sedimentary rocks. rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. such material, called detritus, consists of fragments of rocks and minerals.when the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation.,list of important sedimentary rocks geology,gypsum it is a sedimentary rock composed of the mineral of the same name-gypsum, which has a composition of caso 4.2h 2 o. its common colour is white but it may also occur in other shades such as yellow, red or dark grey due to impurities present in the rock. gypsum is formed in nature as a result of evaporation from sea-waters rich in
sedimentary rocks are formed by the lithification of inorganic andor organic sediments, or as chemical precipitates. there are two types of sedimentary rocks clastic and chemical clastic sedimentary rocks form when existing parent rock material is weathered, fragmented, transported, and deposited in layers that compact,,is halite a clastic sedimentary rock,clastic or detrital rocks are made of clay, silt, sand, gravel, andor boulders. evaporite rocks form when sea water or lake water dries up and precipitates gypsum caso4 2h2o, halite nacl, or other minerals. evaporites are chemical sedimentary rocks.
