Research Interests

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.
