2011-4-22  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.

2020-8-31  The metamorphism of siliceous dolomitic limestone is considered with the aid of a composition tetrahedron which suggests that the changes may be referred to thirteen steps or grades of increasing decarbonation, taking place at successively higher temperatures at any given pressure. At the temperature appropriate to each step a certain phase assemblage becomes unstable and each step is ...

Contact metamorphism of impure dolomitic limestone in

Progressive metamorphism of impure dolomitic limestone in the 1.5 to 2.5 km wide contact aureole surrounding the northernmost portion of the boulder batholith has resulted in a consistent sequence of uniformly distributed zones of low-variance mineral parageneses separated by abrupt and distinctive isograds. In silica-undersaturated, aluminous marbles, the following mineral assemblages occur ...

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.

Marbles are formed by regional, and less commonly thermal, metamorphism of relatively pure limestone and dolomite, and in general, metamorphism of relatively pure limestone and dolomite yields generally phaneritic marble and dolomite marble, or dolomarble, respectively.
