Karst is known at least locally and sometimes quite extensively in almost all areas underlain by evaporites, and some of these karst features involve significant subsidence. It outcrops in the valley of the North Fork of the Holston but is largely covered by the terrace and flood-plain deposits of that stream. Louis Limestone in northwestern Kentucky. The wells on the southeast side are wet and the brine flows in as fast as it is pumped out. This must be inferred from such facts as can be gathered in the mines, on the surface, and in the well records.
The processes by which salt-dome cap rock forms is a special type of salt dissolution; as salt rises in diapirs, ground water dissolves the upper surface of the salt and there is an accumulation of residual, relatively insoluble anhydrite and calcite as the cap rock Walker ; Kreitler and Dutton Processes of evaporite dissolution Processes for the development of karst and subsidence features in evaporite rocks are identical to those in limestone and dolomite, except that the processes are much more rapid. Whether workable beds will be found asso- ciated with all the gypsum deposits can not at present be determined, but where salt has not been encountered in mining the gypsum there is still a prospect that it may be discovered at greater depth close to or under the overthrust dolomite. Synthetic Anhydrite Hydrofluoric acid is produced using fluorite and sulfuric acid.
George, in southwest Utah Gourley ; Payton Depending upon the materials employed the period of hydration of bodies made according to this invention may vary from 2 days to days. The four basic requirements for evaporite dissolution to occur are: 1 a deposit of gypsum or salt; 2 water, unsaturated with CaSO4 or NaCl; 3 an outlet for escape of dissolving water; and 4 energy to cause water to flow through the system. Louis anhydrite interval is 62 ft 19 m thick. The gypsum and salt deposits of southwestern Virginia described in this report are believed by the writer to have been derived from calcareous- argillaceous sediments which originally contained disseminated gypsum and salt precipitated in a partly inclosed arm of the sea during the deposition of the Maccrady formation, these minerals having been con- centrated in the same formation by ground waters which circulated along the fault contact between the Carboniferous and Cambrian rocks, dissolved the calcium carbonate from the earthy limestones, and segregated the gypsum and salt in the gypsiferous and saline beds by chemical selection. Two industries associated with local salt dissolution and subsidence or collapse are the solution-mining and petroleum industries.

Note scattered lithoclasts arrow. Scale, double the scale of figure 5. Some of the calcite-filled tubes are divided by thin micritic walls. Wilder, president of the Southern Gypsum Co. Maiklem et al. Generalized section of a well at Saltville, Va. Stratification types differ between the two quartzose grainstone intervals.
No outcrops are visible in the broad flat at Saltville, but the absence of hard outcropping strata and the record of only soft rocks of Maccrady type in the deep wells at this place indicate that the syncline is followed on the east by an anticline whose east limb carries the Price sandstone below the points reached by the drill but apparently not deep enough to bring the Newman limestone down to the surface, so on the sections the rocks are shown to be undulating in the portions under cover of the overthrust fault.
The huge sink was apparently caused by accidental penetration of a large, active salt mine m below the surface by an oil rig that was drilling in a shallow lake. Cooper also pointed Gypsum and anhydrite deposits in southwestern Indiana. book that because gypsum dissolution is so rapid pumping large volumes of gypsiferous water from wells means that subsurface gypsum will be dissolved at an accelerated rate, and this can cause increased subsidence and possible collapse.
Human-induced subsidence in gypsum Gypsum karst and subsidence can be accelerated by human activity. Neal Fig. No fossils of any sort have been found 'thus far in the gypsum, its incasing red clay, or in the overlying blue clay; but just west from Saltville a conglomerate cemented by gypsum occurs, in which remains of Mastodon have been found ; this overlies the blue clay and incloses many fragments of both blue and red clay.
The smaller holes have fallen in and been filled up, but some of the larger ones are full of water and are reported to be very deep. The softer shaly limestones beneath are mashed and altered by circulating waters to clay adjacent to the fault.

Table Comparison of eolian and subaqueous grainstones based largely on Hunter, These rocks occupy the north- western portion of the mapped area and form the slopes of Clinch Mountain, which is capped by the basal Silurian formation, the Clinch sandstone, of Medina age.
In at least two localities branches protrude from the main body into drains or ravines, so that the horizontal plan resembles somewhat the splash made by throwing soft mud against a wall.

Natural subsidence in salt Salt deposits underlie a portion of 25 of the 48 contiguous states Fig. This is especially true southwest of Saltville, aHarris, G. He notes that dissolution of gypsum beds within the predominantly limestone sequence during Late Mississippian—Early Pennsylvanian time enhanced contemporaneous development of sinkholes, caves, dissolution-enlarged joints, and breccia zones.
Gypsum consists of calcium, sulfur and water while anhydrite consists of calcium, sulfur and oxygen. Figure Quartzose grainstone from the Mobil 1 Foster.
Geological Survey Hull. Salt deposits of central and southeast Utah have undergone diapiric movement and dissolution. Nodules are generally ellipsoidal and irregularly arranged. Because only planar-e dolomite crystals are present in chert, this indicates chertification postdates planar-e dolomite crystallization and predates planar-s and nonplanar dolomite crystalfization.The site was first discovered in The U.
S. Gypsum Company Mine was closed at the time of data entry with no known plans to re-open. Past operations took place since The ore mined is composed of gypsum with waste material consisting primarily of biotite and anhydrite.
