Carbon and nitrogen isotope systematics in diamond: Different sensitivities to isotopic fractionation or a decoupled origin?Download
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 diamondsDownload
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...
The Chidliak kimberlite pipe is located on the Hall Peninsula on Baffin Island in Nunavut. The first kimberlite in Chidliak was discovered in 2008. Previous studies (e.g., Hogberg et al., 2016) on Chidliak inclusion-free diamonds have suggested that 1) two diamond growth stages are recorded by...
