Several slope mines in the High Bridge originally were the site of open-pit quarries in the Lexington Limestone. After reserves of Lexington Limestone on the property were exhausted, an inclined slope was driven down into the underlying High Bridge limestone and dolomite to produce stone by underground mining.
LIMESTONE MINING Calcite and dolomite, when heated and in some cases slurried or combined with salt, are used in making many everyday products such as paper, glass, paint and varnish, soap and detergents, textiles, refractories, baking powder, and pharmaceuticals, including milk of magnesia and bicarbonate of soda.
• High-Calcium Limestone: Calcite > 95%, Other Rock Materials < 5% • Magnesian Limestone: Calcite 90–95%, Other Rock Materials < 5%. Lastly, some dolomites contain an excess of magnesium (Mg) and are called magnesian dolomite or high-magnesium dolomite. The excess magnesium is probably in the form of magnesium carbonate minerals, of which ...
Water moving through tiny cracks in limestone and dolomite slowly dissolves the rock and carries it away in solution. Through this process, large caves and caverns can develop in the subsurface. As rock is removed, the soil above washes into the void space.

Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.
