Gypsum And Halite Are Formed By What Process

Gypsum - Wikipedia

Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins. Hydrothermal anhydrite in veins is commonly hydrated to gypsum by groundwater in near-surface exposures. It is often associated with the minerals halite and sulfur. Gypsum is the most common sulfate mineral.

Fluorite cleaves in four directions to form octahedrons, while halite has perfect cleavage in three directions to form cubes, so the cleavage planes of halite always form at right angles to one another. Halite has a distinctive salty taste and is softer than fluorite, being easily scratched by a fingernail.

Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporate during dry seasons, causing a recession in the water level and an increase of salinity content.

Identifying Calcite vs Gypsum

Feb 02, 2018 · I am looking for help from anyone who can assist me in the knowledge required to test for gypsum in my calcite.
