The blades are lightly striated and beneath shows the point of attachment around what appears to be a small sulphide or sulphosalt mineral embedded in the Calcite. Those faces of the Calcite rosettes with a specific orientation are completely coated with micro-crystals of pearly cream Dolomite.

Members of this group have a crystal structure similar to that of calcite dolomite alternate Ca positions are occupied by Mg these becoming structurally non-equivalent and the crystal point symmetry being lowered from 3 2/m to 3.

Feb 18 2020 · The mineral is similar in many respects to calcite or calcium carbonate (CaCO 3) which also forms rock deposits — limestone and chalk — or crystals. Like limestone dolomite has some solubility in water especially if the water is slightly acidic and can form caves with stalactites stalagmites and other typical limestone features.

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 s symmetry class is bar 3 whereas the Calcite Group s symmetry class is bar 3 2/m. The loss of symmetry allows only simple crystal forms to be used by the Dolomite Group minerals mostly rhombohedrons. Dolomite is a very common mineral and ankerite is much more scarce. The other members are considered rare to very rare.

Dolomite Dolomite is the name of a sedimentary carbonate rock and a mineral both composed of calcium magnesium carbonate camg (CO3)2 found in crystals.Limestone that is partially replaced by dolomite is referred to as dolomitic limestone.
