All materials were analyzed by ALS Global, between 2014 and 2020, by a range of different techniques, so multiple unique entries for a given element relate to different analytical methods or preparations, as detailed in accompanying metadata. This data setwas developed from samples collected during geological mapping and research conducted from 2013 to 2019, including a mix of surficial and drill-core material. The geochemical data from igneous and metamorphic rock samples aid in the interpretation of possible tectonic environment, melting sources, and crystallization history. These data contribute to understanding the geologic history of the Alaska Range. Sample collection was funded by the Mineral Resources Program of the U.S. Geological Survey.

Methods used for sample preparation of geochemistry analyses by ALS between 2014 and 2020. Prior to crushing, samples for whole-rock analysis were trimmed by USGS staff to remove weathering or heterogeneities, and cut surfaces were lapped to remove any saw metal. Sample material is crushed to >70% passing 2 mm, and a 250 g split is then pulverized in low-chrome steel grinding mills to >85% passing 75 microns, with barren material passing through pulverizers between each sample. Approximately 3-5g aliquots of USGS standard reference materials (AGV2 - andesite, BHVO2 – basalt, DNC1 - dolerite, DTS2b - dunite, GSP2 - granodiorite, QLO1 - quartz latite, W-2 - diabase), plus two internal standards (12AJJ39E, 12AJJ46A) were submitted as unknown samples to monitor accuracy, and replicates of seven of these (AGV2, BHVO2, DNC1, GSP2, and W2, plus the two internal standards) were run in different sessions to monitor laboratory reproducibility. 'Field_Name' in file "geochemistry_igneousMetamorphic_dataDictionary_yukonTanana_2022_todd.csv" provides element (or element oxide), unit (% versus ppm/ppb), and a subscript composite indicating the analytical method. The method subscript begins with "ME_" and is followed by a method code, which refers to analytical packages, each with varying decomposition and analytical techniques, and are described as subsequent Process Steps. Unknown "XRF26" – A calcined or ignited sample (0.9 g) is added to 9.0g of lithium borate Flux (50 % - 50 % Li2B4O7 - LiBO2), mixed well and fused in an auto fluxer between 1050 - 1100°C. A flat molten glass disc is prepared from the resulting melt. This disc is then analyzed by X-ray fluorescence (XRF) spectrometry. Unknown "OA_GRA05x" – The total oxide content is determined from the XRF analyte concentrations and loss on Ignition (L.O.I.) values. A prepared sample (1.0 g) is placed in an oven at 1000°C for one hour, cooled and then weighed. The percent loss on ignition is calculated from the difference in weight. Unknown "ICP06" – A prepared sample (0.200 g) is added to lithium metaborate/lithium tetraborate (LiBO2 /Li2B4O7) flux (0.90 g), mixed well and fused in a furnace at 1000°C. The resulting melt is then cooled and dissolved in 100 mL of 4% nitric acid/2% hydrochloric acid. This solution is then analyzed by inductively coupled plasma atomic emission spectroscopy (ICP-AES) and the results are corrected for spectral inter-element interferences. Oxide concentration is calculated from the determined elemental concentration and the result is reported in that format. Unknown "GRA05" - The total oxide content is determined from the ICP analyte concentrations and loss on ignition (L.O.I.) values. A prepared sample (1.0 g) is placed in an oven at 1000°C for one hour, cooled and then weighed. The percent loss on ignition is calculated from the difference in weight. Unknown "MS81" - A prepared sample (0.200 g) is added to lithium metaborate flux (0.90 g), mixed well, and fused in a furnace at 1000°C. The resulting melt is then cooled and dissolved in 100 mL of 4% HNO3 / 2% HCl3 solution. This solution is then analyzed by inductively coupled plasma - mass spectrometry (ICP-MS). Unknown "4ACD81" - Prepared sample (0.25 g) is digested by four (perchloric, nitric, hydrofluoric, and hydrochloric) acids, suitable for the determination of base metals since many sulfides and some metal oxides are only partially decomposed by the borate fusion and some elements such as cadmium and zinc can be volatilized. Not suitable for mercury determination (Aqua Regia digest preferred). This solution is then analyzed by ICP-MS. unknown "MS42" - Prepared sample (0.25 g) is digested with Aqua Regia (nitric and hydrochloric acids), suitable for the determination of most base metals since many sulfides and some metal oxides are only partially decomposed by the borate fusion and some elements such as cadmium and zinc can be volatilized. Not suitable for nickel and cobalt determination (four acid digest preferred). This solution is then analyzed by ICP-MS. unknown "MS61" – Prepared sample (0.25g) is digested with HNO₃-HClO₄-HF, and an HCl leach, dissolving nearly all minerals in most geological samples. The resulting salt is dissolved in 100 mL of 4% HNO3 / 2% HCl3 solution. This solution is then analyzed by inductively coupled plasma - mass spectrometry (ICP-MS). unknown "MS61L" - Same as MS61 (Process Step 9), but with improved lower detection limits. unknown "ICP21" - Au by fire assay and ICP-AES, 30g nominal sample weight. unknown "MS25NS" - Nickel sulphide collection fire assay and ICP-MS finish. 