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...

Formation of mixed paragenesis diamonds during multistage growth – constraints from in situ δ 13C–δ 15N–[N] analyses of Koidu diamonds

Lai, Mei Yan, Stachel, Thomas, Stern, Richard A., Hardman, Matthew F., Pearson, D. Graham, Harris, Jeff W.
Abstract Inclusion-bearing diamonds from the Koidu kimberlite complex, Sierra Leone (West African Craton) were analyzed in situ for carbon and nitrogen isotope compositions, nitrogen concentrations and nitrogen aggregation states. In a suite of 105 diamonds, 78% contain eclogitic mineral...

δ13C and δ15N Signatures in Muscle and Fin Tissues: Nonlethal Sampling Methods for Stable Isotope Analysis of Salmonid
Download2010
Paszkowski, C.A., Hanisch, J.R., Tonn, W.M., Scrimgeour, G.J.
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...
