dolomite

A general term for a specific form of calcium-magnesium carbonate that may used as a calcium supplement to ensure healthy bones, which is mined in the Dolomites in northeast Italy. Some of the mineral deposits are contaminated with heavy metals (lead, cadmium, etc.), for which the FDA sets a maximum level of 5 ppm (which dolomite exceedes).

dolomite

a limestone with a high concentration of magnesium. Used as a mineral supplement for animals. Called also dolomitic limestone.

Some of the diagenetic processes were also observed in the formation, including compaction, cementation, dolomitization and bioturbation.

The process of dolomitization has largely destroyed primary textures as well as fossils.
Carbonate diagenesis includes such major processes as cementation, microbial micritization, neomorphism, dissolution, compaction, and dolomitization and it operates in three main environments: marine, near-surface meteoritic, and burial (Tucker & Wright 1994).
The mineralization process (ore development, calcitization, dolomitization and silification) resulted in the higher toughness of the rocks and in the lower porosity and absorbability.
Ore in the Los Lamentos district is associated with dolomitization of limestone, the dolomite forming aureoles averaging 15 meters in thickness which in some cases surround the ore.
However, heterogeneities in the substrate, made by bioturbating infauna, may play a more important role in dolomitization than has been previously considered.
Four phases of dolomitization are recognized at Lisheen.
Dolomitization of the Wabamun is clearly associated with faulting at Saddle Hills and it is expected the case will be the same at Woking.
Grain fracture porosity and dolomitization may have been resulted into an increase in secondary porosity and thus adds to the reservoir potential ofthe Chichali Formation.
