Dolomite - Complete Mineral Overview
Dolomite is an anhydrous carbonate mineral composed of nominally equal parts calcium and magnesium, with the formula CaMg (CO 3) 2. Its chemical formula can be more clearly written as CaCO 3 .MgCO 3. Because of the presence of two various cations, which form regular layers inside dolomite structure, dolomite crystal symmetry is lower than calcite.

Dolomite (rock) - Wikipedia
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 65 million years in age).
Dolostone (Limestone)
Pure dolomite contains 54.28 percent calcium carbonate and 45.72 percent magnesium carbonate. Dolostone is commonly referred to by its mineral name, dolomite. Limestone is composed of material derived by both chemical and biological activities. The particles of sediment that make up a typical limestone are frequently recognizable as fossil ...
Dolomite – Virtual Museum of Molecules and Minerals
Dolomite. Dolomite is a calcium/magnesium carbonate mineral. It has a formula unit composition of CaMg (CO 3) 2. Dolomite has a trigonal crystal system with rhombohedral habit. In ideal dolomite, calcium and magnesium are separated into completed separate planes, quite unlike magnesian calcites in which Mg randomly substitutes for Ca.

Dolomite Mineral | Uses and Properties
Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.

Calculate Lime Application
First, determine your calcium:magnesium ratio. Use calcitic lime if the Ca:Mg ratio is below 7:1. Use dolomitic lime if the Ca:Mg ratio is above 10:1. If the Ca:Mg ratio is in between 7 and 10, look at the base saturation of Mg and Ca. If Ca saturation is below 65%, use calcitic lime. If Mg saturation is below 10 %, use dolomitic lime.
