  Description:
    Abstract: This Division of Geological & Geophysical Surveys (DGGS) Raw Data File presents U-Pb geochronology and Lu-Hf isotopic compositions, age-dating results, and additional trace-elemental composition of zircons from four granitoids sampled during investigations by DGGS geologists in the western Alaska Range and the Talkeetna Mountains. The purpose of the Lu-Hf and U-Pb isotopic study was to better understand the Jurassic through early Tertiary magmatic and tectonic evolution of the Alaska Range and the significance of that magmatism for the formation of metallic mineral deposits. The U-Pb isotopic data also serve to further refine the crystallization age of plutons, which were previously ambiguous in 40Ar/39Ar geochronology studies.
    Purpose: This Lu-Hf and U-Pb isotopic study was implemented to better understand the Jurassic through early Tertiary magmatic and tectonic evolution of the Alaska Range and the significance of that magmatism for the formation of metallic mineral deposits. The U-Pb isotopic data also serve to further refine the crystallization age of plutons, which were previously ambiguous in 40Ar/39Ar geochronology studies. Samples were collected in conjunction with the 2013 Styx River and 2014 Talkeetna Mountains geologic mapping and mineral resource evaluation projects.

    Attribute_Accuracy_Report: This data set is being released in the DGGS Raw Data File series. The information has been examined by several geologists familiar with the study area, but the data and accompanying report have not been formally reviewed for technical content or for conformity to the editorial standards of DGGS. Questions regarding the accuracy of information in the data files can be best answered by the originating lab.

  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: Sample location coordinates (WGS84 datum) were obtained using handheld Trimble Juno T5 GPS units, which have a typical reported accuracy of about 10 m.

    Process_Step:
      Process_Description: Fieldwork - Fresh, unweathered samples from bedrock outcrops were collected by DGGS field geologists. Sample location coordinates (WGS84 datum) were obtained using handheld Trimble Juno T5 GPS units, which have a typical reported accuracy of about 10 m. To avoid sending altered minerals for analysis, the zircon separates were further checked using binocular and optical microscopes.
      Process_Date: 2014
    Process_Step:
      Process_Description: Data analysis - Hf isotopes, U-Pb ratios, and trace-element compositions for all zircons were measured simultaneously at the University of California, Santa Barbara (UCSB) by laser ablation split-stream (LASS) analysis using the Photon Machines Analyte 193 nm excimer laser. The accompanying manuscript and data tables provide a description of laboratory procedures and applicable references.
