Mining Greece Marble

Marble is a rock that consists of calcite (CaCO3), or of the combination of calcite minerals (CaCO3) and dolomite ( (Ca,Mg) (CO3)2) and has been created by the metamorphism of limestones, that is of carbonate sedimentary rocks. The word's origin is the ancient Greek work "marmaros", which means "shiny stone". The use of marble had ...

DOLOMITE CaMg(CO - A. E. Seaman Mineral Museum

consist of calcite, variety "anthraconite." It has now been shown that the chief mineral is a ferroan dolomite (Wardlaw and Long, 1982). This dolomite forms long, slim, brown, prismatic crystals in subparallel to semi-radial patterns. The concretions are rimmed by 1 to 2 cm of pyrite, and the percent of dolomite decreases from their center

The Difference Between Dolomite and Marble | Cosmos Surfaces

Dolomite ranks higher than marble on the durability scale, largely due to its dense mineral composition. Slightly hHarder than most marbles, dolomites tend to resist scratches and heat more readily. However, this stone is not quite on par with the density & durability of granite and quartzite. In other words, it's a good middle-of-the-road ...

ALEX STREKEISEN-Diopside Marble-

The majority of marbles are dominated by calcite and/or dolomite (marbles dominated by dolomite are termed dolomarbles). 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 ...

Lazzarini (1987) referred to fine-grained dolomitic marbles from Crevola in Italy (today sold under the trademark Pallisandro) and also at Drama in Eastern Macedonia, and argues that these sources for dolomitic marble were of very limited importance if at all used in antiquity. Barbin et al. (1992) report about the occurrence of dolomitic ...

The maximum XMgCO3 value of 0.111 yields a solvus temperature of 698 °C. If this Mg-calcite formed from aragonite + dolomite, solvus thermometry gives a minimum P-T point along the equilibrium curve of the reaction aragonite + dolomite = Mg-calcite during the decompressional stage; T = 680 °C and P = 1.9 GPa.

Mad About Marble: A Geological Look at a Classic Stone

Marble with magnesium = Dolomite. Dolomitic marble is a close relative of regular marble. Standard marble is made of calcite (CaCO 3), and dolomitic marble has a little magnesium in the mix (CaMgCO 3). There is not a huge difference between the two variations, except that dolomitic marble is a little bit slower to etch.

Before magnesite was totally consumed, the P-T conditions changed and reached reaction (6), where omphacite reacted with dolomite to form calcite and Tr-Ab symplectite. Consistent Mg content of this calcite ( X M g ∼ 0.06) coexisting with Tr-Ab symplectite supports this model that the calcite around dolomite was formed at amphibolitization.

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 66 million years in age).

as is apparent from the properties of calcite and dolomite: when a drop or so of dilute hcl is placed on limestone or calcite marble, a vigorous effervescence occurs, whereas when a drop or so of dilute hcl is placed on dolostone or dolomite marble, it causes at most only a slowly smoldering/simmering effervescence (in fact, some dolostone and .
