Flint is another type of rock that can resemble glass, and sometimes people will confuse this for obsidian.Gypsum is considered both a sedimentary rock and a mineral. Its chemical formula is CaSO 4 ∙2H 2 O. Because gypsum formed when ancient seas evaporated in Oklahoma during Permian time (299-251 million years ago), geologists classify it as an evaporite. Western Oklahoma has many large deposits of gypsum totaling trillions of tons (Figure 1).Karst is an area of land made up of limestone. Limestone, also known as chalk or calcium carbonate, is a soft rock that dissolves in water. As rainwater seeps into the rock, it slowly erodes. Karst landscapes can be worn away from the top or . dissolved from a weak point inside the rock.. Karst landscapes feature caves, underground …

Rock Gypsum is a chemical precipitate that is composed almost exclusively of the mineral gypsum. Gypsum commonly ranges in color from orange to light red and is characterized by the low mineral hardness of gypsum (Mohs hardness = 2). Gypsum forms from evaporation of seawater in a closed basin and arid environment.Drywall Sizes.
