GGR Biennial Critical Review: Analytical Developments Since 2014

摘要: This GGR biennial critical review covers developments and innovations in key analytical methods published since January 2014, relevant to the chemical, isotopic crystallographic characterisation of geological and environmental materials. In nine selected fields, publications considered be wide significance are summarised, background information is provided their importance evaluated. addition instrumental technologies, this also presents a summary new preparation of rock, microanalytical reference materials, including precis recent changes revisions ISO guidelines for material reporting. Selected reports are isotope ratio determinations by both solution nebulisation MC-ICP-MS laser ablation-ICP-MS, as well radioactive isotope geochronology LA-ICP-MS. Most techniques elaborated continue provide applications for geochemical analysis; however, it noted that instrumental neutron activation analysis has become less popular in recent years, mostly due reduced availability nuclear reactors act source. Many newer applications reported here at increasingly finer resolution. Examples include atom probe tomography, very sensitive method providing atomic scale information, nanoscale SIMS, imaging of geological biological samples,
