Carbon and nitrogen isotope systematics in diamond: Different sensitivities to isotopic fractionation or a decoupled origin?
Download2016-11-16
Hogberg, Katie, Stachel, Thomas, Stern, Richard A.
Using stable isotope data obtained on multiple aliquots of diamonds from worldwide sources, it has been argued that carbon and nitrogen in diamond are decoupled. Here we re-investigate the carbon–nitrogen relationship based on the most comprehensive microbeam data set to date of stable isotopes...

This report describes the methods and samples utilized (to 2014) within the Canadian Centre for Isotopic Microanalysis (CCIM), University of Alberta, for routine analysis of δ13CVPDB, δ15NAIR, and N abundances of diamonds by secondary ion mass spectrometry (Cameca IMS 1280). Analyses by...

E. Jackson, Simon E., Bussweiler, Yannick, Hardman, Matthew, Stern, Richard A., Brey, Gerhard Peter, Kjarsgaard, B.A., Pearson, Graham, Stachel, Thomas
This study provides an experimental calibration of the empirical Al-in-olivine thermometer for mantle peridotites proposed by De Hoog et al. (2010). We report Al concentrations measured by secondary ion mass spectrometry (SIMS) in olivines produced in the original high-pressure, high-temperature,...
