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...

Diamond sources beneath the Hall Peninsula, Baffin Island, Nunavut: A preliminary assessment based on Chidliak diamonds
DownloadSpring 2014
Diamonds from the Chidliak kimberlite field, located on the Hall Peninsula of Baffin Island, are the focus of this study. Morphology, carbon and nitrogen isotopic compositions, and nitrogen characteristics of Chidliak diamonds are used to constrain diamond sources, and conditions of diamond...

Recommendations for offline combustion-based nitrogen isotopic analysis of silicate minerals and rocks
Download2021-03-01
Li, Long, Li, Kan, Li, Yingzhou, Du, Yifan, Labbe, Mark
Rationale Due to isotope fractionations during partial nitrogen release from minerals and rocks, the complete extraction of nitrogen for analysis is crucial to ensure high-quality nitrogen isotopic data. However, the appropriate nitrogen extraction conditions (e.g. temperature, duration) have not...
