is Siltstone Formed?

Full Answer Coarser rock particles are classified as sand or gravel and form sandstone breccia or conglomerate rock as they are cemented together by heat and pressure Very fine rock particles form a type of sedimentary rock known as shale or mudstone As the particles of eroded rock travel with water the edges of the rock are worn by
