Methodology
  • We report 29 new detrital zircon U-Pb age samples (Table S1) from Cenozoic sandstones and modern river sands comprising 7,094 total ages (Table S2). Mineral separation was conducted at the University of Michigan. Heavy mineral fractions were mounted in epoxy and polished to expose crystal interiors. Mounts were made of entire heavy mineral fractions, rather than hand selected individual zircons, in order to ensure representative random samples of zircons were analyzed. Mount imaging was conducted at the University of Michigan and the University of Arizona Laserchron Center. U-Pb analyses were conducted at the University of Arizona Laserchron Center using a laser ablation system attached to a Thermo Element 2 single collector ICP-MS (Gehrels et al., 2008; Pullen et al., 2014). Analyses > 20% discordant are excluded from further interpretation. Where practical, we analyze at least 300 zircons per sample, which provides more robust characterization of zircon age signatures than analyses with typical (n ~ 100) sample sizes (Pullen et al., 2014). In order to assess differences in detrital zircon U-Pb age distributions in this study, we use the comparative metric Bayesian Population Correlation values (Tye et al., 2019), which quantifies the correspondence between every possible pair of samples (BPC values shown in Table S3).
Description
  • The dataset contains U-Pb radiometric ages of zircon grains from sedimentary rocks and modern river sands from the Caucasus region of western Asia. The data were collected as part of a research project investigating the effects of continental collision in the Caucasus region on regional erosion and sedimentary systems. The data are presented using the standard quantities reported for zircon U-Pb age analyses at the University of Arizona Laserchron Center.
