Lough, T.A. Freeman, L.K. Elliot, B.A. Griesel, G.A. Newberry, R.J. Szumigala, D.J. 2011 tabular digital data, report Raw Data File RDF 2011-4 Fairbanks, AK, USA State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys 118 pp. http://dx.doi.org/10.14509/23002 Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys carried out a geologic field survey, including mapping and sampling in the Moran area in the Tanana A-6 and B-6 quadrangles, and the Melozitna A-1, A2, B-1, and B-2 quadrangles, Alaska from June 17 to August 15, 2011. The fieldwork provides basic information critical to building an understanding of Alaska geology and is part of an integrated program of airborne geophysical surveys followed by geologic mapping. During 2011, 212 rock samples were collected for geochemical trace-element analysis, 58 rock samples were collected for whole-rock (major- and minor-oxide and petrogenetically important trace elements tables) analyses, and two samples were collected for analysis of non-carbonate carbon content. Additionally, 352 polished rock slabs were analyzed for whole-rock and petrogenetically important trace elements. The analyses in this report were acquired as part of a geologic mapping program, the purpose of which is to provide 1:63,360-scale geologic mapping of the Moran airborne geophysical survey released by DGGS in 2010 (Burns et al., 2010). The geophysical survey (helicopter-based aeromagnetic and electromagnetic data) and geologic mapping are part of the Alaska Airborne Geophysical/Geological Mineral Inventory Program, a special multi-year investment by the State of Alaska to expand Alaska's geologic and mineral resources knowledge base, catalyze future private-sector mineral exploration and development, and guide state resource development planning. The DGGS metadata standard extends the FGDC standard to also include several elements that are required to facilitate our internal data management. These elements (referred to as "layers") relate individual data items to a common dataset. The dataset is available in tabular format as comma delimited ascii files organized into four layers, as described in this metadata file under the "Entity_and_Attribute_Information" section. The layers are as follows: >Trace-element rock geochemistry: sample locations and descriptions, geochemical data, analytical methods and detection limits (Tables 1, 2, 3) >Whole-rock major-oxide, minor-oxide, trace-element: sample locations and descriptions, geochemical data, analytical methods and detection limits (Tables 4, 5, 6) >Non-carbonate carbon geochemistry: sample locations and descriptions, and geochemical data (Table 7) >Rock slab major-oxide, minor-oxide, trace-element: sample locations and descriptions, geochemical data, analytical methods and detection limits (Tables 8 and 9) 20110617 20110815 ground condition In work This publication is expected to be updated in fall 2011 or spring 2012. -154.735482 -152.097737 65.507439 65.107451 ISO 19115 Topic Category geoscientificInformation None Geochemical Data Geochemistry Gold Major Oxides Minor Oxides Platinum Group Elements STATEMAP Project Trace Elements Trace Geochemical Trace Metals None Alaska, State of Tanana Quadrangle Melozitna Quadrangle Moran Dome Moran Creek Yukon River Melozitna Mining District Kokrines Hills Grant Creek Little Melozitna Hot Springs None Ruby Terrane None Devonian Jurassic Cretaceous Paleozoic Proterozoic This report, map, and/or dataset are available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

Analytical methods and detection limits are listed in tables 3, 6, 7, and 9. This information is also described in the report text. Aside from ALS Chemex’s own internal quality control program, DGGS monitored analysis quality by inserting a sample of known composition into the sample roster for every batch of 20 samples. The analytical results were statistically compared to similar standard compositions for the past ~10 years. AlS Chemex results for one DGGS standard sample differed from its known composition by more than one standard deviation; mineralized samples in the same 20-sample batch were re-run for gold. These samples are listed in table 2. Analyses performed at UAF were standardized using well-characterized, natural, fine-grained rock and pure mineral standards as well as conventional pressed pellets of international rock standards. No topologic relationships are present in data. This dataset contains all of the analyses for trace-element geochemistry, whole rock (major- and minor-oxide, and trace element) geochemistry, and non-carbonate-carbon analyses for rock samples collected by DGGS in the Moran area project in 2011. Due to complications at the ALS Chemex and UAF laboratories, this data release is incomplete. Omitted sampels are noted in tables 2, 8 and 9 as "pending."We expect to release a revised report when these analyses are complete and have been quality checked. Location data were downloaded from Garmin eTrex Legend HCx GPS units into an Access database. 3 A value of estimated position error in meters was calculated by Garmin eTrex Legend HCx GPS units and recorded for each sample location. Estimated position error calculated by Garmin eTrex Legend HCx units averaged approximately 3 meters. The GPS system suffers from calculation and geometric error such as error in satellite positions, mathematical error introduced by the GPS formulas used to calculate position, and errors caused by narrow satellite alignments. Estimated position error is a value determined by the GPS manufacturer for the calculation and geometric error as a whole. 'Selective availability,' a deliberate degradation of GPS data managed by the U.S. government, was not operating during the time period these samples were collected. Fieldwork - Rock samples of visibly mineralized rock, or rock exhibiting features associated with mineralization, were preferentially collected and analyzed for geochemical trace elements. Spatially these rocks were collected randomly. Occasionally rocks exhibiting a specifc feature were selectively collected and these instances were noted in the sample description. 