Online_Linkage: http://dx.doi.org/10.14509/29452 Description: Abstract: The State of Alaska's Strategic and Critical Minerals (SCM) Assessment project, a State-funded Capital Improvement Project (CIP), is designed to evaluate Alaska's statewide potential for SCM resources. The SCM Assessment is being implemented by the Alaska Division of Geological & Geophysical Surveys (DGGS), and involves obtaining new airborne-geophysical, geological, and geochemical data. For the geochemical part of the SCM Assessment, thousands of historical geochemical samples from DGGS, U.S. Geological Survey (USGS), and U.S. Bureau of Mines archives are being reanalyzed by DGGS using modern, quantitative, geochemical-analytical methods. The objective is to update the statewide geochemical database to more clearly identify areas in Alaska with SCM potential. For this report, DGGS funded reanalysis of 1,682 historical USGS sediment samples from the statewide Alaska Geochemical Database Version 2.0 (AGDB2; Granitto and others, 2013). Samples were chosen from an area covering Tonsina area, Valdez Quadrangle, Alaska. USGS was responsible for sample retrieval from the Denver warehouse through the final quality assurance/quality control (QA/QC) of the geochemical analyses obtained through the USGS contract lab. The new geochemical data are published in this report as a coauthored DGGS report, and will be incorporated into the statewide geochemical databases of both agencies. Purpose: The State of Alaska's Strategic and Critical Minerals (SCM) Assessment project, a State-funded Capital Improvement Project (CIP), is designed to evaluate Alaska's statewide potential for SCM resources. The SCM Assessment is being implemented by the Alaska Division of Geological & Geophysical Surveys (DGGS), and involves obtaining new airborne-geophysical, geological, and geochemical data. As part of the SCM Assessment, thousands of historical geochemical samples from DGGS, U.S. Geological Survey (USGS), and U.S. Bureau of Mines archives are being reanalyzed by DGGS using modern, quantitative, geochemical-analytical methods. The objective is to update the statewide geochemical database to more clearly identify areas in Alaska with SCM potential.

Where a numerical suffix is shown, this element was analyzed by more than one method. In the detection-limits table and the metadata file, documentation is provided to explain each field name, as well as additional details such as lab name and method codes, analytical-method types and documentation, and the upper and lower detection limits for each of the elements and methods. For a few elements, the laboratory reported values that are either above the upper detection limit or below the lower detection limit; these values were kept in the data table. For each element, for each sample, the analytical-data table either contains assay values, or it contains coded-value place holders (that is, null or blank = not analyzed; -1 = the element's assay result is less than the lower detection limit for the method; -2 = the element's assay result is greater than the upper detection limit for the method; -3 = composition of this sample makes detection impossible by this method; interference problems; -4 = sample was submitted to the laboratory, but insufficient sample material was available to conduct an analysis). Logical_Consistency_Report: not applicable Completeness_Report: The sediment samples of interest were collected as part of several USGS and U.S. Department of Energy projects. Details of initial sample collection and analytical methods for these historical samples have been compiled into a single digital database, AGDB2 (Granitto and others, 2013). The original analyses for most of these samples were previously published, and the citations for the original results are included in the References and Original Data Sources section of the accompanying report. This publication provides results for all samples that were analyzed for this project. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data for each sample are presented in latitude and longitude coordinates in decimal degrees with NAD27 datum and Clarke 1866 spheroid; resolution is variable, and ranges from 5-digit GPS precision to others with less precision. Original locations were collected with NAD27 datum and Clarke 1866 spheroid; original location information is documented in Granitto and others (2013).

DGGS converted the coordinates for these samples to NAD27 datum and Clarke 1866 spheroid using appropriate transformations in ArcGIS; original location information is documented in Granitto and others (2013). Source_Used_Citation_Abbreviation: Granitto, Matthew and others, 2013 Process_Date: 2014 Process_Step: Process_Description: Sample preparation - Historical sediment samples were retrieved from the National Geochemical Sample Archive (NGSA) in Denver, Colorado, by USGS staff, then weighed, ground to -200 mesh and, where sufficient material was available, split into aliquots needed for analyses. Leftover material was re-archived at the NGSA. Sample splits were submitted to the USGS contract lab (SGS Minerals Services, Lakefield, Canada) for analysis. Process_Date: 2014 Process_Step: Process_Description: Method 20: Gold (Au), Platinum (Pt), and Palladium (Pd) - Gold, Pt, and Pd content were determined in geologic materials by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) after collection by fire assay. An assay ton (30 grams) was weighed into a crucible with 150 grams of flux and mixed. One mg of silver nitrate was added and covered with borax, and then placed in the furnace for 45 minutes at 1,080 degrees C. The melt was poured into a cast-iron mold, cooled, and hammered to free the lead button from the slag. The lead button was placed on a cupel and heated at 950 degrees C until all the lead was removed. The resulting dore bead was dissolved in a mixture of nitric acid and hydrochloric acid and heated in a water bath. The final solution was adjusted to 10 ml and introduced into the ICP-MS. The lower reporting limits are 1 ppb for Au and Pd, and 0.5 ppb for Pt. The upper limit for all elements is 10,000 ppb. Data were deemed acceptable if recovery of gold, platinum, and palladium was +/-20 percent at five times the lower limit of detection (LOD) and the calculated Relative Standard Deviation (RSD) of duplicate samples was no greater than 20 percent. Process_Date: 2014 Process_Step: Process_Description: Method 22: 55-Element ICP-AES-MS sodium peroxide sinter - Fifty-five major (except Si and Na), rare-earth, and trace elements were determined in geologic materials by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and ICP-MS. The 0.10 g sample was decomposed using a sodium-peroxide sinter at 450 degrees C. The resultant cake was leached with water for a minimum of 4 hours, and acidified with nitric acid. After an addition of tartaric acid, aliquots of the digested sample were aspirated into the ICP-AES and the ICP-MS. The concentrations of the optimal elements from the ICP-AES and ICP-MS were determined. Calibration on the ICP-AES was performed by standardizing with digested rock reference materials and a series of multi-element solution standards. The ICP-MS was calibrated with aqueous standards, and internal standards were used to compensate for matrix effects and internal drifts. Reporting limits for the 55 elements are presented in the tables accompanying this report. Data were deemed acceptable if recovery for all 55 elements was +/-15 percent at five times the lower LOD and the calculated RSD of duplicate samples was no greater than 15 percent. Process_Date: 2014 Process_Step: Process_Description: Method 13: Tellurium (Te) - Tellurium content was determined by weighing 0.25 g of sample into a Teflon tube, adding a mixture of nitric, hydrofluoric, and perchloric acids and heating the sample. After the solution cooled, hydrochloric and nitric acids were added, and the sample was heated again, and then cooled. The samples were diluted and analyzed using hydride-generation atomic absorption spectrometry with an auto-analyzer and automated data collection system from Labtronics. The lower reporting limit for Te is 0.5 ppm and the upper detection limit is 1,000 ppm. Data for Te were deemed acceptable if recovery of that element was +/-20 percent at five times the lower LOD and the calculated RSD of duplicate samples was no greater than 20 percent.
