Dolomite Mineral | Uses and Properties

Dolomite serves as the host rock for many lead, zinc, and copper deposits. These deposits form when hot, acidic hydrothermal solutions move upward from depth through a fracture system that encounters a dolomitic rock unit. These solutions react with the dolomite, which causes a drop in pH that triggers the precipitation of metals from solution.

Dolomite - Wikipedia

Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper.

What is the difference between dolomite and limestone? - Quora

Mar 26, 2018· Dolomite crystals are usually white or greyish pink in colour, yet the presence of certain impurities can bring a colour change; i.e. Iron in dolomite gives it a yellowish brown tint. Furthermore, metals such as Lead and Zinc can substitute magnesium in the mineral structure.

Zinc | Earth Sciences Museum | University of Waterloo

Calcium in calcite is replaced by magnesium forming the mineral dolomite. This reaction usually destroys fossils in the limestone and forms holes in the rocks, which are then good places where lead-zinc minerals may form. Brines flowing through other sediments such as shale may pick up lead and zinc …
