compaction -- pressure due to overlying sediments cementation -- calcite, silica, and iron oxide act as cements Sedimentary Rocks Types of Sedimentary Rocks Clastic Sedimentary Rocks formed from sediment particles that originate from mechanical weathering classified by size of sediment particles that they form from Sediment Clastic Rock Name gravel conglomerate (if gravel rounded) breccia (if gravel angular) sand sandstone silt siltstone clay shale Chemical Sedimentary Rocks formed from sediment that originated from the soluble substances produced by chemical weathering and carried away in solution.
