regional metamorphism of dolomite and limestone

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.

Contact Metamorphism of Dolomite and Calcite limestone Dolomitic and calcitic limestone sediments may also be metamorphosed by adding heat from an igneous heat source at shallow levels in the crust. Commonly, the intrusive body is of granitic, granodioritic or quartz-dioritic composition and the temperature at the contact to the country rocks is in the order of 600-700 °C.

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).

Limestone and its magic! - ZEALmetal

Limestone is partially soluble, especially in acid, and therefore forms many erosional landforms. These include limestone pavements, pot holes, cenotes, caves and gorges. Such erosion landscapes are known as karsts. During regional metamorphism that occurs during the mountain building process, limestone recrystallizes into marble.
