Precipitation of gypsum due to evaporation of seawater produces which kind of sedimentary rock?
Thu Feb 20 2003 13:30:00 GMT-0500 (Eastern Standard Time) · Evaporite is the term for a water-soluble mineral sediment that results from concentration and crystallization by evaporation from an aqueous solution. There are two types of evaporite deposits: marine which can also be described as ocean deposits and non-marine which are found in standing bodies of water such as lakes. Evaporites are considered sedimentary rocks …
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. Gypsum is the most common sulfate …

Mon Aug 15 2005 14:30:00 GMT-0400 (Eastern Daylight Time) · The first sink is the burial of sulfate either as marine evaporites (e.g. gypsum ) or carbonate-associated sulfate (CAS) which accounts for 6 × 10 13 g/year (δ 34 S = +21‰). The second sulfur sink is pyrite burial in shelf sediments or deep seafloor sediments (4 × 10 13 g/year; δ 34 S = …
