Ohio dolomite

Most of the kinetic measurements were made with a Virginia dolomite, whose analysis is given in Table III. Some measurements were made with an Ohio dolomite from the Greenfield formation. The two stones showed similar kinetic behavior. 

The South Dakota dolomite showed a lower but not vastly different activity from the Ohio dolomites. Finally, the South Dakota limestone showed an activity substantially below that of the dolomites. The C02 capacity of the limestone after 30 cycles is, however, equivalent to that of the best dolomite on a unit weight basis since the absence of the MgO diluent compensates for the lower activity. Therefore, limestone is equally useful an acceptor as dolomite in the process.

The Rose Run Sandstone is the best characterized of the Cambrian sandstones because it is also an oil and gas reservoir (Fig. 3). It is also the only one of the Cambrian sandstones that is known to retain its sandstone composition in the eastern part of the state rather than passing laterally into carbonate. The Rose Run Sandstone is a sandy layer in the middle of the Knox Dolomite (Fig. 4), which across much of eastern Ohio lies at depths suitable for injection of supercritical C02 (Fig. 3). The Rose Run Sandstone was deposited in a passive margin phase of the Appalachian Basin and consists of interbedded layers of carbonate, primarily dolos-tone, and sandstone (Fig. 5). The sandstone is compositionally mature, consisting largely of quartz. Subordinate reactive minerals are the alkali feldspars and locally abundant glauconite (Fig. 5). Dolomite and quartz are the dominant cements (Janssens 1973 Riley et al. 1993).

The lower unit of the Ohio Shale which is present in the outcrop area of eastern Kentucky is the Huron Member. Primarily, the Huron consists of black to brownish-black to gray-black, laminated, siliceous, OM-rich shales. Calcareous laminae, cone-incone limestone, dolomitic gray shales, dolomite beds and biotur-bated greenish-gray shales occur as interbeds and laminae in the lower parts of the member. Pyrite occurs as framboids, nodules, and irregular forms. 

Various acceptor materials had been assessed on both these points previously in which the reaction cycle was simulated in batch equipment (2). Various stones were tested, and the following conclusions were tentatively reached. Limestones and dolomitic limestones were unsuitable, owing to a rapid deactivation. Many pure dolomites were not suitable because of poor physical strength. Of the dolomites tested that showed good physical strength, the stones from the Greenfield formation in Ohio showed the best resistance to chemical deactivation. 

Commercial deposits of dolomite are found in many regions of the planet. The most important U.S. deposits of dolomite and dolomitic limestone are located in northwestern Ohio, New York, Connecticut, California, northwestern Pennsylvania, Missouri, Texas and Kansas. Important offshore deposits are found in England and Germany. The compositions shown in the table are typical.
