Online_Linkage: http://doi.org/10.14509/30439 Description: Abstract: This Alaska Division of Geological & Geophysical Surveys (DGGS) Raw Data File presents U-Pb zircon geochronology results from igneous, meta-igneous, and metasedimentary rocks collected during the Tok River and Wrangellia geologic mapping projects in the eastern Alaska Range and the northwestern Talkeetna Mountains. The purpose of these analyses is to better constrain the age of select geologic units encountered during the mapping projects. The samples were submitted to the U.S. Geological Survey, Geology, Geophysics, and Geochemistry Science Center (GGGSC)-Plasma Lab in Denver, CO where U-Pb geochronology analyses were performed by Christopher Holm-Denoma in 2016-2017. All files are available from the DGGS website: http://doi.org/10.14509/30439. Purpose: The Tok River geologic mapping project comprised the Tanacross A-5 and A-6 quadrangles. DGGS conducted fieldwork for this project during the 2015 and 2016 field seasons, and the map was published in 2017. The 2013-2015 DGGS Wrangellia project investigated the geology and mineral potential of the Wrangellia terrane in the Talkeetna Mountains and eastern Alaska Range, where recent exploration activity has targeted nickel, copper, and platinum-group-element mineralization hosted by Late Triassic mafic-ultramafic complexes, metasediment-hosted copper, porphyry copper-gold-molybdenum porphyry, and orogenic gold systems.

Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Sample-location coordinates (in WGS84 datum) were collected using handheld Trimble Juno T5 GPS units, with typical reported accuracy of about 10 meters. Location coordinates for all dated samples are provided in an accompanying .csv file in decimal-degree format, WGS84 datum. Lineage: Process_Step: Process_Description: Sample selection - Fresh, unweathered samples from surface bedrock outcrops were collected by DGGS field geologists; samples of representative rock types and important intrusive bodies were prioritized for analysis. Process_Date: 2015 Process_Step: Process_Description: Sample preparation - Zircon was concentrated using standard processing methods as described in Strong and Driscoll (2016), which included crushing, grinding, and sieving. The 500µm-44µm (standard U.S. mesh sizes 35-325) sieve fraction was then processed using a Wilfley table and a Frantz magnetic barrier laboratory separator; the non-magnetic fraction was further processed using heavy liquid (Methylene Iodide; density= 3.32 g/cm3). The concentrated non-magnetic, heavy mineral (>3.32 g/cm3 density) fraction was either hand-picked (for igneous grain mounting) or poured (for detrital zircon samples) onto two-sided tape and mounted in epoxy. Zircon in epoxy was ground to approximately half-width of the grains to expose internal portions of the grains. The zircon grains were imaged using transmitted and reflected light as well as scanning electron microscope-cathodoluminescence imaging to reveal inclusions, cracks, and growth zoning. Process_Date: 2016 Process_Step: Process_Description: Data analysis - Zircon U-Pb analyses were conducted at the U.S. Geological Survey, Geology, Geophysics, and Geochemistry Science Center (GGGSC)-Plasma Lab in Denver, Colorado. C.S Holm-Denoma analyzed zircon crystals with Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) using a Nu Instruments AttoM high-resolution, sector-field ICP-MS. Zircon were ablated with a Photon Machines Excite 193 nm ArF excimer laser in spot mode (150-200 total bursts) with a repetition rate of 5 Hz, laser energy of approximately 3 mJ, and an energy density of approximately 4.11 J/cm3. The rate of helium gas flow to the HelEx cell of the laser was 0.6 L/minute and make-up Argon gas (approximately 0.2 L/minute) was added to the sample stream prior to its introduction into the plasma. As suggested by Hu and others (2008), nitrogen with flow rate of 5.5 mL/minute was added to the sample stream, which allowed for significant reduction in ThO+/Th+ ( less than 0.5 percent) and improved the ionization of refractory Thorium. The laser spot sizes for zircon were approximately 25 μm in diameter. With the magnet parked at a constant mass, the flat tops of the isotope peaks were measured at the following masses by rapidly deflecting the ion beam: 202Hg, 204(Hg+Pb), 206Pb, 207Pb, 208Pb, 232Th, 235U, and 238U with a 30-second on-peak background measured before each 30-second analysis. Raw data were reduced off-line using the Iolite 2.5 program (Paton and others, 2011) to subtract on-peak background signals, correct for U-Pb downhole fractionation, and normalize the instrumental mass bias using external mineral standard reference materials, the ages of which have previously been determined by Isotopic Dilution-Thermal Ionization Mass Spectrometry (ID-TIMS). Ages are corrected by standard-sample bracketing with the primary zircon standard Temora2 (417 Ma; Black and others, 2004), secondary standard Plešovice (337 Ma; Slama and others, 2008), and in-house standard WRP-63-08 (1707 Ma; Wayne Premo, personal commun., 2016). Reduced data were compiled and interpreted using Isoplot 4.15 (Excel version of the procedure explained in version 3.75 manual; Ludwig, 2012).
