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...
