Dr. Desmond Moser
conducts solid Earth and planetary science research using Western’s nationally
unique Zircon and Accessory Phase Laboratory (ZAPLab). Micromineral crystal
growth and deformation analysis (e.g. CL, EBSD) is integrated with field
mapping, microchemical (EDS, WDS), petrologic and mass spectrometry
measurements (radiogenic and stable isotopes) at Western and partner institutes.
His active projects investigate meteorites, crustal cross-sections, kimberlite
xenoliths, sedimentary basins and impact structures in the Americas, Africa and
Europe. His ZAPLab team is advancing our knowledge of the timing and nature of
processes that form and modify planetary crusts and ore deposits while
advancing the growing sub-discipline of accessory mineral science.
