Frederick L. Schwab, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 IV.D Dolomite and Dolomitization. In many ancient limestones, the minerals calcite and aragonite have been partly or completely replaced by the mineral dolomite, producing replaced by the mineral dolomite, producing the rock dolostone (or traditionally, the rock dolomite).
Dolomite is an important rock-forming mineral that named is French mineralogist Déodat Gratet de Dolomieu. It is a colorless to white, pale brown, grayish, reddish, or pink mineral. Its crystals are commonly rhombohedral or tabular, often have curved faces, and sometimes cluster in saddle-shaped aggregates. Dolomite may be striated ...

Stone Corral Dolomite. Photo courtesy William C. Johnson. The mineral dolomite is the main component of the sedimentary rock that is also called dolomite.It is similar to the mineral calcite but contains magnesium as well as calcium. Just based on looks, the rock dolomite is often impossible to distinguish from limestone, which is composed mainly of calcite.

Kona Dolomite is an ancient rock in which formations of fossil stromatolite (blue-green algae) occur. The stone is between 2.1 to 2.2 billion years old. These stromatolite formations are from some of the first life on earth. These fossil formations are found in the lower eras of the Middle Precambrian Period.
AM2+(CO3)2. A = Ca, Ba. M = Fe 2+, Mg, Mn, Zn. Name: 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. Dolomite is a calcium/magnesium carbonate mineral. It has a formula unit composition of CaMg (CO 3) 2. Dolomite has a trigonal crystal system with rhombohedral habit. In ideal dolomite, calcium and magnesium are separated into completed separate planes, quite unlike magnesian calcites in which Mg randomly substitutes for Ca.
