These are called detrital, chemical ...3) Chemical sedimentary rocks form as minerals dissolved in water precipitate out of solution. When salt water evaporates Halite (salt) and gypsum are deposited. Common examples: Rock salt, rock gypsum, anhydrite, chert. Sedimentary structures are features that formed as the sedimentary rock was deposited.Gypsum, common sulfate mineral of great commercial importance, composed of hydrated calcium sulfate.

The resulting plaster of Paris, when mixed with water, can be molded, shaped or spread, then dried or set to form hard plaster. Gypsum was used by the builders of the ...Chemical sedimentary rocks that form by the evaporation of water are called evaporites. Rock salt & rock gypsum are the two most common evaporites. Rock salt is composed of the mineral halite (NaCl - sodium chloride). It ranges in color from clearish to grayish to orangish-brown, but sometimes has other colors, such as blue.They can tell if a rock was formed on dry land, on an ocean floor, or deep inside the earth. ... halite (salt), calcite, anhydrite, gypsum, mica, and quartz also are found in Kansas.

It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers.The twins are formed when there are two or more crystals who share a portion of the same crystal lattice. Also, gypsum forms crystals that tend to be large in size (8). Luster: Pearly to resinous. ... Associated Rock types: The most common rock type associated with gypsum is rock gypsum. You can also find gypsum with the minerals sulfur ...It forms in lagoons where ocean waters high in calcium and sulfate content can slowly evaporate and be regularly replenished with new sources of water.
