TL;DR: In this paper, a multidisciplinary investigation of gold in four Siberian mesothermal gold deposits was done through a multiscale investigation (including ore microscopy, INAA, SIMS, EPMA, and 197 Au Moessbauer spectroscopy).
Journal ArticleDOI
Chemical speciation of gold in arsenopyrite
Louis J. Cabri,Matthew Newville,Robert A. Gordon,E. Daryl Crozier,Stephen R. Sutton,G. McMahon,De-Tong Jiang +6 more
TL;DR: In this paper, the speciation of Au in gold-bearing arsenopyrite (FeAsS) from four gold deposits (Olympiada, Sentachan, Sao Bento and Sheba) was determined by micro-X-ray absorption near-edge structure (XANES) on grains well characterized microscopically and by electron-microprobe and secondary-ion mass spectrometry analyses and images.
Journal Article
Pt, Pd and other trace elements in sulfides of the Main Sulfide Zone, Great Dyke, Zimbabwe; a reconnaissance study
Journal ArticleDOI
Quantitative imaging of cells with multi-isotope imaging mass spectrometry (MIMS)—Nanoautography with stable isotope tracers
TL;DR: In this paper, the authors describe some technical aspects of the application of multi-isotope imaging mass spectrometry (MIMS) to biological research, particularly the use of isotopic tags to localize and measure their incorporation into intracellular compartments.
