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:

Pedogenic, palustrine and groundwater dolomite formation in non-marine bentonites (Bavaria, Germany)
Mathias H. Köster,H. A. Gilg +1 more
TL;DR: In this paper, the role of authigenic carbonate formation during bentonitization was investigated using petrography, field-emission scanning electron microscopy and stable isotope geochemistry.

Reconstructing paleoceanographic conditions during the middle Ediacaran: Evidence from giant ooids in South China
TL;DR: In this paper, a newly-discovered deposit of giant ooids in the Nanshanping outcrop in South China contains a relatively intact record of the rare earth elements and yttrium (REY) composition of Ediacaran seawater, providing an important window into the redox state of the surface ocean at this time.

Lacustrine Sedimentology, Stratigraphy and Stable Isotope Geochemistry of the Tipton Member of the Green River Formation
TL;DR: The Tipton Member of the Green River Formation (GGRB) is known to record a single shift from open to partly closed hydrology, which is each recorded by distinct transitions in facies associations, geochemistry, carbonate mineralogy, and organic content as discussed by the authors.

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.
