Estimation of Dolomite Formation: Dolomite Precipitation and Dolomitization

open access: yesJournal 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 ...

Origin and evolution of fault-controlled hydrothermal dolomitization fronts: A new insight [PDF]

open access: yesEarth and Planetary Science Letters, 2020
Dolomitization is one of the most significant diagenetic reactions in carbonate systems, occurring where limestone (CaCO3) is replaced by dolomite (CaMg (CO3)2) under a wide range of crystallization temperatures and fluids.

Autochthonous Micrite to Aphanodolomite: The Microbialites in the Dolomitization Processes

open access: yesGeosciences (Switzerland), 2018
In the present paper, we examine the influence of micrite types, autochthonous or allochthonous, on the dolomitization processes. The recrystallized and dolomitized Carnian samples from Rifugio Vallandro and Alpe di Specie erratic boulders (South Tyrol ...

Dolomitization and the causes of dolomitization dolomite reservoir

Chinese Journal of Geochemistry, 2012
This 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

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.

Epigenetic dolomitization and the origin of xenotopic dolomite texture

Journal of Sedimentary Research, 1984
Abstract 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.
