The occurrence of gypsum within the Fika Shale in the Gongola Basin Upper Benue valley was first reported by Carter et al., (1963) and confirmed by Reyment (1965). Orazulike (1988) reported gypsum occurrence in Nafada and Bajoga areas of northeastern Nigeria. There had not been a proper documentation of the gypsiferous bodies in these areas since then. The present work is designated to .

occurrence of gypsum. In gypsum .is an important constituent of cap rock, an anhydritegypsum rock forming a covering on salt domes, as in Texas and Louisiana. Very commonly it is formed from the hydration of anhydrite by surface waters and groundwaters, and, thus, many gypsiferous strata grade downward into anhydrite rocks. This replacement causes a.

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

18/08/2014· The composition of the xylem sap of gypsum plants during summer shows closer values to gypsum crystallization water than to free soil water. Crystallization water represents a significant water source for organisms growing on gypsum, especially during summer, when it accounts for 7090% of the water used by shallowrooted plants. Given the widespread occurrence of gypsum in dry lands ...

Occurrence Anhydrite is most frequently found in evaporite deposits with gypsum; it was, for instance, first discovered, in 1794, in a salt mine near Hall in Tirol. In this occurrence, depth is critical since nearer the surface anhydrite has been altered to gypsum by absorption of circulating ground water.

Occurrence. Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. The largest deposits known occur in strata from the Permian age. Gypsum is deposited in 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 ...
