To do so, you will observe various properties of sedimentary rocks such as type, grain size/composition ...In order for a rock to be considered a claystone, it must consist of at least fifty percent clay whose particle measures less than 1/256 of a millimeter in size. Mudstone (Clastic Sedimentary Rock) a fine-grained, clastic sedimentary rock, composed of a mixture of silt- and clay- sized rocks and mineral fragments, especially quartz and calcite. The size of the individual rock sample examined at the surface is rather small because it is limited by the size of drill cuttings and rock strength. Weak rocks, ones without cement, are often reduced to original detrital grain size by the drilling process, making it difficult to determine rock type, but still possible to determine lithology.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. Table 4.2 shows some common types of sedimentary rocks and the types of sediments that make them up. Figure 4.12: This cliff is made of a sedimentary rock called sandstone.ROCK GYPSUM . Rock gypsum (a.k.a. gyprock) is a chemical sedimentary rock. It is an example of an evaporite - it forms by the evaporation of water (usually seawater) and the precipitation of dissolved minerals. Rock salt & rock gypsum often occur together in evaporitic successions. Rock gypsum is composed of the mineral gypsum (CaSO 4 ·2H 2 O - hydrous calcium sulfate).Table A: The Udden-Wentworth grain-size scale for classifying sediments and the grains that make ... 3.1.
