The Silurian dolomite aquifer is used for water supply in much of a 14-county area bordering Lake Michigan in eastern Wisconsin. Because of the rapidity of ground-water movement, the aquifer is susceptible to contamination by waters percolating downward from surface sources.

Patches of dolomite occur in cores of reefal limestone from the shallow subsurface on the northeastern coast of the Yucatan Peninsula. This limestone accumulated during an interglacial high stand of sea level about 200,000 years ago. Dolomitization was preceded by freshwater diagenesis, including precipitation of sparry calcite cement, stabilization of …

Little Falls dolomite (restricted) thus represents and offshore, more carbonate phase of the aforementioned formations. Absence of these formations within Mohawk Valley further corroborates this interpretation; wherever exposed, the Little Falls rests directly on the Precambrian.

Dolomite is a sedimentary rock commonly interbedded with limestone, which extends over large areas of the United States. Most dolomite occurrences are likely the result of replacement of calcium by magnesium in preexisting limestone beds. Magnesite is 1Magnesium Commodity Specialist, MS 983, U.S. Geological Survey, Reston, VA. 3
Magnesium (Mg) is the eighth most abundant element and constitutes about 2% of the Earth's crust, and it is the third most plentiful element dissolved in seawater. Although magnesium is found in over 60 minerals, only dolomite, magnesite, brucite, carnallite, and olivine are of commercial importance.

Dolomite is the name for a mineral composed of calcium magnesium carbonate (CaMg(CO 3) 2) and for a sedimentary rock that has this mineral as its chief constituent. The rock was given this name first, but to avoid confusion it is sometimes known as dolostone.The pure mineral is white, but traces of impurities can give it a range of colors, including pink, …
