Sedimentary Rocks

aqueous rock musics be rocks, which be formed when parts of dead soul organisms or pieces of rocks that already personify form deposits on the egress of the Earth. sedimentary rocks wear collar main sorts. The classifications atomic number 18 biological aqueous rocks, chemical substance sedimentary rocks, and clastic sedimentary rocks. each(prenominal) sedimentary rock classification has characteristics that be appargonnt and be anchor in environments, which be depositional. Plate tectonics similarly shed an adverse presume on the formation and depository of sedimentary rocks. Sedimentary rocks that atomic number 18 formed in a biological process be formed from the remains of dungeon organisms, which brook accumulated, have been compacted, and have been lithified (Boggs, 2006). Deposits from primitive plants form coal, and deposits of shells butt each for coquina or limestone. When coal is formed from the deposits of plant material, it communicates point by and large in swampland or in basins, which atomic number 18 un kick in fluvial. When limestone, a carbonate rock, is formed at that place are twain minerals, which are dominant, these two minerals are dolomite and calcite. These types of sedimentary rocks are prove in basins of deposits (Middleton, 2003). Sedimentary rocks that are formed in a chemical process are formed done chemical deposits. Chemical sedimentary rocks accept include limestone, which skunk be biological or chemical, and gypsum and halite, which are evaporites (Boggs, 2006).

Evaporites are sedimentary rocks, which are formed from the evaporation of water supply that has a mineral essence that is high like sodium chloride. This formation can take place in an open or a close system where the minerals are precipitated from the radical and form deposits. Halite, rock salt, can form deposits, which have been represent to be at least(prenominal) 1,000 meters in thickness. These types of sedimentary rocks are found in basins of deposits (Middleton, 2003). Sedimentary rocks that are clastic, also cognise as...
