Physical Characteristics of Limestone | Sciencing

Apr 25, 2017· Limestone is a collective term for a group of sedimentary rocks that consist of at least 50 percent calcite, a mineral formed of calcium carbonate. If some of the calcium becomes replaced by magnesium, the resulting calcium magnesium carbonate rock is called dolomitic limestone. ... Physical Characteristics of Limestone

SELECTED CHARACTERISTICS OF LIMESTONE AND DOLOMITE ...

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, there is a statistical tendency for carbonate reservoirs to occur preferentially in dolomites.

Weathering of Limestone ia Department of Education

If a home is built with limestone bricks and nonlimestone bearing mortar to hold the home together, what does this mean for the weathering rates of the two materials? o Looking specifically at our nation's capitol, why would so many of the monuments and buildings be constructed of limestone if it will eventually weather away?

The limitations of these calibration methods are essentially linked to the representative nature of the cores used during calibration. A comparison of the results obtained by electromagnetic methods with electric resistivity or capacitive methods can enable trends to be checked for similar results.