201107 Fieldwork - Samples for whole rock analyses (major-oxide, minor-oxide, and trace element analyses) were collected to determine 1) bulk rock composition of igneous and metaigneous lithologies, or 2) the tectonic setting of a sample’s protolith based on petrogenetically important trace elements. Unweathered or minimally weathered rock samples were preferentially selected for analysis. Spatially these rocks were collected randomly. 201107 Fieldwork - Rock samples of visibly carbonaceous or graphitic metamorphic rock were preferentially collected and analyzed for non-carbonate carbon content. Spatially these rocks were collected randomly. Unweathered or minimally weathered rock samples were preferentially selected for analysis. 201107 Sample Preparation - All sample preparation was conducted at the ALS Chemex sample preparation facility in Fairbanks, Alaska, except for preparation of whole-rock samples. Preparation of whole-rock samples was conducted at the University of Alaska Fairbanks. Rocks intended for whole-rock analysis by ALS Chemex and those with a weathering rind were trimmed at DGGS with a tile saw prior to sample preparation at the laboratory. Rock samples were crushed with a Terminator oscillating jaw crusher with chrome steel alloy plates so that at least 70 percent of the material passed through a -10 mesh (2 mm) screen. Representative aliquots of 250 grams each were taken using a stainless steel riffle splitter. These samples were then pulverized in an Essa ring mill bowl and pucks made of Essa’s Standard Steel alloy so that 85 percent of the sample passed through a -200 mesh (75 micron) screen. Trace-element analyses, whole-rock oxide analyses, and gold analyses were performed using representative splits of each 250 gram pulp. Samples for whole-rock analyses at the University of Alaska Fairbanks were cut into slabs at the Univeristy of Alaska Fairbanks or DGGS using a tile saw, and polished at the University of Alaska Fairbanks. 201109 Analysis - All potentially mineralized samples were assayed for gold by inductive coupled plasma-atomic emission spectroscopy following a 30g fire assay fusion (FA-ICP-AES). Platinum and palladium were assayed for selected samples by FA-ICP-AES. Trace-element geochemical analyses were performed by inductive coupled plasma-atomic emission spectroscopy (ICP-AES) methods after four-acid, near-total digestion. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for these elements.Analytical methods, lower and upper reporting limits, and the elements that may be affected by incomplete digestion are tabulated in table 3. Rock samples with trace metal values above the detection limit in the initial trace element geochemical analysis were reanalyzed for those metals by the following methods: gold, fire assay with a gravimetric finish using a 30g sub-sample (FA-GRAV); Posphorus, byICP-AES methods after four-acid, near-total digestion; and arsenic and/or zinc by high-grade ICP-AES methods after four-acid, near-total digestion. Results and detection limits for the reanalysis of gold, arsenic, and zinc are listed in tables 2 and 3 respectively. 201108 Analysis - Major and minor-element oxides were determined at ALS by X-ray fluorescence spectrometry following a lithium borate fusion (LBM-XRF). Trace element values for Ba, Cr, Nb, Ni, Rb, Sr, Th, U, Y, and Zr were determined by XRF on a pressed pellet.Analytical methods and detection limits are tabulated in Table 6 201109 Analysis - Non-carbonate carbon analyses were performed by ALS. Non-carbonate carbon content was determined using a LECO furnace after a dilute acid digestion. The lower detection limit for non-carbonate carbon is 0.01 percent, and the upper detection limit is 50.00 percent. 201108 Analysis - XRF spectroscopic analyses performed at UAF were standardized using well-characterized natural fine-grained rock and pure mineral standards as well as conventional pressed pellets of international rock standards. Because volatile components were not measured and rocks were of varying porosities, the analyses were normalized to 100 percent totals. In the vast majority of cases the original analyses yielded totals of approximately 95 to 102 weight percent. Comparison between these analyses and those produced on the same rocks by conventional pressed pellet (trace elements) and fused disk (major and minor oxides) techniques indicates that major- and minor-oxide and trace-element concentrations are most likely within 10 percent of the ‘true’ concentrations. Analytical methods and detection limits are tabulated in Table 9. 201109 Other - Latitude and Longitude values in Tables 1,4,7 and 8 were converted from UTM values with the "project" tool in the "data management" toolbox in ArcGIS Desktop 10.0 using ArcMap 10.0. 201110 Point Universal Transverse Mercator 5 0.9996 -153 0 500000 0 coordinate pair 5 11 meters Trace-element rock geochemistry Universal Transverse Mercator 5 0.9996 -153 0 500000 0 coordinate pair 5 11 meters Whole-rock major-oxide, minor-oxide, trace-element Universal Transverse Mercator 5 0.9996 -153 0 500000 0 coordinate pair 5 11 meters Non-carbonate carbon geochemistry Universal Transverse Mercator 5 0.9996 -153 0 500000 0 coordinate pair 5 11 meters Rock slab major-oxides, minor-oxides, and trace-elements North American Datum of 1927 Clarke 1866 6378137 298.25722210088 Trace-element rock geochemistry Table1.csv Location and description of rocks collected for trace metal geochemistry in the Moran area, Tanana and Melozitna quadrangles, Alaska Alaska Division of Geological & Geophysical Surveys Sample Number Unique sample identifier Alaska Division of Geological & Geophysical Surveys Generic example of unique sample identifier: 20YYAAA9999X: YY=last two digits of year, AAA=geologist's initials (one to three characters), 9999=unique station number, X=unique alpha character designating a sample was taken at the field station.
