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:

Stable isotope and geochemical evidence of formation pore fluid evolution during diagenesis of Tertiary sandstones and mudrocks of the Niger Delta
TL;DR: Petrological data provided evidence that framboidal pyrite, Fe-carbonates and kaolinite are the major diagenetic minerals developed during burial diagenesis in the Tertiary Niger Delta sandstones and associated mudrocks as mentioned in this paper.

Oxygen and carbon isotope compositions of carbonates in a prominent lithologically mixed unit in the central South Norwegian Caledonides
TL;DR: In this article, the carbonate stable isotope data of a pre-Scandian lithologically mixed unit in the central South Norwegian Caledonides is presented. But the carbonates of the mixed unit between Bergen and Otta (re-)equilibrated at unit-wide similar peak metamorphic conditions.

Datation et caractérisation de processus minéralisateurs à l'Archéen : Application à l'Antimony Line, Ceinture de Roches Vertes de Murchison, Afrique du Sud
TL;DR: Les circulations de fluides dans la croute sont les vecteurs de mobilites elementaires, dont une des consequences est la concentration de metaux and la genese de gisements.

Fluid transfer in anorthosites and related rocks from Rogaland (Southwest Norway): Evidence from stable isotopes
TL;DR: In this article, the authors measured sixteen samples of the anorthosite massif-type Anorthosite (Rogaland, Southwest Norway) and in 30 surrounding rocks, including the metamorphic envelope and magmatic intrusions related to the emplacement.

Early Dinantian dolomites from East Fife: hydrothermal overprinting of early diagenetic fabrics?
TL;DR: In the early Dinantian succession of East Fife, the dolomite is fine-grained and homogeneous in backcattered SEM images as discussed by the authors, and it generally contains 7-11 mol% FeCO 3, and 49-52 mol% CaCO 3.

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.
