This report and digital data release presents 12 new geochemical analyses on historic U.S. Bureau of Mines (USBM) samples, including 6 rock, 4 stream sediment, and 2 heavy mineral concentrate (pan concentrate) samples. These samples were originally collected by the USBM to follow up reported tungsten anomalies in the VABM Bend area, Charley River and Eagle quadrangles, east-central Alaska. Historic USBM sample materials were retrieved by DGGS from the DGGS Geologic Materials Center (GMC), where the USBM samples were transferred as part of the federally funded Minerals Data and Information Rescue in Alaska (MDIRA) program in the late 1990s and early 2000s. The text and analytical data and tables associated with this report are being released in digital format as PDF files and .csv files. We provide analytical data, detection limits and, when available, the method documentation provided to us by the lab. We also provide the sample location in geographic coordinates, the sample material cited by the originating literature, a reference to the originating report, and the type of sample material that was obtained from the archive and sent to the lab.
The State of Alaska's Strategic and Critical Minerals (SCM) Assessment project, a state-funded Capital Improvement Project (CIP), designed to evaluate Alaska's statewide potential for SCM resources. The SCM Assessment project 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 project, thousands of historic geochemical samples from the DGGS, U.S. Geological Survey, and U.S. Bureau of Mines (USBM) archives are being re-analyzed by DGGS using modern, quantitative, geochemical-analytical methods. The objective is to update the State of Alaska's statewide digital geochemical database in order to more clearly identify areas with SCM potential.
The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management. These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships and correspond to subdirectories within the data distribution package. The metadata layer provides an FGDC metadata file and may include other documentation files. Attribute information for each data layer is described in this metadata file under the "Entity_and_Attribute_Information" section. Data layer contents:
>border: A polygon that encompasses the maximum geographic extent of the data observations
>trace-element-ree: Table with modern analyses of historic samples for geochemical trace-elements and rare-earth-elements and a table of analytical detection limits for each element

Analytical results obtained from samples submitted to geochemical laboratories must pass through two levels of data validation. The first level of quality control checks occurs at ALS, which is accredited to ISO/IEC 17025-2005 standards. The laboratory's quality control protocol is to insert a reagent blank and a reference sample material with every batch of 20 samples to measure the analytical accuracy. Duplicate samples are analyzed at the end of the sample set to measure analytical variance as well as sample variance. Data passing the quality control criteria are sent to DGGS. The second level of data validation is performed by DGGS. All samples submitted to ALS are accompanied by a variety of DGGS in-house, ore-geochemical reference samples (blinds) submitted at the rate of 1, or occasionally more than 1, per sample batch. Upon receipt of analyses from the lab, reference standards are checked by DGGS against their accepted values. If present, any batches with reference standards with elemental values falling outside 2 standard deviations of their accepted values were submitted to the lab to be reanalyzed. For each sample, data tables either contain assay values, or they contain coded-value place holders (that is, null = 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). We provide detection limits and, when available, the method documentation provided to us by the lab. Users should contact the originating lab for additional information about detection limits and reporting procedures. We obtained geographic coordinates and the original sample material from the originating literature. We also note the type of sample material that was obtained from the archive and sent to the lab. The reported sample weights were measured by DGGS staff and are considered to be more accurate than the weight values listed on the ALS Certificate of Assay. Samples were sent to ALS in multiple batches and the method used varies between batches. In some cases, the method used may not provide quantitative results for all elements. The analyses presented in this publication were generated as a component of a broader project in which five batches of samples were sent to ALS. In a few cases samples were reanalyzed using several different methods, consequently, each analysis is uniquely identified by the combination of sample number + laboratory batch number.
not applicable
This dataset is complete.
Location data for each sample were derived by DGGS staff by scanning station-location map figures from USBM reports, georegistering the map figures in ArcGIS v. 10.1, creating a point layer of station locations, and extracting latitude-longitude coordinates. Although ArcGIS can provide precise location coordinates, users should consider both possible errors intrinsic to how the historic locations were originally collected as well as error inherent in scanning and digitizing locations from a printed map. Location data for each sample are presented in latitude and longitude coordinates in decimal degrees with NAD27 datum and Clarke 1866 spheroid.

Sample preparation - Sample pulps were retrieved from the GMC, examined, and split by DGGS staff into aliquots needed for the analyses, with leftover portions of the pulps saved and stored at the GMC. Splits of pulps were submitted to ALS Minerals Laboratories (ALS) for analysis. Where pulps were unavailable, coarse-reject material was prepped by ALS using method PUL-31: pulverize split to 85 percent less than 75 microns. Coarse-reject samples were pulverized at ALS using "flying disk" or "ring and puck" style, low chrome, steel grinding mills. A sample split or total sample up to 250 g is pulverized, with 85 percent of the resulting material passing through a screen of 75 microns.

Method ME-MS81 38-element, fusion, ICP-MS - For all samples, trace elements, including rare-earth elements, were determined using lithium metaborate fusion digestion and ICP-MS (ALS Minerals method ME-MS81). A prepared sample (0.200 g) is added to lithium metaborate flux (0.90 g), mixed well and fused in a furnace at 1,000ÃÂðC. 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). Note: Some base-metal oxides and sulfides may not be completely decomposed by the lithium borate fusion. Results for Ag, Co, Cu, Mo, Ni, Pb, and Zn will not likely be quantitative by this method.
2013
Method ME-ICP61 33-element, 4-acid, ICP-AES - A prepared sample (0.25 g) is digested with perchloric, nitric, hydrofluoric, and hydrochloric acids. The residue is topped up with dilute hydrochloric acid and the resulting solution is analyzed by inductively coupled plasma-atomic emission spectrometry (ICP-AES). Results are corrected for spectral inter-element interferences. Note: Four-acid digestions are able to dissolve most minerals, however, although the term "near total" is used, depending on the sample matrix, not all elements may be quantitatively extracted.
2013
Method ME-MS61 48-element, 4-acid, ICP-AES or ICP-MS - A prepared sample (0.25 g) is digested with perchloric, nitric, hydrofluoric, and hydrochloric acids. The residue is topped up with dilute hydrochloric acid and the resulting solution is analyzed by inductively coupled plasma-atomic emission spectrometry (ICP-AES). Results are corrected for spectral inter-element interferences. Note: Four-acid digestions are able to dissolve most minerals, however, although the term "near total" is used, depending on the sample matrix, not all elements may be quantitatively extracted.

Method PGM-ICP23 Pt, Pd, Au, 30-gram, FA-ICP-AES - Gold (Au), platinum (Pt), and palladium (Pd) values were obtained from a prepared, 30 g sample, fused with a mixture of lead oxide, sodium carbonate, borax, and silica, inquarted with 6 mg of gold-free silver, and then cupelled to yield a precious-metal bead. The bead is digested for 2 minutes at high power by microwave in dilute nitric acid. The solution is cooled and hydrochloric acid is added. The solution is digested for an additional 2 minutes at half power by microwave. The digested solution is then cooled, diluted to 4 mL with 2% hydrochloric acid, homogenized, and then analyzed for gold, platinum, and palladium by inductively coupled plasma-atomic emission spectrometry (ICP-AES).
