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...
Monocrystalline gem-quality diamonds from Akwatia, Ghana and De Beers Pool, South Africa have trace-element concentrations ranging from ppt to ppm levels, but mostly are below the limit of quantification. CeN/EuN (1–6; N = chondrite normalized) and CeN/TiN (0.6 to 12) indicate mildly elevated...
δ13C and δ15N Signatures in Muscle and Fin Tissues: Nonlethal Sampling Methods for Stable Isotope Analysis of SalmonidDownload
Stable isotope analysis has emerged as an important tool in aquatic ecology. For fish, dorsal muscle from sacrificed individuals has traditionally been used in stable isotope studies; however, there are many instances when lethal sampling is undesirable. We evaluated the feasibility of using...
