Satin Spar Gypsum A fibrous variety of Gypsum. See also the main page on Satin Spar. Selenite The name 'selenite' is mostly synonymous with gypsum but has been used historically to describe the transparent variety, as opposed to satin spar gypsum for the fibrous variety and alabaster for the fine-grained massive form.

10(f) Characteristics of Sedimentary Rocks

The classification of clastic sedimentary rocks is based on the particle types found in the rock. Some types of clastic sedimentary rocks are composed of weathered rock material like gravel, sand, silt, and clay. Others can be constructed from the break up and deposition of shells, coral and other marine organisms by wave-action and ocean currents.

SEDIMENTARY ENVIRONMENTS AND FACIES

Some sedimentary minerals are strongly indicative of specific environments. Evaporite minerals such as halite (in rock salt) or gypsum (in rock gypsum) indicate deposition in hot dry settings where ion-rich water can evaporate to the point of precipitating the minerals.
