Gypsum rock type.

Rock material properties that are essential in assessing hydraulic erodibility of rock include rock type, color, particle size, texture, hardness, and strength. Seismic velocity, weathering, and secondary cavities are prop-erties related to both the rock material and mass. Rock material properties can be described in the field usingGypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks.

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).

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.

Glassy or Vitreous Luster in Selenite. 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.Although there is not a specific rock that is magnetic, certain magnetic properties of a rock may be found in the crystals and minerals that make up a rock. The magnetic mineral magnetite is commonly found in igneous rocks.economic natural resources involve sedimentary rocks. Resources such as coal, oil, natural gas, gypsum, aggregate (sand and gravel), and salt are all found within sediments. Sedimentary Structures . Sedimentary structures such as stratification (layering), ripple marks, cross-bedding, and mudcracks can be preserved in sedimentary rocks. 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.Limestone is a relatively soft rock with a Mohs hardness of 3, which means it can be easily scratched. It has a specific gravity of 2.7-2.9, which makes it less dense than most other rocks. It is typically soluble in acidic solutions, which is why limestone landscapes often feature caves, sinkholes, and other karst formations. Type of Limestone

Gypsum is a mineral commonly found in Kansas. When salty seawater evaporates, dissolved salts, including the mineral gypsum, are left behind. If conditions are right, large quantities of gypsum build up into thick beds of sedimentary rock. The gypsum throughout the state was deposited during the Permian, when an arm of the inland sea was cut ... The most common variety of gypsum is massive or rock gypsum. It consists of an intimate intergrowth of small crystals, and ranges from finely granular to coarsely crystalline in texture. It is widely distributed as a sedimentary rock interstratified with limestone and shale.
