Classification of Sedimentary Rocks | Engineering Geology, E Classification of Sedimentary Rocks by Chemical Action: , Gypsum (Ca SO 4 2H 2 O) is closely related to salt in its origin like rocks salt Gypsum too is a product of the evaporation of sea water Gypsum is less soluble than salt and thus is precipitated earlier when sea water is evaporatedSedimentary Rock: Types And How They Are Formed? (2020 ,, Jul 23, 2020· Gypsum is a type of chemical sedimentary rock that is soft and can be distorted easily It is normally white in color and is utilized in the production of plaster of Paris Limestone Limestone belongs to the group of chemical sedimentary rocks formed from mineral calcite It is usually challenging to visually identify limestoneGeoMan's Sedimentary Rock Identification Chart, Rock Name: Clastic Coarse Grains >2 mm: Any rock type (quartz, chert, or quartzite most common) Rounded clasts : Conglomerate: Angular clasts: Breccia: Fine Grains 1/16 to 2 mm Can be seen w/ naked eye: Quartz with minor accessory minerals: White, tan, brown; sandpapery feel: Quartz Sandstone: S A N D S T O N Esedimentary rock | Definition, Formation, Examples ,, Nov 05, 2020· Orthochemical sedimentary rocks, on the other hand, consist of dissolved constituents that are directly precipitated as solid sedimentary rock and thus do not undergo transportation Orthochemical sedimentary rocks include some limestones, bedded evaporite deposits of halite, gypsum, and anhydrite, and banded iron formationsList of Top 15 Sedimentary Rocks | Geology, Sedimentary Rock # 1 Arkose: This is a sedimentary rock with a high feldspar content (usually orthoclase or microcline), derived from weathering of feldspar-rich rocks like granites and gneiss It contains some rock fragments and micas in a fine grained matrix Red colouration is caused by the presence of hematite and iron staining.
