Accurate Determination of Zr Isotopic Ratio in Zircons by …
isotope zoning has been observed in single zircon grains. The micro-analyses of Zr isotopes are the powerful tools to identify the characteristics of these Zr isotope zoning (Kirkpatrick et al., 2019; Zhang et al., 2019). Kirkpatrick et al. (2019) reported the first in-situ analysis of δ94/90Zr in zircon using SIMS. The

Method of micro‐sampling human dentine collagen for stable isotope …
Rationale. Sampling of dentine for stable carbon (δ 13 C) and nitrogen (δ 15 N) isotope ratios in the direction of tooth growth allows the study of temporal changes to the diet and physiological stress of an individual during tooth formation. Current methods of sampling permanent teeth using 1 mm increments provide temporal resolution of 6–9 months at best …
