Furthermore, the stable isotope systems of many of the transition metals have emerged as tracers of many of these processes. A new multi-step chemical separation procedure, validated using multiple rock and other standards, was applied to the study of black shales and carbonates spanning the end-Ordovician, a period of large-scale global change. This method allows us to quantitatively, and with negligible blank contribution, isolate and measure the isotope systems of the transition metals Fe, Ni, Cu, Zn, and Mo at high precision, from a single sample aliquot and from a range of sample matrix types.
