Why was the data set created?

The State of Alaska's Strategic and Critical Minerals (SCM) Assessment project, a State-funded Capital Improvement Project, 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 throughout Alaska. DGGS also collected and geochemically analyzed 114 rock samples from mafic and ultramafic rocks to evaluate the Tonsina area's potential for platinum-group elements, nickel, and chromium.

How was the data set created?

1. From what previous works were the data drawn?

2. How were the data generated, processed, and modified?

   Date: 2015 (process 1 of 5)

   Sample collection - Rock samples were collected for two different purposes. Samples of sulfide- or chromite-bearing rocks, or altered rocks, were preferentially collected and analyzed for trace-element geochemistry. Most samples are "grab" samples, which were randomly collected at a location; however, a few samples are "select" samples, which were deliberately collected from chromite-rich layers in ultramafic rocks. 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. These igneous rocks were also analyzed for trace-element chemistry, as some of the samples contain sulfide(s) and (or) chromite.

   Date: 2015 (process 2 of 5)

   Sample preparation - Rock samples were processed by ALS Minerals using their PREP-31 package. The samples were crushed to better than 70 percent passing 2 mm, and a 250 g split was pulverized to better 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.

   Date: 2015 (process 3 of 5)

   Major- and trace-element compositions - Forty-eight major- and trace-element compositions for rock samples were determined on a 1 g sample (ALS Minerals method ME-MS61) using a four-acid digestion followed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and ICP-MS. Samples that exceeded detection limits for elements of interest were reanalyzed using specific elemental tests. For this report, samples with over-limit values for chromium (Cr) were reanalyzed using a 0.5 g split using four-acid digestion with ICP-AES (ALS Minerals procedure Cr-OG62).

   Date: 2015 (process 4 of 5)

   Platinum, palladium, and gold values - Platinum, palladium, and gold values were analyzed by 30 g fire assay with inductively coupled plasma-mass spectroscopy (ICP-MS) finish (ALS Minerals method PGM-MS23) for all samples.

   Date: 2015 (process 5 of 5)

   Whole-rock geochemistry - Whole-rock geochemistry samples were analyzed using ALS Minerals complete whole-rock characterization package (CCP-PKG01) on a 10 g split. Major- and minor-oxide values were determined using lithium metaborate fusion digestion and ICP-AES (ALS Minerals method ME-ICP06). Relatively resistive trace elements, including rare-earth elements, were determined using a lithium borate fusion digestion and ICP-MS (ALS Minerals method ME-MS81); Ag, Cd, Co, Cu, Li, Mo, Ni, Pb, Sc, and Zn were determined by four-acid digestion and ICP-AES (ALS Minerals method ME-4ACD81); and As, Bi, Hg, Sb, Se, and Te were determined by aqua regia digestion followed by ICP-MS (ALS Minerals method ME-MS42). Total C and S were analyzed by Leco combustion furnace (ALS Minerals method ME-IR08).

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

   Analytical results obtained from samples submitted to the contract laboratory (ALS Minerals) must pass through two levels of data validation. The first level of quality control checks occurs at ALS Minerals. ALS Minerals is accredited to ISO/IEC 17025:2005 standards and conforms to requirements of CAN-P-4E and CAN-P-1579 (Standards Council of Canada, 2015). 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 at DGGS. All samples submitted to ALS Minerals were accompanied by a set of DGGS in-house, mineralized, and whole-rock reference samples (blinds) submitted at the rate of 1-2 per 20-sample batch. The data for the reference samples are evaluated by comparing the obtained analytical value to the expected value for each element. The values must fall within the range of acceptance, which varies between +/-5 percent and +/-20 percent depending on the analytical method. Samples associated with rejected quality control data are reanalyzed by ALS Minerals. No samples were associated with rejected quality control data in this study, and therefore no samples were reanalyzed.

2. How accurate are the geographic locations?

   Location data for each sample were collected using a Garmin eTrex HC Series GPS (in 2014) and a Garmin GPSmap 62 GPS (in 2015), and are presented in latitude and longitude coordinates in decimal degrees with NAD27 datum and Clarke 1866 spheroid. Uncertainty of positional accuracy is considered to be less than 10 m for these GPS units.

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

   This data release is complete. The data tables have been lightly edited for clarity, but are generally provided as received from the lab.

5. How consistent are the relationships among the observations, including topology?
