In conjunction with hosting field trips for the Association of American State Geologists 2016 annual meeting in Girdwood, Alaska, Alaska Division of Geological & Geophysical Surveys (DGGS) staff collected rock samples and obtained geochemical analysis from several readily accessible, but relatively unstudied outcrops. Samples were collected from Turnagain Arm (mile 104 Seward Highway), Whittier, Crow Pass, and Panorama Mountain (roughly mile 217 Parks Highway). Mineralized samples from veins and veinlets in granitic rocks from the Crow Pass and Whittier sites contain anomalous levels of gold ranging from 0.129 to 0.650 parts per million (ppm). Although none of the samples are from areas open to mineral entry, geochemical analyses of rocks from these localities may support interpretation of regional mineral-distribution trends. The analytical data tables associated with this report are available in digital format as comma-separated value (CSV) files. Additional details about the organization of information are noted in the accompanying metadata file. All files can be downloaded from the DGGS website (http://doi.org/10.14509/29725).

To comply with Alaska Railroad Corporation regulations and safely collect these samples, DGGS staff obtained written permission from the Alaska Railroad Corporation to cross the Right of Way. The sample collection and analyses were supported by State of Alaska general funds. Outcrop locations and geologic information, as well as assistance with the field trips, were provided by Sue Karl (U.S. Geological Survey), Peter Oswald (University of Alaska), and Joe Kurtak.
Location data were collected using a Nexus 5x smartphone operating the Avenza Maps 2.0 Application (AvenzaMaps.com). Location error for this process is undocumented estimated to be within 20 meters. Sample numbers were recorded in the field on sample bags and on field note sheets. The sample location tables were imported into GIS software to verify location accuracy and cross check for consistency against the sample numbers recorded on the bags. In addition to ALS Geochemistry's accredited (ISO/IEC 17025-2005) internal quality-control program, DGGS monitored analysis quality with one standard reference material per batch. Lab results were examined by the DGGS geologists to ensure that they are reasonable given the geologic context of the sample. Inconsistencies between the field data and the lab sample numbers listed on the COA (certificate of assay) are noted in the data tables. This report has not been reviewed for technical content or for conformity to the editorial standards of DGGS.

Location data were collected using a Nexus 5x smartphone operating the Avenza Maps 2.0 Application (AvenzaMaps.com). Location error for this application is undocumented, however, locations were visually checked using USGS and multiple imagery files in ArcGIS and errors are estimated to be within 20 meters. Latitude and longitude are reported in the WGS84 datum.
Sample selection - Rock samples were collected for two different purposes. First, samples of visibly mineralized or altered rock were preferentially collected and analyzed for trace-element geochemistry. Second, igneous rocks showing little alteration or weathering were collected for whole-rock major-oxide, minor-oxide, and trace-element analyses to aid in classification and study of petrogenesis and tectonic setting. All samples presented in this reports are 'select' samples, which were more deliberately collected from a specific feature, as noted in the sample field description.
2016
Sample preparation - Rock samples were processed by ALS Geochemistry using their PREP-31 package. The samples were crushed to greater than 70 percent passing 2 mm, and a 250-gram (g) split was pulverized to greater than 85 percent passing 75 microns. Prior to crushing, samples for whole-rock analysis were trimmed by DGGS staff to remove weathering, and cut surfaces were sanded to remove any saw metal.
2016
Major- and trace-element compositions - Major- and trace-element values for rock samples were determined by ALS Geochemistry method ME-MS61: Four-acid digestion followed by inductively-coupled plasma-atomic emission spectrometry (ICP-AES) and inductively-coupled plasma-mass spectroscopy (ICP-MS); Au values were determined using flux digestion and fire assay and ICP-AES (ALS Geochemistry method Au-ICP21).
2016
Whole-rock geochemistry - For whole-rock geochemistry samples, major and minor oxides were analyzed by lithium fusion digestion and ICP-AES (ALS Geochemistry method ME-ICP06). Trace elements, including rare-earth elements, were determined using lithium borate fusion digestion and ICP-MS (ALS Geochemistry method ME-MS81). Ag, Cd, Co, Cu, Li, Mo, Ni, Pb, Sc, and Zn were determined by four-acid digestion and ICP-AES (ALS Geochemistry method ME-4ACD81); and As, Bi, Hg, In, Re, Sb, Se, Te, and Tl were determined by aqua regia digestion followed by ICP-MS (ALS Geochemistry method ME-MS42). Total C and S were analyzed by Leco furnace (ALS Geochemistry methods C-IR07 and S-IR08, respectively). Au values for Whittier and Turnagain Arm samples were determined using flux digestion and fire assay and ICP-AES (ALS Geochemistry method Au-ICP21). Platinum, palladium, and gold values for the sample collected at the base of Panorama Mountain were analyzed by 30-g fire assay with ICP-MS finish (ALS Geochemistry method PGM-MS23).
