WebCHEMICAL SEDIMENTARY ROCKS - formed when dissolved substances precipitate from water to form sediments and eventually rock; include salts such as ROCK SALT, GYPSUM, and LIMESTONE, and biochemically mediated rocks such as peat, and reef rock (an organic limestone). TYPES OF DETRITAL SEDIMENTARY ROCKS WebThese are called solution sinkholes. These rocks dissolve when attacked by rainfall or groundwater that is acidic. Solution sinkholes have sides that vary from gentle slopes to almost vertical, while their shapes include saucer-like hollows, cones, cylindrical potholes and shafts. Streams or rivers may enter a sinkhole and disappear underground.
Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins. Hydrothermal anhydrite in veins is commonly hydrated to gypsum by groundwater in near-surface exposures. It is often associated with the minerals halite and sulfur. …
