Minerals (Basel, Switzerland), 2021 Dolomite plays an important role in carbonate reservoirs. The topography in the study area creates conditions for reflux dolomitization. The northeastward paleogeomorphy during the deposition of the Yingshan Formation was favorable for reflux ...

Dolomitization and the causes of dolomitization dolomite reservoir
Chinese Journal of Geochemistry, 2012This paper utilizes multi-methods, such as core observation, slice identification, isotope analysis, trace element analysis, fluid inclusion technique and so on, to study the causes of the dolomite in the Nanpu Sag and the origins of the dolomite reservoir.

Chapter 7 Dolomites and Dolomitization
1979Publisher Summary This chapter discusses dolomites and dolomitization. There are numerous kinds of dolomite. According to numerous investigators, primary precipitation of dolomite crystals, particularly in marine environments, probably represented in Holocene carbonate sediments, is of little significance when considering the great bulk of ancient ...

II.—Dolomitization and the Leicestershire Dolomites
Geological Magazine, 1918In the district north of Ashby-de-la-Zoueh dolomitized Carboniferous Limestone crops out where the Leicestershire border adjoins that of South Derbyshire. The dolomites, which attain a thickness of nearly 900 feet in this area, have hitherto received very little attention.

Fluidization characteristics of dolomite and calcined dolomite particles
Chemical Engineering Science, 2000Abstract Experimental measurements were performed of the minimum fluidization velocities and the terminal velocities of a bed of dolomite and its calcine. Using air, experiments were conducted in an 8.5 cm i.d. column with very narrow fractions of particles in a range of 0.14– 0.72 mm .

Dolomite-dolomite separation by a selective flocculation technique
Mining, Metallurgy & Exploration, 1995The viability of physico-chemical purification methods such as selective flocculation for the separation of two components having similar chemical compositions and the same crystal structure but different surface properties is demonstrated. A loss of selectivity was observed in a dolomite-dolomite mixture when polyethylene oxide (PEO) (five million ...

The thermochemical activity of dolomite occurred in dolomite–palygorskite
Applied Clay Science, 2016Abstract Dolomite–palygorskite (DP) composed of dolomite and palygorskite is a kind of special palygorskite. In this work, the phase, microstructure, and morphology of DP were characterized before and after calcination using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and transmission electron microscopy (TEM ...

Carbonates and Evaporites, 2005
The wavelengths of nanometer-scale structural modulations in calcium-rich dolomite on the Latemar buildup, Dolomites, northern Italy vary as a function of composition, which is controlled by the temperature of dolomitizing fluids, and contact time with these fluids. Dolomites formed at the highest temperatures are the most magnesian and those formed at

AbstractThe thermal decomposition of dolomite at various constant temperatures and carbon dioxide pressures has been investigated by the ‘loss‐of‐weight method.’ Depending on these conditions, dolomite can be decomposed either stepwise to magnesium oxide and calcium carbonate (‘half‐burnt dolomite’) with subsequent dissociation of calcium carbonate, or

Dolomitization of the Latemar platform: Fluid flow and dolomite evolution
Marine and Petroleum Geology, 2014Abstract The Anisian–Ladinian Latemar platform, northern Italy, presents a spectacularly exposed outcrop analogue for dolomitized carbonate reservoirs in relation to fracture-controlled igneous intrusions. Although the Latemar is one of the best studied carbonate platforms worldwide, timing and evolution of dolomitization and the link to fractures ...
