Gypsum (CaSO 4 ·2H 2O) is one of the most common evaporite rocks, that is, inorganic rocks formed by chemical precipitation in a concentrated solution. As gypsum is much more soluble than limestone, it is much less common in outcrops. This is one of the reasons why gypsum karst has received relatively little appreciation in the past in the ...
Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates.

The three statements below are observations of the same rock sample: • The rock has intergrown crystals from 2 to 3 millimeters in diameter. • The minerals in the rock are gray feldspar, green olivine, green pyroxene, and black amphibole. • There are no visible gas pockets in the rock. 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. Lithified alluvial beds are the primary basin-filling rock found throughout the Basin and Range region of the western United States. The most distinctive alluvial sedimentary deposit is the alluvial fan, a large cone of sediment formed by streams flowing out of dry mountain valleys into a wider and more open dry area.Rock salt and Gypsum are typically formed by the evaporation of salty water.

Gypsum occurs in nature as flattened and often twinned crystals, and transparent, cleavable masses called selenite. Selenite contains no significant selenium; rather, both substances were named for the ancient Greek word for the Moon.
