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:

Fluid inclusion and stable isotope (O, H, C, and S) constraints on the genesis of the Serrinha gold deposit, Gurupi Belt, northern Brazil
Evandro Luiz Klein,Chris Harris,Chris Harris,Christophe Renac,André Giret,Candido Augusto Veloso Moura,Kazuo Fuzikawa +6 more
TL;DR: The Serrinha gold deposit of the Gurupi Belt, northern Brazil, belongs to the class of orogenic gold deposits as mentioned in this paper, and is hosted in highly strained graphitic schist belonging to a Paleoproterozoic metavolcano-sedimentary sequence.

Dolomitization of Lower Cretaceous Peritidal Carbonates By Modified Seawater: Constraints From Clumped Isotopic Paleothermometry, Elemental Chemistry, and Strontium Isotopes
TL;DR: In this paper, the authors investigated one of the few examples of dolomitization of Lower Cretaceous shallow-water limestones from the southern Tethys carbonate platform from outcrops on the Haushi-Huqf High in central-east Oman.

The Anatomy of an Early Dinantian Terraced Floodplain: Palaeo‐Environment and Early Diagenesis
TL;DR: In this paper, the lowermost Carboniferous rocks in the Cockburnspath area of east Berwickshire (southern Scotland) are interpreted as coastal floodplain sediments.

Early and late Neoproterozoic C, O and Sr isotope chemostratigraphy in the carbonates of West Congo and Mbuji-Mayi supergroups: A preserved marine signature?
Franck Delpomdor,Alain Préat +1 more
TL;DR: In this article, the fidelity of δ13Ccarb and Sr signatures in Neoproterozoic carbonates was discussed on the basis of a severe diagenetic control, using trace and major geochemistry, combined with C and O stable isotope analysis, highlighting that the δ 13Ccarb fluctuations of the Schisto-Calcaire Subgroup reflect (i) facies variations, (ii) exchanges between isotopically light carbon in meteoric waters and carbonate during lithification and early diagenesis, and/or (iii) regional metamorph

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.

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.
