Gypsum [hydrous calcium sulfate, CaSO 4·2H 0] is the most abundant of the 150 sulfate minerals. It crystallizes in the monoclinic system as prisms and flat blades, and also occurs in massive and fibrous forms. It has a low density (specific gravity only 2.3), a vitreous luster, and perfect, one-directional cleavage.

Jarosite, found in sedimentary rocks by both the Curiosity and Opportunity rovers on Mars, precipitates out of water. Using CheMin, scientists are able to study further the role that water, an essential ingredient for life as we know it, played in forming minerals on Mars. For example, gypsum is a mineral that contains calcium, sulfur, and water.

Drywall is made of gypsum plaster and cellulose or fiberglass as its main ingredients. Drywall panels, also known as wallboard, plasterboard, gypsum board, or Sheetrock, are created by sandwiching a core layer of wet gypsum plaster between heavy paper or fiberglass surface sheets and then hardening them in drying chambers.

Much of the world's supply of iron comes from banded iron deposits that formed between 1.8 and 2.6 billion years ago. In addition to being a source of iron, why are these deposits important in geology? a.) mark the point in history when marine mammals were first beginning to evolve b.) provide evidence of the earliest known sedimentary rocks c.) …
"The minerals that are required for solar panels — which includes indium, iron, nickel, lead, copper — they're projected to increase in demand by 300 per cent through 2050," she said.
Gypsum is the common name for the mineral calcium sulfate, which has a chemical formula CaSO 4. Gypsum bonds easily with water and is usually found in its natural state as hydrated calcium sulfate, with a chemical formula of CaSO 4.2H 2 0. Gypsum is a soft mineral that usually appears white or gray and is composed of …
Gypsum has been used by smugglers to make a variety of objects, including hollow statues and figurines, with the intention of evading the scrutiny of customs inspectors. As a result of its high weight, low cost and widespread availability, 80 percent of gypsum is sold and consumed in the country where it is produced.
Gypsum is a hydrous, soft sulfate mineral, specifically a calcium sulfate dihydrate, which means it has two molecules of water in its chemical composition. This is seen in its chemical formula, CaSO 4 2H 2 0. When gypsum is heated and the water within the mineral is evaporated out, gypsum turns into a chalk or plaster, known as plaster of …

The Mohs Hardness Scale is a set of ten reference minerals (numbered 1 through 10) that are used to determine the relative hardness of minerals and other objects. In this test the hardness of a mineral is defined as its "resistance to being scratched". A list of the Mohs Hardness Scale Minerals is shown in the table below.
Selenite is incredibly soft compared to most minerals. It sits firmly at a 2.0 on the Moh's scale, which is softer than copper (3.0) or even your fingernails (2.5). This makes it unsuitable for jewelry. Selenite is …
