Gypsum is a delicate sulfate mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). It is commonly present in sedimentary rock formations and is often connected to other minerals which include anhydrite, halite, and sulfur.
Crystals of gypsum up to 11 m (36 ft) long have already been located in the caves of your Naica Mine of Chihuahua, Mexico. The crystals thrived during the cave's exceptionally scarce and secure normal environment.
The dunefield is nested from the Tularosa Basin, that is surrounded with the San Andres as well as the Sacramento Mountains. These mountains are made up of levels of gypsum. Rainfall and snowmelt from these mountains dissolve the gypsum and wash it all the way down to basin’s flooring. Below it's got nowhere to go, much like a bathtub or sink without drain. The water settles to the basin flooring at its cheapest position, named Lake Lucero. When weather conditions are best, the h2o evaporates, as well as dissolved minerals recrystallize and variety selenite crystals. Selenite would be the crystalline type of gypsum. These crystals are very brittle and fragile. Selenite can kind big crystals—some as major as bicycle tires! Guests on the park can see selenite crystals on hikes to Lake Lucero.
Gypsum is a standard mineral, with thick and comprehensive evaporite beds in Affiliation with sedimentary rocks. Deposits are known to occur in strata from way back to the Archaean eon.[sixteen] Gypsum is deposited from lake and sea water, and also gypsum in incredibly hot springs, from volcanic vapors, and sulfate solutions in veins.

Hydration of Anhydrite: Gypsum can also type in the hydration of anhydrite (CaSO₄). Anhydrite is really a calcium sulfate mineral that lacks the drinking water molecules existing in gypsum. When exposed to drinking water, anhydrite undergoes a hydration reaction, incorporating water molecules into its composition and remodeling into gypsum.
Drywall is made from gypsum blended with Portland cement powder. It makes it a lot more proof against water injury than gypsum by itself. Drywall is also far more resistant as the gypsum is involving two thick paper sheets.
Gypsum also takes place in crystal variety, Together with the two most frequent kinds becoming huge crystal clear crystals that in many cases are termed selenite, and fibrous crystals, referred to as satin spar. ‘Selenite’ is definitely the Greek word for moon, and refers to the crystals effectively-created pearl-like luster that can replicate a delicate moon-like glow. In arid sandy regions, expanding gypsum crystals may perhaps bind sand grains with each other into complicated clusters referred to as ‘desert roses’.
Drywall is more versatile than gypsum. You may use it for inside and exterior walls and ceilings. Gypsum is barely suited to interior partitions.
It’s a fibrous material that may be cut, sanded, and textured to produce an inside wall surface area. Drywall’s Houses ensure it is a fantastic option for interior wall and ceiling finishes.
Salt Flats: Gypsum is a common component of salt flats, that are expansive, flat places by using a salt crust about the surface area. These salt flats generally sort in arid locations the place water flows into depressions after which evaporates, abandoning the salts, which include gypsum.
Gypsum formations is often really breathtaking, building otherworldly landscapes and dazzling cave attributes. Below are a few popular gypsum formations around the world:
Utilizing drywall or gypsum in the development venture depends upon your Tastes and in which you’re installing it. If sturdiness is the principal Consider your undertaking, you'll be able to opt for gypsum. Take into account that gypsum desires Expert installation. So, it might cost you much more In the long term.
