Rock gypsum texture.
Gypsum occurs in extensive beds associated with other evaporite minerals (e.g., anhydrite and halite), particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite.It also occurs in considerable quantity in saline lakes and salt pans and is an important constituent of cap rock, an anhydrite-gypsum rock forming a covering on ...

Texture: Sedimentary rocks may have clastic (detrital) or non-clastic texture. Clastic sedimentary rocks are composed of grains, fragments of pre-existing rocks that have been packed together with spaces (pores) between grains. These
Rock salt & rock gypsum often occur together in evaporitic successions. Rock gypsum is composed of the mineral gypsum (CaSO 4 ·2H 2 O - hydrous calcium sulfate). Heating of gypsum or rock gypsum drives off the water, leaving only calcium sulfate behind (the mineral anhydrite). Adding water to anhydrite results in the formation of gypsum again.

Both can be scratched with a steel nail. Rock gypsum (H = 2) can be scratched with your fingernail, whereas rock salt (H = 3) is harder to scratch with your fingernail, if at all. Gypsum crystals have distinctive cleavage and halite crystals form cubes when free-growing.Most sedimentary rocks have a clastic texture, but some are crystalline. Rock gypsum (a.k.a. gyprock) is a chemical sedimentary rock. It is an example of an evaporite - it forms by the evaporation of water (usually seawater) and the precipitation of dissolved minerals. Rock salt & rock gypsum often occur together in evaporitic successions.Gypsum dissolves by a simple two-phase dissociation.

Which igneous rock, when weathered, could produce sediment composed of the minerals potassium feldspar, quartz, and amphibole? 1.1 Introduction. Gypsiferous soils are soils that contain sufficient quantities of gypsum (calcium sulphate) to interfere with plant growth. Soils with gypsum of pedogenic origin are found in regions with ustic, xeric and aridic moisture regimes (Nettleton et al. 1982). They are well represented in dry areas where sources for the calcium sulphate exist.
Sedimentation means settling from a fluid, either water or air.
