Dolomite and dolomitization model - a short review

2018-7-13 · On the basis of the mode of formation, dolomites can broadly be divided into two groups: primary dolomite and secondary dolomite.2 Primary dolomite precipitate directly from aqueous solution, mostly at or near room temperature (20-35oC), with no CaCO 3 dissolution involved.3 However, dolomite can also form as a secondary phase

Evamy [1967] described dedolomit-ization as a one-step process in which dolomite is replaced by the formation of calcite. In contrast, Kenny [1992] considers dedolomitization as a two-step process, involving

CEBU’S DOLOMITE - Mines & Geosciences Bureau - Region 7

The dolomite in Cebu is a sedimentary carbonate rock that has a high content of the mineral dolomite, CaMg(CO3)2. This mineral is generally used as an auxiliary material for iron and steel; sintering agent and flux in metal processing; ingredient in the production of glass, bricks and ceramics; utilized as fertilizer and soil conditioner; and feed additives for livestock, among others.

Dolomitization - an overview | ScienceDirect Topics

Dolomites are carbonate rocks mainly composed of the mineral dolomite. The mineral is stable in seawater in nature and not known examples of its direct extraction from seawater in large quantities required for origin of dolomite rocks. Dolomite occurs by suppression of aragonite or calcite, i.e. dolomitization process.
