Dolomite

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

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 …

Origin of Dolomite in Lacustrine Organic-Rich Shale: A Case …

In most organic-rich shale reservoirs, dolomite is widely distributed and has different types and crystal sizes.

The standard unit cell parameters of …

Frontiers | Dolomite Origins of the Carbonate Successions …

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 …

Low-Temperature Synthesis of Disordered Dolomite and …

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
