TLDR
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.About:

Isotopic composition of silicon in meteorites
TL;DR: In this paper, the average Si isotope composition for each class of meteorites is identical, within analytical uncertainties, for the closed-system behavior for this element prior to meteorite accretion.
Journal ArticleDOI
Experimental determination of the ontogenetic stable isotope variability in two morphotypes of Globigerinella siphonifera (d'Orbigny)
TL;DR: It is argued that isotope fractionation is controlled by two linked processes that are affected directly by a 12C depletion or enrichment of the microenvironment via symbiont photosynthesis and host respiration, respectively.

Climatic implications of δ13C variations in a Japanese cedar (Cryptomeria japonica) during the last two millenia
Hiroyuki Kitagawa,Eiji Matsumoto +1 more
TL;DR: In this paper, a tree-ring δ 13 C of both modern Japanese cedars and of a giant Japanese cedar growing throughout the last two millennia on Yakushima Island, southern Japan, were studied.

A reevaluation of facies on Great Bahama Bank II: Variations in the d13C, d18O, and mineralogy of surface sediments
TL;DR: In this article, the authors investigated the spatial distribution of modern carbonate sediments on Great Bahama Bank, and found that most of the sediments were in C and O isotopic equilibrium with the ambient waters.

Solution behavior of reduced COH volatiles in silicate melts at high pressure and temperature
TL;DR: The solubility and solution mechanisms of reduced Csingle bondOsingle bondH volatiles in Na2Osingle-bondSiO2 melts in equilibrium with a (H2 + CH4) fluid at the hydrogen fugacity defined by the iron-wustite + H2O buffer [fH2(IW)] have been determined as a function of pressure (1−25 GPa) and silicate melt polymerization (NBO/Si: nonbridging oxygen per silicon) at 1400 °C.

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.

Variation of O18 content of waters from natural sources
S Epstein,Toshiko K. Mayeda +1 more
TL;DR: A number of marine water and fresh water samples were examined for the relative O18O16 ratio, and the variation of this ratio was determined to a precision of ± 1% as mentioned in this paper.
Journal ArticleDOI
Revised carbonate-water isotopic temperature scale
TL;DR: The relationship between temperature and O(18) content relative to that for a Cretaceous belemnite of the Pee Dee formation previously reported (Epstein, Buchsbaum, Lowenstam, and Urey, 1951) has been re-determined using modified procedures for removing organic matter from shells, and is found to be 16.5 - 4.3 δ + 0.14 δ^2

The geochemistry of the stable carbon isotopes
TL;DR: A survey of the variation of the ratio C13/C12 in nature can be found in this paper, where Urey and his co-workers used two complete feed systems with magnetic switching to determine small differences in isotope ratios between samples and a standard gas.
