Estimation of Dolomite Formation: Dolomite Precipitation and Dolomitization

Journal of the Geological Society of India, 2016
Abstract: Reactive-transport models are developed here that produce dolomite via two scenarios: primary dolomite (no CaCO3 dissolution involved) versus secondary dolomite (dolomitization, involving CaCO3 dissolution). Using the available dolomite precipitation rate kinetics, calculations suggest that tens of meters of thick dolomite ...

The thermochemical activity of dolomite occurred in dolomite–palygorskite

Applied Clay Science, 2016
Abstract 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 ...

Chapter 7 Dolomites and Dolomitization

1979
Publisher 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, 1918
In 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, 2000
Abstract 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 .
