Reporting of relative sulfur isotope-ratio data

Abstract

To eliminate possible confusion in the reporting of sulfur isotope-ratio data, the Commission on Atomic Weights and Isotopic Abundances recommends that relative 34S/32S ratios of all sulfurbearing substances be expressed on the VCDT scale, defined by assigning a δ34S value of -0.3% exactly (relative to VCDT) to the silver sulfide reference material IAEA-S-1. Reporting of sulfur isotope-ratio analyses relative to CDT should be discontinued. © 1997, Walter de Gruyter GmbH, Berlin/Boston. All rights reserved.
