Jozwik, Diana 200704 tabular digital data Raw Data File RDF 2007-1 Fairbanks, AK USA State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys 170 pp. http://www.dggs.dnr.state.ak.us/pubs/pubs?reqtype=citation&ID=15759 The geochemical analyses in this report result from the reanalysis of 932 archived stream-sediment pulps from the northern Fairbanks D-1, northern Fairbanks D-2, Fairbanks D-3 and southern Livengood A-1 and A-2 Quadrangles. The original geochemical data set included 1013 stream-sediment samples, (Albanese, 1982a-c). This publication contains unpublished geochemical data from part of geological and mineral investigations of the Fairbanks Mining District funded by the State of Alaska through the Fairbanks North Star Borough, and conducted by the Alaska Division of Geological & Geophysical Surveys (DGGS), Mineral Industry Research Laboratory (MIRL), University of Alaska and Department of Geology and Geophysics, University of Alaska Fairbanks in 1995. The samples were collected during May-July 1981. Original analyses with limited suite of elements was conducted in 1981 (Albanese, 1982a-c). The reanalysis contains a more extensive suite of elements using Instrumental Neutron Activation, Inductively Coupled Plasma and Atomic Absorption Analyses. Attribute information for the following tables (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section. Each table is listed and described in detail under its own heading starting "Entity_Type_Label." Tables include: >table1_locations locations of reanalyzed stream sediments >table2_geochem concentration of trace elements in reanalyzed stream sediments >table3_methods detection limits and analytical methods 1981 2007 publication date Complete None planned -148.50000 -147.00000 65.25000 64.75000 ISO 19115 Topic Category geoscientificInformation None Geochemical Data Geochemistry STATEMAP Project Stream Sediments Trace Elements Trace Metals None Fairbanks Fairbanks Mining District Livengood Livengood Mining District 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).

The pulps were prepared at the DGGS Geochemical Laboratory in 1981 by air-drying before screening for the -80 (180 micron) mesh fraction. After initial analysis by the DGGS lab in 1981, the pulps were stored outside the DGGS warehouse under a tarp until they were brought to the DGGS lab to be re-packaged and sent out for analysis in 1995. A suite of 34 trace elements were analyzed by Instrumental Neutron Activation Analysis (INAA) and a suite of 33 trace elements were analyzed by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) after HF-HNO3-HClO4 acid digestion with HCl leach (four-acid, near-total digestion). This method of digestion is possibly incomplete for certain elements and may result in lower analytical results. The elements with possible incomplete digestion are Ba, Cr, Ti and W. Additional partial digestion of certain elements is not known for the year 1995. Bismuth was analyzed by Atomic Absorption (AA) after hydride generation. Elements analyzed by each method and analytical detection limits are tabulated in Table 3. No topologic relationships are present in the data. This dataset contains all of the samples selected for trace-element geochemical reanalyses in the Fairbanks and Livengood quadrangles during the summer of 1981. Location data were determined by two methods: on-screen digitizing sample locations using ArcGIS v9.1 from the original field maps onto spatially registered topographic maps downloaded from Alaska Geospatial Data Clearinghouse; or using the published locations in Albanese (1982a-c). Location data (in UTM coordinates with a Clark 1866, NAD27, UTM zone 6 projection) are presented in Table 1. 100 Value in meters. The sample locations were found in the filed using a compass and altimeter. Considering the errors inherent in the USGS topographic maps, locating oneself in the field, and the methods of digitizing localities, stations, samples are located to an accuracy of between 10 and 100 meters. Prior to 1990, it is unlikely that the samples collected are accurate to more than 3 decimal places.
