Is It Calcite or Dolomite? Rock & Gem Magazine
Aug 27, 2019· The minerals calcite and dolomite are chemically similar and actually form a series ranging from pure calcium carbonate calcite to pure calcium, magnesium, carbonate dolomite. The magnesium atoms that substitute for the calcium are a bit smaller than those of calcium, and this affects the appearance of many dolomite crystals.

Calcite and Dolomite University of Pittsburgh
Calcite and dolomite are very similar minerals. Both have the same hardness (H = 3), the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test: a drop of 1 M HCl on calcite produces an instant, obvious fizz; a drop on dolomite produces slow or no obvious bubbling.

Calcite-Dolomite UND
Epidote, Dolomite and minor Pholgopite in a Marble. This is a marble from Essex County, New Jersey. The twinned dolomite is clear (PP) and shows high order, almost white, interference colors (XP). Dolomite, like calcite, is one of the few minerals that shows twins in both PP and XP.

then moves into a soil horizon that con tains both calcite
If calcite dissolves much more rapidly than dolomite, calcite saturation would be attained much before dolomite saturation. After calcite saturation is reached, dolomite would continue to dissolve, but incongruently, until dolomite saturation is reached. The Ca 2 +/Mg 2 + molal ratio would evolve from a high initial value to a much lower value

Hydrothermal mineral assemblages of calcite and dolomite
Nov 27, 2020· The “phenocrysts” are composed of two types of mineral assemblages. The first is a coarse euhedral calcite assemblage in the Jimusar Sag, and the second consists of dolomite, analcime, and pyrite in the Shishugou Sag. The lithological and mineralogical features indicate a hydrothermal origin for these phenocryst-like minerals.

Mn 2+ appears to be the most abundant and important activator in natural calcite and dolomite. Substituting for calcium in both minerals, its emission is orange-red to orange-yellow, with a fairly broad band between 570-640 nm (maximum between 590-620 nm). The emission band maximum of Mn 2+ substituting for Mg 2+ (in dolomite) is located around

DOLOMITE (Calcium Magnesium Carbonate)
Dolomite differs from calcite, CaCO3, in the addition of magnesium ions to make the formula, CaMg(CO3)2. The magnesium ions are not the same size as calcium and the two ions seem incompatible in the same layer. In calcite the structure is composed of alternating layers of carbonate ions, CO3, and calcium ions. In dolomite, the magnesiums occupy
