  • Dolomite: The mineral dolomite information and pictures

    Dolomite is a very common mineral, and is known for its saddle-shaped curved crystal aggregates. A unique, isolated Dolomite occurrence in Eugui, Spain has provided colorless transparent crystals that resemble the Iceland Spar variety of Calcite.Dolomite Group: Mineral information, data and localities.,After the principal species in the group. Members of this group have a crystal structure similar to that of calcite. In 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.

  • Dolomite Mineral and Healing Properties

    Dolomite is a common sedimentary rock-forming mineral that can be found in massive beds known as dolomites. These beds may be several hundred feet thick. Dolomite also forms as sediments in ore veins such as limestone. Limestone where dolomite is present in more than a small amount are called dolomitic limestone.Rocks and Minerals, Kentucky Geological Survey, University,Dolostone is a sedimentary rock composed chiefly of the mineral dolomite, which is magnesium calcium carbonate. It is closely related to limestone, both physically and chemically; in fact, when the magnesium content decreases, it is often referred to as magnesian or dolomitic limestone.
