DOLOMITE, VERY HIGH-MAGNESIUM CALCITE, AND
Because VHMC can be “compositionally” indistinguishable from dolomite (i.e., 50 mol% MgCO 3), the positions of the principal (104) XRD reflection for VHMC and dolomite can be identical. Nevertheless, published XRD patterns of products derived from microbial experiments lack convincing evidence of cation ordering, which is a unique characteristic of carbonate minerals exhibiting R 3
(PDF) Dolomite and Dolomitization Model- A Short Review
The model is based on two postulates, (1) that the dolomitizing brine is Mg-rich but undersaturated with both calcite and dolomite, and (2) that the dolomite-for-calcite replacement happens not by
Formation of Dolomite Composition
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite. Along with Dolomite Formation, also learn about Dolomite composition and transformation in the next section.
Dolomitization mineralogy Britannica
Dolomitization, process by which limestone is altered into dolomite; when limestone comes into contact with magnesium-rich water, the mineral dolomite, calcium and magnesium carbonate, CaMg(CO 3) 2, replaces the calcite (calcium carbonate, CaCO 3) in the rock, volume for volume.Dolomitization involves recrystallization on a large scale. The dolomite mineral grains often show distinct faces
Calcite an overview ScienceDirect Topics
Aragonite, calcite and ideal dolomite become progressively less soluble, or more stable. Protodolomite may actually be less soluble than calcite. As we will see in Chapters 5 and 7 of this book, this contrast in mineral solubility, particularly during exposure at sequence boundaries, is one of the major drivers in carbonate diagenesis and porosity/permeability evolution.

Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth’s crust. Learn more about the structure, properties, and uses of dolomite in

Dolomite and dolomitization model a short review
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 replacing the precursor mineral calcite (dolomitization process).
Degree of supersaturation and precipitation of
This paper integrates the degree of carbonate saturation into a general model for the origin of dolomite in organic-rich marine sediments. Degradation of organic matter by sulfate-reducing bacteria promotes early dolomite precipitation by simultaneously increasing the carbonate alkalinity and lowering the sulfate ion concentration to near zero.
Dolomite: A sedimentary rock known as dolostone or
Dolomite has a Mohs hardness of 3.5 to 4, and limestone (composed of the mineral calcite) has a hardness of 3. Dolomite is slightly less soluble in dilute hydrochloric acid. Calcite will effervesce vigorously in contact with cold, dilute (5%) hydrochloric acid, while dolomite produces a
Dolomite Mineral Uses and Properties
Dolomite also serves as an oil and gas reservoir rock. During the conversion of calcite to dolomite, a volume reduction occurs. This can produce pore spaces in the rock that can be filled with oil or natural gas that migrate in as they are released from other rock units. This makes the dolomite a reservoir rock and a target of oil and gas drilling.

Dolomite (rock) Wikipedia
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.In old USGS publications, it was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolomites or magnesium-rich limestones.Dolomite has a stoichiometric ratio of nearly equal amounts of

Dolomite Rock Sedimentary Rocks
Dolomite or dolostone is a carbonate sedimentary rock containing more than 50% by weight of the mineral dolomite.Dolomite rock may contain calcite, but the content of calcite should not exceed 10% of the calcite-dolomite pair’s content 3.. Dolomite in Northern Norway (Trollholmsund) which was once chalk, but the original material has been replaced with dolomite.
Thermal decomposition of natural dolomite
Abstract. Thermal decomposition behaviour of dolomite sample has been studied by thermogravimetric (TG) measurements. Differential thermal analysis (DTA) curve of dolomite shows two peaks at 777⋅8°C and 834°C. The two endothermic peaks observed in dolomite are essentially due to decarbonation of dolomite and calcite, respectively.
Preparation of high purity magnesium oxide from dolomite
03-03-2009· oxide from dolomite is the calcination route. Calcite and magnesite decompose at different temperatures, a stepwise decomposition permits the selective calcination in which magnesite is completely decomposed without decomposing calcite. Magnesium oxide is then separated physically from the calcined dolomite by sieving or air separation.

This process couples dolomite dissolution with calcite precipitation and magnesium liber-ation into the solution. 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 cavity formation by