30g nominal sample weight. unknown "XRF05" - A finely ground sample powder (10 g minimum) is mixed with a few drops of liquid binder (Polyvinyl Alcohol) and then transferred into an aluminum cap. The sample is subsequently compressed under approximately 30 ton/in^2 in a pellet press. After pressing, the pellet is dried to remove the solvent and analyzed by WDXRF spectrometry. unknown "OG62" - NI by HF-HNO3-HClO4 digestion (0.4g sample) with HCl leach, ICP-AES finish; run by default when Ni_ppm_ME_MS41 determination is over limit. unknown Point 0.0001 0.0001 Decimal degrees World Geodetic System of 1984 (WGS84) World Geodetic System of 1984 (WGS84) 6378137 298.257223563 geochemistry_igneousMetamorphic_dataDictionary_yukonTanana_2022_todd.csv Table outlining the contents of table "geochemistry_igneousMetamorphicWholeRock_yukonTananaUpland_2022_todd.csv", with field names, descriptions, and upper/lower detection limits for analyses, as applicable.

This table contains 790 entries and is presented in comma separated value (.csv) format. Author defined Index Numeric identifier used for sorting purposes within this table only. Author defined 1 790 Sample Sample number as collected in the field or established standard identifier; this is either a USGS or laboratory specific alphanumeric identifier. Author defined Sample identifier; most labels consist of the last two digits of the year collected, an abbreviation identifying the sample collector, and a number and possible suffix. Sample identifiers for established standard reference materials are also noted; these may be repeated over multiple analyses as a check for accuracy and reference for laboratory reproducibility. Core sample names generally include a one or two letter code for site, the last 2 digits of the year drilled, and down-hole core depth interval, although formatting and depth units vary from site to site. All are presented here as originally recorded, without units used, for consistency with other occurrences of these materials in other sources. Report Geochemistry report number, generated by analytical contractor; First two digits following the letters 'FA' refer to last two digits of calendar year of analysis. Author defined Values listed here are identifiers created by the analytical contractor that contain alphanumeric sequences denoting a specific report of analysis completed within a calendar year. Unit Tentative geological map unit inferred for each sample, using the simplified map units from Wilson et al. (2015). These unit designations are provided for informational purposes only, to aid in the interpretation of these data. In some cases, sample units are inconsistent with map unit at their location. In these instances, the unit designation is based on a combination of the field interpretations made by individual researchers during new mapping and collection of these samples, and the availability of new UPb ages (Todd et al., 2019; Jones and O'Sullivan, 2020; Todd and Kylander-Clark, 2022; Holm-Denoma et al., 2022). Units listed here are the Map unit labels from Wilson et al. (2015), with some exceptions. First, we do not make a distinction between KJgu and Kmgr, presuming all samples within either are mid-Cretaceous, and are all labeled here as Kmgr. Second, new unit codes are added here, one each for Permain and early Tertiary plutons (Pmg, Tp, respectively). Neither Permian nor a locally appropriate Tertiary plutonic units are described in the referenced map, and the only local early Tertiary unit is volcanic (Tv). And third, several plutonic igneous samples included here are located with unit TKpr, a mapped late-Cretaceous pyroclastic unit in Wilson et al. (2015), so we apply the less-common TKgi (intrusive) unit label to these. Author defined Values listed here are alphanumeric designators indicating geologic age and lithology abbreviations. This field does not contain unique values, as several samples may be grouped together within a geologic unit designator for more broad source analysis.
