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.

The outflow of lagoonal waters along the seafloor to the open sea of the transition zone may explain both: partial dolomitization of host rocks of Pirgu age and the occurrence of chlorite-smectite in host rocks (Kiipli et al.
It contains ellipsoidal primordial facies, complete dolomitization and vuggy porosity of touching-vug type.
In all zones of karst and dolomitization, the content and quality of shale kerogen is diminished [21].
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).

Bioturbation influences dolomitization patterns in carbonate rocks
Post-mound early diagenesis including calcite cementation and dolomitization was controlled by a second period of subaerial exposure after the mound had become buried beneath peritidal mudstone.
It is possible that the silica was derived from the host rock during early diagenesis late in the Permian Period, however, this is difficult to ascertain because of the extensive dolomitization of the rock body.
