Consists chiefly of dark dolomite in the lower part and light gray dolomite in the upper part. The base of the unit is gradational with the Chances Branch member of the Maynardville formation and contains different amounts of light gray fine-grained dolomite. Sand grains occur as scattered grains in dolomite and chert, and as thin sandstone lenses.

Dislocation creep of polycrystalline dolomite - ScienceDirect

Apr 01, 2013· Fine-grained (< 10 μm) dolomite aggregates may continue to deform by dislocation creep at temperatures up to 300 °C, but above 300 °C, diffusion creep is predicted to be the predominant deformation mechanism (Fig. 8c). One implication of this observation is that comminution of dolomite in transitional brittle–ductile faults may alter fault ...

Dolomite - an overview | ScienceDirect Topics

Dolomite is a magnesium ore with the general formula MgCO 3 ·CaCO 3. The use of dolomite as a catalyst in biomass gasification has attracted much attention (Xu, Donald, Byambajav, & Ohtsuka, 2010). The chemical composition of dolomite varies from source to source, but it generally contains 30 wt.% CaO, 21 wt.% MgO, and 45 wt.% CO 2.

Dolomite: A sedimentary rock known as dolostone or ...

The fine grain size of these crystals makes it difficult to distinguish them from calcite in thin section without the aid of staining (Fig. 9-11C). This type of dolomite replaces both the abundant pelleted muds as well as skeletal grains that characterize the backreef facies of Isla de Mona.

In contrast, the SrO contents of the dolomite minerals of fine-grained dolomite marble are basically invariable, mainly concentrating on the range of 0.1 wt%–0.2 wt%. The MnO and FeO ...

Dolomitization - an overview | ScienceDirect Topics

As shown in Table 5.12 and Fig. 5.71, a total of 10 samples of microsilt crystal-sized crystalline dolomite have an average Mg/Ca of 0.921–0.986 (already excluded are three with more than a value of one), the order degree of 0.56–0.67 (mean: 0.62) which is obviously less than 1, stoichiometric level.The very low-order degree of the dolomite represents a high speed of dolomitization.

Dolomite vs Quartzite - Compare Nature

Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors.

Ordovician period of the Ozark Plateaus in Arkansas

Geology: The Cotter Dolomite is composed of dolostone of predominantly two types: a fine-grained, argillaceous, earthy textured, relatively soft, white to buff or gray dolostone called "cotton rock", and a more massive, medium-grained, gray dolostone that weathers to a somewhat hackly surface texture and becomes dark on exposure. The formation ...
