contact metamorphism in limestone and dolomite

contact metamorphism in limestone and dolomite deposits

• Limestone is a calcium carbonate mineral whereas dolomite is made of calcium magnesium carbonate. Skarns can form by regional, or contact metamorphism and therefore form in relatively high-temperature environments. Gold may occur along limestone-quartz contacts.

Metamorphism of Dolomites and Limestones SpringerLink

22/04/2011· There are two main types of carbonate rocks, dolomites and limestones. The first is modally dominated by dolomite (CaMg(CO 3) 2), the second by calcite (CaCO 3) and there is a complete gradation between the pure dolomite and limestone “end members” indicated by the rock names, calcitic dolomite, dolomitic limestone, magnesian limestone. As the rocks often also contain variable amounts of quartz they are sometimes referred to as siliceous dolomites and siliceous limestones.
