Geosphere, June 2015, v. 11, p. 786-822, doi:10.1130/GES01092.1, Supplemental File 2 - SHRIMP U-Pb zircon data from the Fortymile district, east-central Alaska. Part A describes the analytical methods used for U-Pb geochronology of zircon. Part B presents representative cathodoluminescence images of zircon, concordia plots, and weighted average plots. Part C presents information used in the interpretation for analytical results for each dated sample, including the morphology and cathodoluminescence zoning characteristics of its zircon.
