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:

Semi-automatic determination of the carbon and oxygen stable isotope compositions of calcite and dolomite in natural mixtures
M. Baudrand,Giovanni Aloisi,Christophe Lécuyer,François Martineau,François Fourel,Gilles Escarguel,M. M. Blanc-Valleron,Jean-Marie Rouchy,Vincent Grossi +8 more
TL;DR: In this paper, a semi-automatic on-line method was developed to determine the delta(13)C and delta(18)O values of coexisting calcite and dolomite.

Early dolomitization and recrystallization of the Lower-Middle Ordovician carbonates in western Tarim Basin (NW China)
TL;DR: Based on petrographic textures, three types of matrix dolomites were identified: (1) very finely to finely crystalline, nonplanar-a to planar-s dolomorphite (Md1), (2) medium crystalline and planar e(s) dolmorphite (md2) as mentioned in this paper.

Oxygen and carbon isotopic study on the genesis of the Steirischer Erzberg siderite deposit (Austria)
TL;DR: In this article, the carbon and oxygen isotopic composition of Fe-carbonate ore and its calcitic to dolomitic Devonian host rocks at the Steirischer Erzberg siderite deposit (Greywacke zone, Upper Austroalpine Unit) were determined in order to constrain the source and nature of the Fe-rich mineralizing fluid.

The Zn-Pb Mineralization of Florida Canyon, an Evaporite-Related Mississippi Valley-Type Deposit in the Bongará District, Northern Peru
Saulo Batista de Oliveira,David L. Leach,Caetano Juliani,Lena Virgínia Soares Monteiro,Craig A. Johnson +4 more
TL;DR: The Florida Canyon sulfide-related Zn-Pb sulfide deposit in northern Peru is one of the largest Mississippi Valley-type deposits in South America as mentioned in this paper, and a dome structure that controls the location of the ore deposit was defined by drill hole spatial data; the dome likely resulted from halokinetic processes during Andean deformation.

Diagenesis and fluid system evolution in the northern Oman Mountains, United Arab Emirates: Implications for petroleum exploration.
TL;DR: In this paper, the diagenesis and fluid system evolution of outcrop analogues of potential sub-thrust Cretaceous carbonate reservoirs in the Musandam Peninsula, northern United Arab Emirates, is reconstructed during the successive stages of the Oman Mountains development.

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.
