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:

Origin of dawsonite-forming fluids in the Mihályi-Répcelak field (Pannonian Basin) using stable H, C and O isotope compositions: Implication for mineral storage of carbon-dioxide
Dóra Cseresznyés,György Czuppon,Csilla Király,Attila Demény,Domokos Györe,Viktória Forray,Ivett Kovács,Csaba Szabó,György Falus +8 more
TL;DR: In this article, the Mihalyi-Repcelak field (Pannonian Basin, Central Europe) is one of the largest natural CO2-bearing reservoirs in Europe (25 Mt).

Diagenetic minerals from saline diapirs as thermodynamic, chemical and isotopic tracers of evolution in the North Tunisian sedimentary basin and their impacts on ore deposits genesis
TL;DR: In this article, the impacts of diapir evolutions on the ore deposits genesis were investigated using combined mineralogical, Raman spectrometry and C-, O- and H- isotopes studies of fluid inclusions trapped by their minerals.
Journal ArticleDOI
Traces of brine and hydrocarbon migration in carbon, oxygen, and sulfur isotopic compositions of reservoir rocks in the Talakan petroleum field, Southwestern Yakutia
TL;DR: In this paper, the Osa horizon has a carbon isotopic composition within the range of normal marine carbonates (δ13C = 0 ± 1 ‰), which does not indicate a significant role of organic matter in postsedimentary recrystallization of carbonate sediments.
Journal ArticleDOI
Stable isotope geochemistry of organic matter alteration in Animikie Basin sediments within the thermal aureole of the Duluth Ccomplex
TL;DR: In this article, total organic carbon, total carbonate carbon (TCC), and δ 13 C values for TOC in samples from the Early Proterozoic Animikie Basin sediments (Virginia and Biwabik Iron Formations) that have been variably metamorphosed by the Duluth Complex were determined.
Origin of carbonate concretions from mud mounds in the Gulf of Cadiz (SW Iberian Peninsula)
Marta Rejas,Concepción Taberner Hernández,Juan José Pueyo,Santiago Giralt,María Pilar Mata Campo,Jordi M. de Gibert,Víctor Díaz del Río Español +6 more
TL;DR: A study of carbonate concretions from the Iberico, Cornide and Arcos mud mounds in the Diasom Field was undertaken to better understand the origin and type of fluids from which these carbonretions precipitated.

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.
Journal ArticleDOI
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.
