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 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

Journal of Applied Chemistry, 1952
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 ...

Epigenetic Dolomitization and the Origin of Xenotopic Dolomite Texture
SEPM Journal of Sedimentary Research, 1984ABSTRACT Xenotopic texture, which is commonly observed in pre-Cenozoic rocks, is defined here as a mosaic of anhedral crystals with irregular or curved intercrystalline boundaries and, usually, undulatory extinction. Xenotopic dolomite texture is similar in appearance to neomorphic limestone textures.

Dolomitization, Dolomite Distribution, Reservoir Rocks: ABSTRACT
AAPG Bulletin, 1970Approximately 80% of the hydrocarbon reserves in carbonate rocks in North America are found in rock that is essentially pure dolomite. In many reservoirs the field limits are determined by the distribution of dolomite, because the dolomitization process is conducive to the production of a favorable reservoir rock.
