Publication_Date: 2000 Title: Interpretive bedrock geologic map of the Sagavanirktok B-1 Quadrangle, eastern North Slope, Alaska Geospatial_Data_Presentation_Form: geodatabase Series_Information: Series_Name: Report of Investigation Issue_Identification: RI 2000-1B Publication_Information: Publication_Place: Fairbanks, Alaska, United States Publisher: Alaska Division of Geological & Geophysical Surveys Other_Citation_Details: 11 p., 1 sheet, scale 1:63,360 Online_Linkage: https://doi.org/10.14509/2676 Description: Abstract: Report of Investigation 2000-1B, Interpretive bedrock geologic map of the Sagavanirktok B-1 Quadrangle, eastern North Slope, Alaska, provides 1:63,360-scale geologic mapping of the Sagavanirktok B-1 Quadrangle (640 square km equivalent to four 7.5 minute quadrangles). This mapping project reinterprets micropaleontologic correlations for 17 Sagavanirktok Quadrangle wells and reprocesses data from the one publicly-available seismic line. Surface geologic mapping, subsurface-to-surface stratigraphic age control, and seismic framework are required to reliably decipher the complex geology of this key area of the Brooks Range. Outcrops within the Sagavanirktok B-1 Quadrangle are the closest surface expressions of Prudhoe Bay source and reservoir rocks. This study yields critical petroleum-related information from these surface exposures and how they relate to the area subsurface stratigraphy. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/2676. Purpose: The Sagavanirktok B-1 Quadrangle geologic mapping project supports North Slope oil production and discovery by providing the state and industry with the first published geologic map of this part of the North Slope oil province at a scale other than 1:2,500,000. Detailed geologic mapping of the quadrangle addresses the lack of understanding of the petroleum-geology framework of the eastern North Slope, Colville basin, and the stratigraphic transition from the National Petroleum Reserve in Alaska (NPRA) to the Arctic National Wildlife Refuge (ANWR). This detailed mapping and petroleum-related data is pertinent to oil exploration for Prudhoe Bay satellite fields and new play-type reevaluations, as well as assist private-sector exploration efforts, and speed the exploration process. In addition, this data contributes to increased confidence in exploration and evaluation efforts in areas west of Prudhoe Bay.

Attribute fields within each feature class are populated using corresponding applicable values from the GeMS and AK GeMS specifications. When known, certainty in attribute interpretation is indicated in the relevant fields. Attribute accuracy varies throughout the map and is scale-dependent. Logical_Consistency_Report: All polygon features were topologically validated according to specifications of the AK GeMS geologic mapping schema. Completeness_Report: This publication is a DGGS Report of Investigations (RI). An RI is the completed product of original research and analysis, and RIs use professional cartography and undergo rigorous peer review, editing, and revision. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: This data release provides legacy geospatial data converted to the GeMS and AK GeMS specifications. To record the originating authors' degree of confidence in the location of features, the data include descriptive fields within each feature class and accompanying orientation and location confidence lookup tables. When location accuracy values are unavailable, users must infer positional accuracy based on standard geologic mapping practices of the investigation era. Field stations were located using hand-held GPS units, however for fieldwork conducted before 2000, Selective Availability limited location accuracy of the coordinates to roughly 100 meters. Certainty in feature boundaries or location varies throughout the map. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Ekberg, P.G.

Field notes and rock samples were compiled and collected throughout the Sagavanirktok B-1. Bedrock mapping involved using sources cited below. Bedrock mappers recorded observations on 1:50,000- and 1:63,360-scale topographic base maps, compiled onto a 1:50,000-scale mylar map after the field season. Field stations were located using hand-held GPS units. A comprehensive bibliographic reference list of prior work used to identify and delineate rock units and structural elements is provided in the accompanying report. Process_Date: 1999 Process_Step: Process_Description: Laboratory data compilation - Selected samples were submitted for geochronologic analysis. The results were used to further interpret the stratigraphic and structural history of the map area. Source_Used_Citation_Abbreviation: Reifenstuhl, R.R., 1991 Source_Used_Citation_Abbreviation: Reifenstuhl, R.R., 1991 Process_Date: 1999 Process_Step: Process_Description: Geologic map compilation - The geologic data were digitized from a mylar compilation of geologic field maps produced on USGS topo bases of the area. Contacts and other geologic features were determined visually using topographic maps at scales of 1:63,360 and 1:25,000, field station notes, and GPS location data. Geologic features were visually hand-plotted onto stable mylar bases from the field maps and then digitally compiled and plotted using ArcInfo software. The map and report received technical review and editing by several scientists familiar with the subject matter. The authors incorporated the reviewers' suggestions into the final draft when deemed appropriate. Process_Date: 1999 Process_Step: Process_Description: GIS analysis and digital cartography - This data distribution package's geologic and geographic features were organized and attributed according to the AK GeMS geologic mapping schema. The data were then programmatically transformed to provide download options in three formats: (1) an AK GeMS data package that includes the complete AK GeMS database and associated files, (2) a GeMS data package that is a conversion of the AK GeMS database into the base GeMS standard published by the USGS, and (3) a shapefile data package that includes two simple shapefile representations of the data.
