An adequate geochemical model of dolomitization requires a knowledge of the stability of dolomite. In theory, the equüibrium constant for the dolomitization reaction can be obtained by a variety of ways: (1) experimental study of equihbrium interaction between calcite, dolomite, and water, (2) calculation from thermodynamic data, and (3) study of the …
Dolomite is very similar to the mineral calcite or traditional marble. Calcite is composed of calcium carbonate (CaCO 3), while dolomite is a calcium magnesium carbonate (CaMg(CO 3) 2). The best way to tell these minerals apart is to consider their hardness and acid reaction. Calcite has a hardness of 3, while dolomite is slightly harder at 3 1 ...

Origins. Marble is a metamorphic rock resulting from regional or rarely contact metamorphism of sedimentary carbonate rocks, either limestone or dolostone, or metamorphism of older marble.This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite, aragonite …
Note that we refer in the title of this polemic to 'carbonatite-forming magmas' rather than the commonly used 'carbonatite magma' or 'carbonatite melt', as the actual composition of any calcite or dolomite carbonatite-forming magma is not known. Typically, many carbonatites appear to be rocks formed by crystal fractionation from a variety of …

Therefore, the thermal decomposition temperature of dolomite marble is 600 °C around, lower than calcite marble in previous references [16, 26]. At present, the mechanism of thermally induced decomposition of dolomite is still a matter of strong controversy. Generally, there are two different paths to represent the dolomite …

This process changes the composition, forming predominantly calcite or dolomite crystals, giving marble its distinct textures and patterns. It is available in a wide array of colors, including white, black, green, gray, yellow, and rose, depending on the mineral impurities present during its formation.
Marble - Building, Sculpture, Decoration: Marbles are used principally for buildings and monuments, interior decoration, statuary, table tops, and novelties.
