Selenite, satin spar, desert rose, and gypsum flower are four varieties of the mineral gypsum. Selenite or clear gypsum has a glassy (vitreous) luster, though not as well developed as other minerals. Its sheen, likened to moonlight, accounts for its name.Solution or karst caves are the most common type of cave. These caves form by a chemical reaction where groundwater dissolves the rock slowly. Karst caves form mostly in one of two types of rock: carbonates (limestone, dolomite, and marble) and evaporites (gypsum, anhydrite, and halite). Karst begins with rain.It is deposited from groundwater with sedimentary rocks such as shale or limestone. Gypsum also forms from low temperature hydrothermal fluids. It can form ...
The ambient sand that is incorporated into the crystal structure, or otherwise encrusts the crystals, varies with the local environment. If iron oxides are present, the rosettes take on a rusty tone. The desert rose may also be known by the names: sand rose, Sahara rose, rose rock, selenite rose, gypsum rose and baryte (barite) rose.

Gypsum (calcium sulphate dihydrate) is a naturally occurring mineral used in dentistry to fabricate models ( Figure 12.1a ), casts and dies ( Figure 12.1b ). Calcination is the process of heating the gypsum to dehydrate it (partially or completely) to form calcium sulphate hemihydrate. Plaster and stone are products of the dehydration process.
Quick Answer. Scientists use two approaches to date rocks and fossils. Relative age dating is used to determine whether one rock layer (or the fossils in it) are older or younger than another base on their relative position: younger rocks are positioned on top of older rocks. Absolute age dating (or, radiometric dating) determines the age of a ...A soda straw (or simply straw) is a speleothem in the form of a hollow mineral cylindrical tube. They are also known as tubular stalactites. Soda straws grow in places where water leaches slowly through cracks in rock, such as on the roofs of caves.

The core ingredient of all gypsum plasters is gypsum rock–hydrous calcium sulfate–which has a water content of about 20% in chemical combination. During processing, about 3/4 of this chemically combined water is removed from the gypsum rock employing a controlled heating process called calcination.Karst is a type of landscape where the dissolving of the bedrock has created sinkholes, sinking streams, caves, springs, and other characteristic features. Karst is associated with soluble rock types such as limestone, marble, and gypsum. In general, a typical karst landscape forms when much of the water falling on the surface interacts with ...Gypsum is a calcium sulfate containing product that provides both calcium and sulfate to the soil system. No change in pH can be expected from a gypsum application. The calcium in gypsum can replace sodium in sodic soils or aluminum where aluminum toxicity might be a concern.
