Gypsum and Halite

Gypsum is readily identified by its softness (a fingernail scratches it). Gypsum comes as clear crystals that display one perfect cleavage (selenite) as blocks of featureless white rock (alabaster) and as silky fibrous blocks (satin spar). Halite (next page) breaks into cubes (three cleavages at

Sedimentary Rocks Lesson #13Volcano

When these crystals grow large enough to fill the spaces they harden and form a solid rock. Some non-clastic rocks are limestone chert dolostone gypsum halite (rock salt) diatomite and chalk. Organic sedimentary rocks form from the build up and decay of plant and animal material.

Properties and Uses of GypsumScienceStruck

Gypsum beds were formed due to the evaporation of water from the massive prehistoric sea basins. When water evaporates the minerals present in it become concentrated and crystallize. Gypsum is formed when due to evaporation sulfur present in water bonds with oxygen to form a sulfate. The sulfate then combines with calcium and water to form

It was the ancient Greeks who named this magic mineral "Gypsos" from which we have derived the name Gypsum. There is another form of gypsum which is clear and transparent in layers like mica. This was used many centuries before glass was invented as windows in the old temples.

EvaporitesUniversity of Kansas

Some of the Kansas evaporites were formed (and are still being formed) on land. Areas in northeastern Stafford County and near Jamestown in Cloud County form small salt (halite) flats. These are formed by groundwater erosion of gypsum and halite into a solution and then being redeposited at or near the top of the ground surface.

Sedimentary Rocks

Rocks formed in this way include halite gypsum anhydrite and some limestones. Layers of precipitated rocks are called evaporite deposits because they typically form where evaporation is high in arid regions like the desert southwest and in the eastern Mediterranean. Salt flats in the desert southwest and elsewhere contain vast deposits of

Sedimentary rockSedimentary rockEvaporites Evaporites are layered crystalline sedimentary rocks that form from brines generated in areas where the amount of water lost by evaporation exceeds the total amount of water from rainfall and influx via rivers and streams. The mineralogy of evaporite rocks is complex with almost 100 varieties possible but less than a dozen species are

Halite salt The mineral Halite information and pictures

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.
