G. Cressey, in Encyclopedia of Geology, 2005 Introduction. Gypsum (CaSO 4 · 2H 2 O), the most common of the sulphate minerals, is also known as alabaster (a fine-grained massive form), satin spar (a fibrous variety of gypsum), or selenite (colourless transparent gypsum crystals). Gypsum is often found in considerable thicknesses within evaporite sequences and in association with Formation of gypsum and bassanite by cation exchange,2011-9-27 · Epsomite dehydrated to hexahydrite with decreasing RH in samples that initially contained montmorillonite and epsomite . Epsomite formed once again and was accompanied by the formation of gypsum at higher RH. Both epsomite and gypsum persisted until the end of the experiment when RH returned to a near-ambient value (50%).
Conversely, lack of gypsum in CheMin samples indicates that it was initially absent, or below detection limits. Rapin et al.

With the presence of 10% and 20% gypsum, AFt was formed as major compound at only 5 hours, with a consumption of gypsum. Monosulfate phase was formed as minority. With thermal cycle treatment, AFm was slightly
SEM and EDX examination showed that coatings of calcite had formed on the gypsum particles. The sandy clay loam was also extracted using an open system in which either air or air + 1% CO 2 was bubbled through the suspensions for 1 h with stirring. The gypsum dissolved more rapidly and all of the gypsum dissolved.GEOLOGICAL ORIGINS OF THE BAROLO WINEGROWING ,2021-12-4 · The most ancient origins of the Langhe date back to around 30 million years, during the lower Oligocene. The first deposits are to be found in the south east (Ceva, Millesimo, Cairo Montenotte), forty kilometres from the Barolo growing area: salt marsh sediments represent the entry of the sea into the narrow valleys of the early Alps, with
Ettringite was formed after the reaction between gypsum and aluminum from the slag and fly ash; however, its formation was hindered in the presence of Gypsum products SlideShare,2016-12-18 · • Gypsum products used in dentistry are formed by driving off part of the water of crystallization from gypsum to form calcium sulphate hemihydrate. • Gypsum → Gypsum product + water • 2CaSO4·2H2O → (CaSO4)2·H2O +
The gypsum was formed initially by displacive growth 117 Fig. 2: Thin-section photomicrograph of kerogeneous ostracoda wackestone with large, discoidal gypsum crystals formed initially by displacive growth in a intertidal-supratidal sabkha environment.The Nature and Significance of Variations In Gypsum,The results show that a non-lenticular crystal habit of gypsum occurring within the groundmass (sediment matrix) indicates synsedimentary precipitation. In contrast, a lenticular crystal habit cannot be used in isolation as an indicator of the environment in which
gypcrete, gypsum-cemented duricrust, an indurated, or hardened, layer formed on or in soil. It generally occurs in a hot, arid or semiarid climate in a basin that has internal drainage. It usually is composed of about 95 percent gypsum (a hydrated calcium sulfate mineral) and is initially dGypsum, bassanite, and anhydrite at Gale crater, Mars,Conversely, lack of gypsum in CheMin samples indicates that it was initially absent, or below detection limits. Rapin et al. (2016) analyzed ChemCam laser ablation data of H abundance and found hydration equivalent to bassanite in surface analyses of Ca-sulfate veins, at laser depths of a few micrometers.

Addition of gypsum resulted initially in formation of C sub 3 A. CSH sub 12 with a minor amount of ettringite. With both chloride and gypsum, major products were C sub 3 A.
