Oxygen isotopic fractionation in the system quartz-albite-anorthite-water
TL;DR: Oxygen isotopic fractionations have been determined between quartz and water, albite and water and anorthite and water at temperatures from 300 to 825°C, and pressures from 15 to 25 kbar as mentioned in this paper.

TL;DR: 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.

Yong-Fei Zheng,Yong-Fei Zheng +1 more
TL;DR: In this article, the modified increment method has been applied to the calculation of oxygen isotope fractionation factors for hydroxyl-bearing silicate minerals, which can be used as a test of isotopic equilibrium or disequilibrium in natural mineral assemblages over all temperature ranges.

Water/rock interactions and the origin of H2O in granitic batholiths Thirtieth William Smith lecture
TL;DR: In this paper, a wide variety of granitic batholiths of various ages have been obtained and the primary δD values of the biotites and hornblendes are remarkably constant at about −50 to −85, identical to the values in regional metamorphic rocks, marine sediments and greeenstones.

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.

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.
