Publication_Date: 2007 Title: Geologic Map of the Siksikpuk River Area, Chandler Lake Quadrangle, Alaska Geospatial_Data_Presentation_Form: vector digital data Series_Information: Series_Name: Preliminary Interpretative Report Issue_Identification: PIR 2007-1 Publication_Information: Publication_Place: Fairbanks, Alaska - USA Publisher: State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys Other_Citation_Details: 1 sheet, scale 1:63,360 Online_Linkage: http://dx.doi.org/10.14509/15757 Description: Abstract: During 2004 and 2005 DGGS Energy Section geologists, together with University of Alaska Fairbanks and USGS personnel, conducted 1:63,360-scale geologic mapping in the Siksikpuk River Area of the Chandler Lake B-4 and C-4 quadrangles in northern Alaska. This work was conducted as part of the USGS-funded STATEMAP project, part of the National Cooperative Geologic Mapping Program. Purpose: This portion of the northern Brooks Range foothills is thought to be strategic for natural gas in particular, and is currently under lease to both major and smaller independent petroleum exploration companies. New mapping in this area provides an opportunity to study, in outcrop, the stratigraphy and structural styles of the source and reservoir rocks that enrich the Colville basin to the north. The mapping extends structural and stratigraphic models developed during previous mapping along the foothills to the west, providing baseline geologic data to the private and public entities that identify, develop, and manage resources that area.

Attribute information for the following layers (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Geologic point, line, and polygon data were determined visually using color infrared aerial photographs at a scale of approximately 1:63,360 and topographic maps at scales of 1:63,360 and larger. The geospatial data included in this project are digitized from a Mylar compilation of geologic field information produced on USGS topographic base maps of the area. AAAGES font was used to display geologic age symbols. Geologic data included in the compilation are the field maps and notes from this project. Feature attributes were checked by the geologists who made the field observations. To check attribute accuracy, a check plot was visually compared to the geologist's original compilation. Discrepancies between the digital geospatial dataset and the original analog or digital compilation were corrected as needed. Logical_Consistency_Report: Polygon topology is present on appropriate geospatial data; others are line or point data. Completeness_Report: This dataset includes geospatial information about beds traceable on air photos and/or in the field, geologic units and contacts, fold and fault traces, strike, dip, and fold axis attitude, the trace of the Lisburne phosphate outcrop, and planar structure orientations. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Locations were determined in the field using raster images of topographic base maps and Garmin GPS units. Data were mapped directly on scale-stable copies of the topographic base maps and digitized using heads-up monitor display and a mouse. Point data were plotted directly from the GPS data. Most digitized positions on the map are estimated to have better than 5 m horizontal accuracy. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Kelley, J.S.

Process_Step: Process_Description: Fieldwork - Geologic mapping took place during three-week field seasons during June-July 2004 and 2005. Mappers recorded observations in field notebooks and on the aerial photographs and topographic maps, predominantly at 1:63,360 scale. Bedrock mapping involved using aerial photographs and topographic maps on a daily basis for checking geologic contacts and units. All compilations were made by hand on stable mylar at 1:63,360 scale. Stations were located using aerial photographs, topographic maps, and altimeters. In most instances, GPS devices were used. Stations were also plotted by hand on stable mylar topographic bases and coordinates determined by digitizing.

Data were compiled on multiple layers of stable mylar at 1:63,360 scale. Relevant information from all mylar layers was compiled onto one stable mylar sheet with abundant control points. This mylar was then scanned and digitized.
