The rock cycl e is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure.5.3.1 Lithification and Diagenesis. Lithification turns loose sediment grains, created by weathering and transported by erosion, into clastic sedimentary rock via three interconnected steps. Deposition happens when friction and gravity overcome the forces driving sediment transport, allowing sediment to accumulate.5.3.1 Lithification and Diagenesis.

The main types of sedimentary rocks are clastic or chemical. Some sedimentary rocks are a third type: organic. Clastic sedimentary rocks are made of sediments. The sediments differ in size. Chemical sedimentary rocks are made of minerals that precipitate from saline water. Organic sedimentary rocks are made from the bodies of organisms.Sedimentary rock - Silica, Clastic, Chemical: Those siliceous rocks composed of an exceptionally high amount of crystalline siliceous material, mainly the mineral quartz (especially microcrystalline quartz and fibrous chalcedony) and amorphous opal, are most commonly known as chert. A wide variety of rock names are applied to cherty rocks reflecting their colour (flint is dark chert; jasper is ...The large limestone rock formations, previously called dolomite, should have a new name, dolostone, or magnesian limestone. Calcium carbonate limestone is just limestone. Dolostone. Dolostone is a major sedimentary rock formation in the earth’s crust and joins with other sedimentary formations like shale, sandstone, and limestone.
