A significant fraction of our work involves understanding radiation damage in zircon, and much of this work is done with Raman Spectroscopy. 1) Research results and PDFs from the Union College FT lab (see list below) 2) Fission-track theses completed at Union College. Using this approach we are able to routinely analyze single zircon grains to gain a better understanding of geochronometric analyses.

The focus here is on detrital zircon that has been dated by fission-track and by uranium-lead methods, and therefore we know actinide concentrations in individual crystals. Shift in the Raman wavenumber of the ν3(Si O4) peak is directly related to actinide content and degree of radiation damage.
