A completed sedimentation process results in the formation of limestone. If the sedimentation process takes place in water containing magnesium, dolomitization may occur. Part of the calcium ions ....

Standard interpretation is the process of determining volumes of hydrocarbons in place from wireline logs, or log interpretation. This process requires four basic steps: Determine the volume of shale. Shale affects the response of the various logging devices. To interpret the response for porosity or saturation, the volume of shale …Limestone is a rock that is composed primarily of calcium carbonate. It can form organically from the accumulation of shell, coral, algal, and fecal debris. It can also form chemically from the precipitation of calcium carbonate from lake or ocean water. Limestone is used in many ways.Dolomite, also known as " dolostone " and " dolomite rock ," is a sedimentary rock composed primarily of the mineral dolomite, CaMg (CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar ...

The CO 2-H 2 O fluid can have profound effects on the carbonate nearby, and fluid composition controls the formation of many minerals. Fluids may also cause significant metasomatism ... Limestone can be formed as a result of evaporation, as is the case for stalactites and stalagmites in caves, or through the accumulation of calcium carbonate in marine environments.

Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone.

Tin Mountain Limestone 1,000 feet (300 m) thick, is black with thin-bedded lower member and thick-bedded upper member. Unnamed limestone formation, 725 feet (221 m) thick, consists of interbedded chert and limestone in thin beds and in about equal proportions. Mixed brachiopods, corals, and crinoid stems.Most caves are formed when groundwater dissolves limestone. The development of most caves begins in the zone of saturation just below the water table as groundwater infiltrates the cracks and joints of limestone formations, it gradually dissolves the adjacent rock and enlarges these passages to form an interconnected network of openings.
