  Description:
    Abstract: This Alaska Division of Geological & Geophysical Surveys (DGGS) Raw Data File presents 40Ar/39Ar age dating results for a volcanic whole-rock sample, selected minerals from various metamorphic rocks and igneous dikes, and white mica from both metamorphic- and hydrothermal-mineralization-related veins encountered on the southern Seward Peninsula, as well as select minerals from one plutonic rock from Cape Denbeigh, eastern Norton Sound, Alaska. Cooling ages on glaucophane, barroisite, amphibole, paragonite, and biotite from metamorphic rocks range from 84 Ma to 209 Ma. The cooling age of white mica in a possible fault zone is 144 Ma. Cooling ages on late-stage metamorphic minerals (winchite and white mica) from veins cutting foliation in metamorphic rocks range from 117 Ma to 139 Ma. Cooling ages on white mica and adularia from hydrothermal mineralization-related veins range from 105 to 131 Ma. The cooling age for one highly alkalic dike is 107 Ma. Cooling ages for younger mafic dikes range from 80 Ma to 84 Ma. The preferred age on a whole-rock sample of basalt is 0.780 +/- 0.011 Ma. Closure and cooling ages on the Cape Denbeigh granite (hornblende, K-feldspar) are 119 Ma and 113 Ma, respectively.
    Purpose: The Alaska Division of Geological & Geophysical Surveys (DGGS) Mineral Resources Section conducted geologic mapping and a mineral-resource evaluation on the southern Seward Peninsula, Alaska, during the summers of 2003, 2004, and 2006 as part of the state-funded Airborne Geophysical/Geological Mineral Inventory (AGGMI) Program. The DGGS airborne geophysical surveys, 1:50,000-scale surficial and bedrock geologic maps, and supporting geochemical and geochronologic data will foster a better understanding of the geology and mineral potential of the southern Seward Peninsula, Alaska. Additionally, as part of the Coastal Hazards program, the DGGS Engineering Geology Section collected a plutonic sample from Cape Denbeigh in eastern Norton Sound, Alaska.

  Data_Set_Credit: Collection of all but one sample was undertaken as part of the DGGS Mineral Resources section's Council project. Three summers of field work (2003, 2004, 2006) were funded through the Alaska Airborne Geophysical/Geological Mineral Inventory Program, authorized by the Alaska State Legislature and managed by the State of Alaska, Department of Natural Resources, DGGS. Supplemental funding for field work was provided by the U.S. Geological Survey (USGS) STATEMAP program (grants 04HQPA0003 and 06HQPA0003). Studies of mineral chemistry and 21 samples for 40Ar/39Ar geochronology in the Council map area were funded by Grant 04HQGR0163 from the USGS Mineral Resources External Research Program to the University of Alaska Fairbanks (UAF) (Layer and Newberry, 2004). Samples in this report were collected by Melanie B. Werdon, David J. Szumigala, Jennifer E. Athey, and Lawrence K. Freeman of DGGS, and by Rainer J. Newberry and Shelly A. Hicks of UAF Department of Geology & Geophysics. The collection of sample 2011-SKK-MD051 was funded with qualified outer continental shelf oil and gas revenues through the Coastal Impact Assistance Program, U.S. Fish and Wildlife Service (USFWS), U.S. Department of the Interior, under USFWS Grant F12AF70098. The sample was collected by Meagan DeRaps of DGGS.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: Coordinates of sample locations were determined by the geologists in the field using handheld GPS units. Sample numbers were recorded in the field on sample bags and on field note sheets. The sample location table was cross checked for consistency against the sample numbers recorded on the bags. Laboratory sample numbers were generated by the UAF geochronology, in some cases the lab numbers differ from those assigned by DGGS geologists. We provide both the lab and the DGGS sample numbers in the data tables. See text report for additional discussion of laboratory procedures. Lab results and interpretations were examined by several geologists to ensure that they are reasonable given the geologic context of the sample.
  Logical_Consistency_Report: not applicable
  Completeness_Report: Users should note that the interpretive summaries that are provided in the text report have been lightly edited for clarity but are generally provided as received from the lab.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: Location coordinates (in NAD83 for the Cape Denbeigh sample, and NAD27 datum for all other samples) were collected using handheld GPS units, with a typical reported accuracy of about 10 m or less. All location coordinates were converted to latitude and longitude (NAD1983) coordinates using ArcGIS v. 10.2.2.
  Lineage:
    Process_Step:
      Process_Description: Fieldwork - Field geologists collected rock samples from surface outcrops. Care was taken to collect fresh, unweathered samples displaying, when possible, sufficiently large grains for mineral separate sampling.
      Process_Date: 2011
    Process_Step:
      Process_Description: Sample preparation and analysis - Prior to submission to the laboratory for 40Ar/39Ar analysis, thin-sections of all samples (except for the Cape Denbeigh sample) were petrographically inspected to ensure that minerals selected for dating of magmatic crystallization were free of alteration, and that samples with white mica in veins had coarse enough white mica present for mineral separation. Rock samples that we found to be suitable for dating by 40Ar/39Ar geochronology analysis were submitted to the Geochronology Laboratory at the University of Alaska Fairbanks (UAF) where they were dated according to the protocols outlined in the accompanying report.
