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:

Oxygen-isotope studies of clastic diagenesis in the Lower Cretaceous Viking Formation, Alberta: implications for the role of meteoric water
Fred J. Longstaffe,Avner Ayalon +1 more
TL;DR: In this article, the paragenetic sequence of diagenetic minerals from the Lower Cretaceous Viking sandstone and conglomerate from south-central Alberta, Canada have been used to identify changes in porewater composition during diagenesis and to relate these changes to major geological events within the western Canada sedimentary basin.

Mass-independent fractionation of oxygen isotopes during thermal decomposition of carbonates
Martin F. Miller,Ian A. Franchi,Mark H. Thiemens,Teresa L. Jackson,André Brack,Gero Kurat,Colin T. Pillinger +6 more
TL;DR: Findings of a 17O anomaly being generated from a solid, and solely by thermal means, provide a further challenge to current understanding of the nature of mass-independent isotopic fractionation.

Reflux stratabound dolostone and hydrothermal volcanism‐associated dolostone: a two‐stage dolomitization model (Jurassic, Lebanon)
TL;DR: The Kesrouane Formation as mentioned in this paper is a broad carbonate platform deposited in the Levant region and represents 60% of the Lebanese Jurassic rocks, and two genetically distinct dolostones are recognized within this unit: (1) fine-to-medium crystalline non-planar grey Dolostone; and (2) coarse-crystalline planar beige DOLostone.

Stable isotope geochemistry of the Archean Val-d‘Or (Canada) orogenic gold vein field
Georges Beaudoin,David Pitre +1 more
TL;DR: A systematic study of the auriferous quartz veins of the Val-d'Or vein field, Abitibi, Quebec, Canada, demonstrates that the C, O, S isotope composition of silicate, carbonate, borate, oxide, tungstate and sulphide minerals have a range in composition comparable to that previously determined for the whole Superior Province.

Blas L. Valero-Garcés,Antonio Delgado-Huertas,Ana Navas,J. Machín,Penélope González-Sampériz,Kerry Kelts +5 more
TL;DR: In this paper, the Limnological Research Center contribution number 527 was used to support the work of the National Science Foundation, USA under the EAR 941-8657 programme, and by the EEAD-CSIC project number Z-5-96.

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.
