- Difference Between Quartz Calcite And Dolomite
Calcite will effervesce vigorously in contact with cold, dilute (5%) hydrochloric acid, while dolomite produces a very weak effervescence. These differences are often not significant enough to make a positive …

Dolomite is harder than calcite (Mohs hardness 4). It often has a light pinkish color, and if it forms crystals these often have a curved shape. It commonly has a pearly luster. The crystal shape and luster may reflect the atomic structure of the mineral, in which two cations of very different sizes place stress on the crystal lattice.

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.

Another difference from dolomite is that dolomite contains cloudy inclusions with iron oxides. Occurrence: Occurs in almost all rock types. It is the primary mineral in both marble and limestone. It occurs with dolomite, quartz, gypsum, barite, fluorite, pyrite, sphalerite, galena, chalcopyrite, danburite, stilbite, malachite, and azurite. Editors

Table of Contents Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks. Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO 3).Dolomites are mainly produced by the secondary alteration or replacement of …

Calcite has three perfect cleavages that form rhombic fragments, while gypsum only has one perfect cleavage and two less distinct cleavage directions so that, when broken, it tends to form less well-developed rhombs than calcite does. Dolomite: Dolomite crystals can be distinguished from clear gypsum crystals by their cleavage.

The inorganic C (IC) pool in soils includes predominantly carbonate minerals — calcite (CaCO 3) and dolomite (CaMg(CO 3) 2). Calcite is usually the dominant form in active pedogenic environments (Doner and Lynn, 1977). These minerals usually control the activities of Ca 2 + and Mg 2 + in soil solution, and occur in neutral to alkaline soils.
