Dolomite is a sedimentary rock made mostly from the mineral dolomite and it''s also known as dolostone. Sometimes, showrooms will label Dolomite as "hard marble," and the reason for this is because it is denser than marble. Dolomite is porous, though not as susceptible to staining, etching and cracking as marble.

Comments. A carbonate mineral, dolomite forms a series with both the very rare ankerite, in which iron (Fe) exceeds magnesium (Mg), and the manganese (Mn)-dominant kutnohorite.Dolomites that contain Fe (but not in excess of Mg) are known as ferroan dolomites. Manganoan dolomites contain Mn, of course, which gives these stones a pink color.
DOLOMITE INFORMATION. Most minerals have a range of atomic structures with variable amounts of impurities and substitutions. Not so with Dolomite which has an unusual constant ratio between its content of MgCo3 and of CaCo3.

· Thus, the term dolomite describes a mineral series that encompasses a range of chemical variation and lattice structures. It encapsulates an array of natural Ca-Mg carbonates with chemical compositions close to ideal dolomite, but with weak or diffuse X-ray reflections that indicate varying degrees of cation disorder.
Dolomites, mountain group lying in the eastern section of the northern Italian Alps. The range comprises a number of impressive peaks, the highest of which is the Marmolada. The range and its characteristic rock take their name from the 18th-century French geologist Dieudonne Dolomieu. Learn more about the Dolomites.

Dolomite is an important rock-forming mineral that named is French mineralogist Déodat Gratet de Dolomieu. It is a colorless to white, pale brown, grayish, reddish, or pink mineral. Its crystals are commonly rhombohedral or tabular, often have curved faces, and sometimes cluster in saddle-shaped aggregates. Dolomite may be striated ...
Real ranch results show that Texas Range Minerals custom formulas are "proven on the scales". Our cattle minerals benefit cow-calf operators with quicker breed-up and heavier calves at weaning. Stocker operators using our livestock mineral see increased average daily gain and enhanced herd health.
The new found mineral later was named Dolomite in Dolomieu''s honour and later the whole mountain range received the same name. However, the assumption that the whole mountain range is made up from this kind of rock is wrong.
· The Dolomite stone is named after a French mineralogist, Dolomieu. It is a sedimentary rock which comprises of about 50% of the mineral dolomite in its weight. It develops in the underground of the mountains in Italy. One of the unique characteristics of dolomite is that, it does not bubble when subjected to acid.

Such rocks form vast deposits; in Italy, the Alpine range known as the Dolomites is almost entirely composed of dolomite. However, unlike calcite, dolomite''s sedimentary origin is enigmatic. Although it is the most stable carbonate mineral where magnesium is abundant in the marine environment, it is unknown as a primary mineral.
Dolostone is quite similar to limestone, but is composed mostly of the mineral dolomite (CaMg(CO3)2). Dolostone forms when magnesium in pore water is substituted for some of the calcium in the original limestone, or by direct precipitation.
