2020-1-1 · Mineral chemical analysis on the syn-ore hydrothermal calcite from Tongjiachong suggests that all the calcite samples are enriched in rare earth elements and yttrium (REYs) (ΣREY = 53.7–119.9 ppm). They have similar Y/Ho (38.3–42.3) and varying La/Ho (21.8–86.7), and display consistent convex PAAS-normalized REY patterns.

White Field Minerals, Kochi

It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits ofbase metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel.

Is It Calcite or Dolomite? | Rock & Gem Magazine

2019-8-27 · When cobalt replaces calcite, it gives the mineral a lovely pink color, and we call it cobaltocalcite. Cadmium can substitute in smithsonite, giving it a nice yellow color. Dolomite crystals do not develop as often as calcite, which is by far the most abundant carbonate mineral. But dolomite does form fine crystals that can be very showy.

Dolomite

2019-3-23 · Dolomite is an anhydrous carbonate mineral composed of nominally equal parts calcium and magnesium, with the formula CaMg (CO 3) 2. Its chemical formula can be more clearly written as CaCO 3 .MgCO 3. Because of the presence of two various cations, which form regular layers inside dolomite structure, dolomite crystal symmetry is lower than calcite.

Calcite, Aragonite, Dolomite, Marble

Dolomite is both a mineral and a rock. The mineral is the pure form, and Dolomite rock is composed mostly of Dolomite, but also with impurities such as Calcite, Quartz, and Feldspar. It is named for the French mineralogist, Deodat de Dolomieu. Though harder than Calcite, Dolomite also is a fairly soft stone-about a 3.5 to a 4.
