Where does gypsum form.

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. Gypsum is a mineral that, on Earth, forms when sulfate- and calcium-rich salt water evaporates.

You cannot use gypsum plaster in the garden. Gypsum that is suitable for horticultural and agricultural use is straight gypsum. Gypsum plaster has additives that form hardness. It will not help the soil in any way. How long does gypsum take to break down clay soil? Gypsum will start working on clay soils straight away.★ When gypsum is heated, it loses water and gets converted to calcium sulfate hemihydrate, which is commonly known as ‘bassanite’. Further heating of this mineral produces anhydrous calcium sulfate or anhydrite. ★ ‘Selenite’ is one of the common varieties of gypsum, that occurs in nature in the form of flattened and twinned crystals ...What environment does gypsum form? Gypsum will form in any environment in which there is high evaporation of marine waters, and an absence of abandant clastic sediment to maske it. Sedimentary gypsum forms under high evaporative conditions in sedimentary rocks, both clastic and carbonate.[4] It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, drywall and blackboard or sidewalk chalk.[5] ...Selenite is the crystalline form of gypsum. These crystals are very brittle and fragile. Selenite can form large crystals—some as big as bicycle tires! Visitors to the park can see selenite crystals on hikes to Lake Lucero. There are three other varieties of the mineral gypsum: satin spar, desert rose, and gypsum flower.

It occurs in extensive beds associated with other evaporite minerals, particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite. Gypsum speleothems form because water seeping into the cave often contains small amounts of gypsum (calcium sulfate, CaSO4) picked up from the limestone or overlying sandstone. When this water evaporates in the cave, it deposits gypsum in the form of needles, beards, flowers, or spiders. Gypsum formations are found only in dry parts of the cave.The two main processes by which sediment is produced are: physical and chemical weathering. Lithifies can be defined as: loose sediment hardens into sedimentary rock. Mountain streams and rivers typically are characterized by: steep gradients and are confined by bedrock canyons. Fluvial refers to: the processes and sediment of streams and rivers. When water is added to either hemihydrate or anhydrite, these phases rehydrate to form gypsum in an exothermic reaction. Two phases of hemihydrate result when gypsum is dry or wet heated: α-hemihydrate and β-hemihydrate, each with distinct physical properties (Kelley et al., 1941). The α-hemihydrate is produced by wet heating (in a humid ...
