TLDR
In this paper, an empirically derived relationship between the chemical composition of a carbonate in the CaCO3-(Ca, Mg)(CO3)2-FeCO3 system and the function 103 In α at 100°C is 103 ∆ α = 8.94XCaCO3 + 9.29XMgCO3+ 8.77XFeCo3 where Xi is the mole percent of component i in the carbonate.About:

Stochastic Joint Simulation of Facies and Diagenesis: A Case Study on Early Diagenesis of the Madison Formation (Wyoming, USA)
Mickael Barbier,Mickael Barbier,Youri Hamon,Brigitte Doligez,Jean-Paul Callot,Marc Floquet,Jean-Marc Daniel +6 more
TL;DR: In this article, an integrated approach to reproduce both facies and diagenetic trends in a static reservoir model based on an outcrop case study is proposed, which corresponds to a carbonate ramp progressively evolving towards the most inner part of a platform.
Origin of authigenic carbonates in Eocene to Quaternary sediments from the Arctic Ocean and Norwegian-Greenland Sea
TL;DR: Authigenic carbonates occur in thin layers, nodules, and burrows in fine-grained siliciclastic sediments of middle Eocene to Quatemary age that were recovered from the Arctic Ocean and Norwegian-Greenland Sea during Leg 151 as mentioned in this paper.

Constraints of fluid inclusions and C, O isotopic compositions on the origin of the dolomites in the Xisha Islands, South China Sea
TL;DR: In this paper, the origin and evolution of dolomite-hosted fluid inclusions were traced in detail, which provided important evidence for establishing the DOLOMITization model of the primary Dolomites in the Xisha Islands.
Journal ArticleDOI
Origin of the Rubian carbonate-hosted magnesite deposit, Galicia, NW Spain: mineralogical, REE, fluid inclusion and isotope evidence
TL;DR: The Rubian Magnesite mine as discussed by the authors is a 100m-thick folded and metamorphosed Lower Cambrian carbonate/siliciciclastic metasedimentary sequence.

Unique siderite occurrence in Baltic Sea: a clue to siderite-water oxygen isotope fractionation at low temperatures
Stanisław Hałas,Roman Chlebowski +1 more
TL;DR: Recently formed siderite (between 1785 and 1996) at the bottom of South Baltic Sea was investigated by thin section petrography, XRD, electron microprobe (determination of major cation content) and mass spectrometry (d13 C and d18 O analysis).

Isotopic standards for carbon and oxygen and correction factors for mass-spectrometric analysis of carbon dioxide
TL;DR: In this paper, Niee's and Solenhofen standards were compared to the Chicago PDB standard for carbon and oxygen isotope ratios, and the correction factors for instrumental effects and for the nature of the mass spectra were derived.

On the Isotopic Chemistry of Carbonates and a Paleotemperature Scale
TL;DR: In this paper, the temperature variation of the fractionation of oxygen in exchange reactions between dissolved carbonate and water and between calcite and water was calculated on theoretical grounds, and checked experimentally.

The use of bromine pentafluoride in the extraction of oxygen from oxides and silicates for isotopic analysis
TL;DR: In this paper, a technique was developed in which bromine pentafluoride was used as a reagent for quantitative liberation of oxygen from oxides and silicates, and the results of isotopic analyses were compared with measurements made in other laboratories by other procedures.
Journal ArticleDOI
Measurement of O18O16 ratios of total oxygen of carbonates
TL;DR: The commonly used phosphoric acid procedure for the determination of oxygen isotope abundances in carbonates involves a large kinetic isotope effect as mentioned in this paper, which leads to an overestimate of the dolomite-calcite oxygon isotope fractionation by 0.8 per mil.
