A limestone rich in magnesium carbonate, frequently somewhat crystalline in character. It is found in ledge formations in a wide variety of color tones and textures. Generally speaking, its crushing and tensile strengths are greater than the oolitic limestones, and its appearance shows greater variety in texture.
Limestone that contains more than ten percent but less than eighty percent of the mineral dolomite.
limestone that includes small amounts of the mineral dolomite.
Sometimes used when 'liming' soil that has an acid pH level that is too high. As it contains calcium and magnesium carbonate it should be used only with soils that are also deficient in magnesium as well. (See also Calcitic Limestone)
