FIGURE 2. Examples of zircon subpopulations recovered from TBM tuff sample PCM3 Aug14-04, shown in their approximate abundances. Longitudinal bubble tracks and elongate habits (upper right) are typical of ash-fall zircons. CA-TIMS dating was limited to single zircons from the ash-type and euhedral subpopulations. The rounded grains are likely to be older, detrital grains incorporated into the tuff during deposition. Scale bars in micrometers (μm).
