Dolomite rock Wikipedia,Dolomite is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. In old USGS publications, it was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolomites or magnesium-rich limestones. Dolomite has a stoichiometric ratio of nearly equal amounts of magnesium and calcium. Most dolomites …

The first geologist to distinguish limestone from dolomite was Belsazar Hacquet in 1778. Whinstone is a term used in the quarrying industry to describe any hard dark-coloured rock. Examples include the igneous rocks, basalt and dolerite, as well as the sedimentary rock, chert. Description: Massive outcrops of whinstone occur include the Pentland Hills, Scotland and the Whin Sills, England. The ...

Limestone is a sedimentary rock that is composed primarily of calcite (calcium carbonate, CaCO 3) and dolomite (calcium magnesium carbonate, CaMg(CO 3) 2). It can vary in purity, consistency and hardness. The limestone can be a soft chalky material with microfossils, a hard recrystallized mass, a grainy sand-lime mass, or a mass of fossil corals, urchins and shells.
