Sedimentary rocks made of cemented, non-organic sediments are called clastic rocks. Those that form from organic remains are called bioclastic rocks, and sedimentary rocks formed by the hardening of chemical precipitates are called chemical sedimentary rocks. Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al 2 Si 2 O 5 4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.
