Equilibrium and kinetics in dolomite precipitationSeawater is the only abundant source of Mg 2+ capable of forming large and widespread volumes of sedimentary dolomite, at or near the earth's surface Land, 1980, Land, 1985.It contains 1290 ppm Mg (0.052 mol l −1), and 411 ppm Ca (0.01 mol l −1) giving a Mg/Ca ratio of 3.14 by weight or …
This is probably dolomite countertops' greatest strength over quartz. The engineered stone is offered in beautiful white and gray hues as well, and it is more resistant to scratches and stains than dolomite. But quartz can't take heat or sunlight, a hot pan will mark it for life. Dolomite can, and it will hold heat really well.
Dolomite stoichiometry in MV1 and MV2 were determined from single point analyses where Ca, Mg, Mn, and Fe of dolomite were quantified and compared to standard dolomite (Table 2).

The "Dolomite Problem" has been a controversy for over a century, owing to massive assemblages of low-temperature dolomite in ancient rocks with little dolomite forming today despite favorable ...
Dolomite as a ceramic material is a uniform calcium magnesium carbonate. In ceramic glazes, it is used as a source of magnesia and calcia. Other than talc, dolomite is the principal source of MgO in high-temperature raw glazes. 'Dolomite matte' stoneware glazes, for example, are highly prized for their pleasant 'silky' surface texture.

Dolomite is an anhydrous carbonate mineral made up primarily of calcium magnesium carbonate (CaMg (CO3)2). A sedimentary carbonate rock consisting primarily of the mineral dolomite is also known as a dolostone rock or dolostone rock type. The word "dolostone" is often used to refer to the dolomitic rock type. Dolomite is a type of …
In most organic-rich shale reservoirs, dolomite is widely distributed and has different types and crystal sizes. However, the characteristics and formation mechanism of the dolomites in organic-rich shale are still poorly understood. Petrographic and geochemical analyses were performed to interpret the formation of dolomite in the lacustrine organic …
In an ideal structure of dolomite, alternating layers of Mg 2+, Ca 2+ are interspersed with CO 3 2− groups oriented normal to the c-axis (Fig. 1), with a Mg/Ca molar ratio of 1 (stoichiometry) and an ordered arrangement.The larger radius Ca 2+ occupy A sites and the smaller radius Mg 2+ occupy B sites. The standard unit cell parameters of …
1 Introduction. The dolomite origins and dolomitizing processes have been extensively studied by petroleum geologists because the dolostones provide approximately 50% of the carbonate hydrocarbon reservoirs (Zenger et al., 1980; Sun, 1995; Ma et al., 2007).This percentage increases to more than 80% at deep-burial formations (i.e., depths …
How dolomite [CaMg(CO3)2] forms is still underdetermined, despite over a century of efforts. Challenges to synthesizing dolomite at low temperatures have hindered our understanding of sedimentary dolomite formation. Unlike calcium, magnesium's high affinity toward water results in kinetic barriers from hydration shells that prevent …
Sedimentary rock - Limestones, Dolomites, Calcite: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of …

When you are cleaning your dolomite, avoid using acidic cleaners which include lemon juice or vinegar, ammonia, or other harsh chemicals. We recommend …
In recent years, with the fine exploration of carbonate reservoirs in the Qixia Formation, central Sichuan Basin, researchers have made important oil and gas discoveries in the dolomite reservoirs. However, the characteristics, genesis and controlling factors of dolomite reservoirs in the Qixia Formation in this area are still unclear. In this paper, the …

A favorite destination of nature lovers, the Dolomites, or Dolomiti in Italian, is a mountainous region that is part of the Northern Italian Alps. Dominated by 18 majestic peaks, its diverse landscape consists of more than 350,000 acres of jagged pinnacles, sheer rock faces, icy glaciers, deep gorges, lush forests, and verdant valleys.
