Karst Aquifers

Karst terrain is created from the dissolution of soluble rocks, principally limestone and dolomite. Karst areas are characterized by distinctive landforms (like springs, caves, sinkholes) and a unique hydrogeology that results in aquifers that are highly productive but extremely vulnerable to contamination.

Carbonate rocks (limestone and dolomite) are the most common bedrock aquifers in the region (). Natural processes may increase permeability by dissolving carbonate minerals in these aquifers, but this increased permeability makes the aquifers more vulnerable to contamination.

USGS High Plains Aquifer WLMS: Generalized geology and …

The average groundwater flow velocity in the High Plains aquifer is about 1 foot per day ( Gutentag and others, 1984). Depth to water is the difference between the altitude of land surface and the altitude the water table. The generalized depth to water in the High Plains aquifer in 2000 ranged from land surface to more than 300 feet below land ...

About: Limestone

In old USGS publications, dolomite was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolomites or magnesium-rich limestones.

Both limestone and dolomite are important from an economic standpoint in the Birmingham district. Limestone is used for lime and cement, and both limestone and dolomite are extensively utilized as flux in iron smelting. Indeed, this fluxing material is one of the three essential factors in the great industrial development of the Birmingham district, coal and iron, of course, being the other two. Along …

SELECTED CHARACTERISTICS OF LIMESTONE AND DOLOMITE RESERVOIRS IN THE UNITED STATES.

Limestone reservoirs are more numerous in the United States than dolomite reservoirs (by a ratio of about 3 to 1) because limestones are more abundant than dolomite. However, in the eight states that account for over 90% of United States carbonate reservoirs ...

The Boyle Dolomite in Kentucky has also been called the "Corniferous" Limestone, the Onondaga Limestone, and the Hamilton Limestone. The New Albany Shale is an organic-rich black shale that contains thin beds of greenish-gray shale in two zones, one near the top and the other near the base.

Sinkholes

 · Dissolution of the limestone or dolomite is most intensive where the water first contacts the rock surface. Aggressive dissolution also occurs where flow is focused in preexisting openings in the rock, such as along joints, fractures, and bedding planes, and in the zone of water-table fluctuation where groundwater is in contact with the atmosphere .

Limestone—A Crucial and Versatile Industrial Mineral Commodity

Magnesium in ground water may convert some or all of the cal- cite in the limestone to dolomite. Also, some rocks formed near the shores of ancient seas in arid climates were mostly dolomite at the time they were deposited. Limestone comes in many different varieties.

What is Dolomitic Limestone? (with pictures)

Dolomitic limestone is a type of rock that includes up to 50% dolomite. Normal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions — this process is called dolomitization. This type of rock was once referred to as magnesian limestone ...
