Sediment = loose particulate material (clay, sand, gravel, etc.) Sediment becomes sedimentary rock through lithification , which involves: Compaction Cementation Recrystallization (of carbonate sediment) Types of sedimentary rocks Overview Terrigenous (detrital or clastic) Conglomerate or Breccia Sandstone Siltstone Shale Chemical/biochemical Evaporites Carbonate sedimentary rocks (limestones and dolostone) Siliceous sedimentary rocks Organic (coals) Other - ironstones Sedimentary Structures Sedimentary Environments Fossils A. Terrigenous (also called detrital or clastic) Terrigenous sedimentary rocks are derived from the weathering of pre-existing rocks, whch have been transported to the depositional basin .
