Gypsum - Wikipedia
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.

Volcanic soil - Soil that is derived from one of two volcanic activities. 1.) Vent-based soil is formed from rock material (including pumice and tuff) that has been ejected into the air and cooled before settling to the earth. 2.) Lava-based soil is the product of lava flows from the volcano. Ninety percent of lava-based soil is composed of,
Gypsum Mineral | Uses and Properties
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.
Anhydrite Mineral | Uses and Properties
Anhydrite also occurs as a vein-filling mineral in hydrothermal deposits. It is deposited from solution, often along with calcite and halite, as gangue in sulfide mineral deposits. Anhydrite is also found in the cap rock of salt domes.. Anhydrite is an anhydrous calcium sulfate with a composition of CaSO 4.It is closely related to gypsum, which has a chemical composition of

Further reading about soil types. Gelisols are soils that are permanently frozen (contain “permafrost”) or contain evidence of permafrost near the soil surface. Gelisols are found in the Arctic and Antarctic, as well as at extremely high elevations. Permafrost influences land use through its effect on the downward movement of water and freeze-thaw activity (cryoturbation)
How To Make Soil Drain Better (5 Ways To Fix Soggy Soil,
Sand, gypsum, and limestone are good additives to improve drainage if you have clay soil. Make sure to use coarse sand, since fine sand can lead to hard, compacted soil (sort of like concrete!). Gypsum (calcium sulfate) and lime (calcium carbonate) both help to improve drainage, in addition to providing extra calcium for your soil.

(3) it is a soil textural class. Many materials of the clay size fraction, such as gypsum, carbonates or quartz are small enough to be classified as “clay” on the basis of size but are not “clay minerals”. Sometimes some clay minerals have a size of 4 or 5 p (double the upper size limit of the “clay size fraction”).
