The main difference between dolomite and limestone is their mineral composition. Limestone mostly consists of calcium carbonate, while dolomite is a mixture of calcium magnesium carbonate. Another key difference between the two rocks can be seen in their appearance. Limestone tends to be light-colored, ranging from white to gray or …
Vein deposits of dolomite occur with quartz and other common vein minerals, such as calcite, magnesite, fluorite, siderite, and sphalerite, or with metallic ore minerals such as galena, pyrite and chalcopyrite. Although uncommon, when dolomite occurs in altered ultramafic igneous rocks, it may be associated with magnesite, serpentine, and talc.
Abstract. Damage to structures and loss of life have been more severe on dolomite than on any other geological formation in southern Africa. The subsidence that occurs on dolomitic terrain following development or during dewatering has given dolomite a notorious reputation and engineers and geologists became reluctant to recommend development ...
