Gypsum Mineral Uses and PropertiesGeology
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.

Glad You Asked How Do Geologists Identify Minerals
The color of the streak left by the mineral is sometimes different from the color of the mineral itself. A streak test comes in handy when identifying minerals such as hematite. Hematite can be found in various colors from black to red but it always leaves a red streak. Hardness. Hardness is a measure of a mineral s resistance to abrasion.

Physical Geology 1403 Characteristics/Properties of a mineral
The difference between cleavage and fracture is that cleavage is the break of a crystal face where a new crystal face is formed where the mineral broke whereas fracture is the "chipping" of a mineral. All minerals exhibit a fracture even those that exhibit cleavage.
