A difference of 0.61‰ is reported between dolomite (− 1.66‰) and its precursor, limestone (− 1.05‰), in the Yeoman Formation (Red River equivalent) of the Williston Basin, southeastern Saskatchewan.The significance of the large difference found, and the preference for light isotope enrichment in the dolomite, is evaluated with assistance from 87 Sr/ 86 Sr ratios …
Dolomite lime is a type of lime containing both calcium carbonate and magnesium carbonate. It comes from underground limestone deposits, which appear as white, tan, gray, or pink crystals. Dolomite lime is used to raise soil pH, and it adds both calcium and magnesium to soil.
The Lower Cambrian Changping Formation in the Western Hills of Beijing hosts tidal flat and lagoonal carbonates comprising dolomites, limestones, and dolomitic limestones, reflecting the processes of dolomite cementation and dolomitization within a sedimentary framework. Based on petrographic textures, two types of dolomites were identified: …

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO 3) 2. It is the primary component of the sedimentary rock known as …
Like dolomite, limestone loading also had an inverse relation with CO yield at lower temperatures. The maximum CO yield of 20.46 vol% was obtained at optimized temperature of 900 °C without using a catalyst. The cement catalyst produced the highest CO yield of 22.05 vol% following by the limestone (19.97 vol%) and dolomite (17.65 vol%). 3.4.
Dolomite is a type of limestone that contains magnesium crystals. The Dolomite is slightly more complex than limestone. Limestone has a hardness of 3, while Dolomite has a hardness of 3.5 to 4.
Since the dolomite and limestone used in this research were obtained by crushing and sieving, the corresponding value of Waddell's sphericity factor, ψ, is 0.8–0.9 (Geldart, 1986), with an average value of 0.85. Fig. 5 shows that the volume diameters of the dolomite and limestone particles are 171 μm and 154 μm, respectively. The surface ...

While dolomite and limestone share similar physical properties due to their calcium carbonate content, the presence of magnesium in dolomite imparts some distinguishing characteristics. Dolomite is typically harder than limestone, ranking around 3.5 to 4 on the Mohs hardness scale, while limestone generally falls between 3 and 4.
The name limestone is from limus (Latin) for mud. The name marble is derived from the Latin marmor and from Greek, which means a shining stone. Strictly the name applies to a granular, crystalline limestone, but it is also applied to a hard limestone that can be polished. Dolomite was named in 1794 after D. de Dolomieu, a French mineralogist ...

However, replacive or secondary origins are considered unlikely for the limestone-hosted dolomite in Shibantan because 1) the Shibantan Member formed in a relatively deep-water limestone environment (Xiao et al., 2020a), which is inconsistent with an evaporitic model involving replacement of aragonite or calcite by dolomite, which is not ...
Assessment of the wellbore stability and the sustainability of the wormhole structure depends on the mechanical rock properties after acidizing. In this study, three rock lithologies (chalk, limestone, and dolomite) were treated with acid at different injection rates to establish acid efficiency curves.

The use of dolomite also resulted in the highest levelised cost of hydrogen (5.4 €/kg against 5.0 €/kg when limestone is used as sorbent), which translates into a CO 2 avoided cost ranging between 114.9 €/tCO 2 (natural limestone) and 130.4 €/tCO 2 (dolomite). Although doped limestone has shown a CO 2 avoided cost of 117.7 €/tCO 2 ...
