Anhydrite - an overview ScienceDirect Topic

  1. Anhydrite (CaSO4) scale forms in the presence of acid sulphide water and calcium ions. Similar to calcite, anhydrite has retrograde solubility and also forms in production wells but is less common than calcite. Anhydrite solubility is independent of pH and generally forms close to the wellhead. Anhydrite scaling has been reported in several.
  2. Anhydrite is an important constituent of white, usually marginal, zones of amygdules residing within the slag sample LdS15 (Figure 13.2.7C and D).However, it is also found in the blue, apatite-group-bearing internal zones. An analytical report for anhydrite is given in Table 13.2.3.A unique feature of this anhydrite is the molybdenum admixture, which would likely act due to small substitution.

Anhydrite. Anhydrite is one of the minerals that make up the rocks. Chemical structure similar to Gypsum but does not contain water. Formula is CaSO4.There is a sedimentary basin in large areas where sea water evaporates. It is usually found in salt deposits with gypsum next to it. Anhydrite may form on the coastline or tidal flat deposits. Anhydrite is a mineral from the Calcium Sulphate family (CaSO4).

Diagenetic anhydrite is found in reservoir rocks as nodules and poikilotopic crystals, which have little effect on reservoir properties, and as pore-filling crystals, which reduce reservoir quality.

Anhydrite. In some hydrothermal vent areas and under certain temperature and pressure conditions the vent fluid actually boils beneath or at the seafloor. When this happens, the vent fluid may separate into two distinct phases, a vapor phase and a brine phase. Dissolved gases are concentrated in the vapor phase, whereas the dissolved metals are. Anhydrite, when dissolved, forms a solution of calcium sulfate, which at common temperatures and pressures is in equilibrium with the solid phase of gypsum, but not with anhydrite. The solubility. Mold pore cementation is the key factor constraining the reservoir property in the study area. The anhydrite dissolution pores in the Ordovician Majiagou Formation of southeastern Ordos Basin are commonly filled by minerals such as dolomite, calcite, pyrite, and quartz accounting for more than 90% of the total molds resulting in significant porosity volume reduction Anhydrite may hydrate into gypsum or gypsum may dehydrate into anhydrite depending upon the changes in the geochemical conditions. Hydration of anhydrite to gypsum may yield molar volume increases.

Among these, Asia Pacific was the largest region in the global anhydrite market in 2016 on account of the rapidly growing urbanization and industrialization in countries such as China, India, and others The name anhydrite was given by A.G. Werner in 1804, because of the absence of water, as contrasted with the presence of water in gypsum.. Encyclopaedia Britannica, 11th Edition, Volume 2, Part 1, Slice 1. It is frequently associated with minor quantities of anhydrite, which is calcium sulphate without water, and under the proper natural conditions either of these materials may be changed into.

Anhydrite Gypsum Contamination. Anhydrite and gypsum are calcium sulfate compounds (CaSO4) which are sometimes encountered while drilling. Gyp is calcium sulfate with water of crystallization (CaSO4 2H2O), while anhydrite is the anhydrous (waterless) form of calcium sulfate (CaSO4). These may occur as thin stringers or massive beds Anhydrite binder is widely used in the industry of construction and building materials worldwide. It is used as the floor levelling layer, for plastering, decorative panels. Shredded anhydrite is common in construction of roads, as the filling material - in production of concrete and mortar Anhydrite addition allows ettringite (C 6 AŠ 3 H 32) and gibbsite formation (Reaction II). Moreover, anhydrite is a natural product so its addition decreases the cost and the environmental impact of the binder Anhydrite may indicate precipitation at somewhat elevated temperature (> ~50 °C), as is often the case on Earth, but at Gale this interpretation is complicated by the various mixed-phase associations of bassanite + anhydrite, gypsum + anhydrite, and gypsum + bassanite + anhydrite. The common connection in all Ca-sulfate bearing samples is.
