But when most people think of a cave, they think of one like Onondaga, formed by chemical solution in carbonate rock. Limestone and dolomite are the most common carbonate rocks that form solution caves. Gypsum is another common mineral formed in carbonate caves by cave making processes, though it is uncommon in Missouri caves. Gypsum: Gypsum can also form translucent crystals and may be associated with calcite, but gypsum only has one very well developed cleavage plane, while calcite has three that form well-developed rhombs. Unlike calcite, gypsum does not react with dilute acid to form bubbles, although if the gypsum is crushed into a powder it may simply dissolve.Abstract and Figures. Contains 4 figures.

Rock gypsum (a.k.a. gyprock) is a chemical sedimentary rock. It is an example of an evaporite - it forms by the evaporation of water (usually seawater) and the precipitation of dissolved minerals. Rock salt & rock gypsum often occur together in evaporitic successions. Rock gypsum is composed of the mineral gypsum (CaSO 4 ·2H 2 O - hydrous calcium sulfate).Rock gypsum is a chemical precipitate formed by the evaporation of cencentrated solutions such as seawater.

Shell beds and ...Rock fragments in the gypsum are mostly variably altered dacite, with subordinate basalt and andesite. Analyses for elements that are incompatible in gypsum, and that have a high concentration in the inclusion phases (represented by a D-value significantly higher than the D-value of gypsum) are most susceptible to modification.Solution Caves. 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.The most common of these deposits contain beds of halite or gypsum. Rocks composed of these two minerals are found in many places. Halite deposits may be 1,000 m thick or more, but gypsum rock deposits are generally much thinner. Both kinds of deposits form during evaporation of inland seas or other isolated waters.
