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:

The Angouran Zn(Pb) deposit, NW Iran: evidence for a two stage, hypogene zinc sulfide-zinc carbonate mineralization
TL;DR: In this paper, the first melting points of the primary (LV) fluid inclusions in sphalerite and in hydrothermal quartz are unusually low (≤−− 60 −°C) close to the eutectic point of the ZnCl 2 -H 2 O system (−−62 −°c).

Direct evidence of fluid mixing in the formation of stratabound Pb–Zn–Ba–F mineralisation in the Alston Block, North Pennine Orefield (England)
Jon E. Bouch,Jonathan Naden,T. J. Shepherd,John A. McKervey,Brian Young,Brian Young,A.J. Benham,Hilary J. Sloane +7 more
TL;DR: In this article, a unified model that addresses the genesis of both the vein and stratabounded styles of mineralisation was presented. But the relationship between the veins and the stratabound mineralisation is not well-understood.

Stable Carbon and Oxygen Isotopic Compositions of Indian Carbonatites
TL;DR: In this article, the authors review available stable isotopic data from Indian carbonatites that span in age from Precambrian to Cretaceous and explain the observed variations using various theoretical models.
Journal ArticleDOI
Formation and destruction of periclase by fluid flow in two contact aureoles
TL;DR: Periclase formed in steeply dipping marbles from the Beinn an Dubhaich aureole, Scotland, and the Silver Star marbles, Montana, by the reaction dolomite + calcite + CO2 as mentioned in this paper.

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.
