The area is part of the Manley Hot Springs-Tofty mining districts and adjacent to the Rampart mining district to the north of the Tanana A-1 and A-2 Quadrangles. This report includes detailed bedrock, structural, stratigraphic, and geochronologic data. Based on the resulting geologic maps, field investigations, and laboratory materials analyses, the project has also generated derivative maps of geologic construction materials and geologic hazards. Purpose: The Tanana B-1 quadrangle lies between the villages of Rampart, on the Yukon River, and Manley Hot Springs, at the terminus of the Elliot Highway. At the time this project was published the area towns were not part of any municipal or local governmental jurisdiction. The investigation of gold, tin, and other mineral occurrences in conjunction with comprehensive geologic mapping and recently acquired geophysical data will pro­vide a scientific basis for continued mineral exploitation that will economically benefit the region's inhabitants and the State of Alaska. This publication also identifies sources of construction materials and evaluates the type and severity of geologic constraints to future development in the region.

Geologic data included in the compilation are the field maps and notes from this project as well as data from other sources as noted in the "Sources Cited" section. Attributes were verified for consistency and completeness during the creation of the metadata. Logical_Consistency_Report: Polygon topology present and clean on appropriate data. Other data are line, point, or annotation data and do not require topologic relationships. Completeness_Report: This dataset includes geospatial information about geologic units and their ages; field sample locations; structural features; and structural measurements. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: DGGS location data and estimated position errors were manually entered into a spreadsheet. Sample numbers and locations with selected data were spatially registered and analyzed in ArcGIS software. See "Source_Information" section for horizontal positional accuracy of locations not measured by DGGS. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 100 Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters was calculated by the GPS units and recorded for each sample location. This error results from items such as error in satellite positions, mathematical error introduced by the formulas used by the GPS unit for calculating 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 that induces an additional error of approximately 100 meters to a GPS location, was in effect until May 1, 2000, and thus during the time of this field work. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 110 Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters. The bedrock field maps were digitized using a map tablet and cross-hair mouse. Map error is induced by: (1) transferring map data from base topography to a mylar compilation map, with an estimated potential error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; (2) the digitizing RMS error [24 control points on a regular grid have an average RMS error of 10.8 meters on the ground; individual control point error ranges from 4.3 to 21.2 meters on the ground]; and (3) the accuracy of the human operator digitizing the geologic line work from the topographic base map, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground. Total potential horizontal error for bedrock and comprehensive geologic map features is estimated to be approximately 110 meters.

Process_Step: Process_Description: Field work - Field work for bedrock investigations, including ridge traverses and examination of riverbank exposures, was conducted between April 30 and July 4, 1996. Field notes and rock samples were collected at approximately 700 stations throughout the Tanana A-1 and A-2 Quadrangles. Bedrock mappers recorded observations on 1:50,000- and 1:63,360-scale topographic base maps, compiled onto a 1:50,000-mylar map after the field season ended. Field stations were located using hand-held GPS units. Field station notes and GPS location data were manually entered into a spreadsheet. Process_Date: 1996 Process_Step: Process_Description: Laboratory data - See paper reports RI 97-15A and RI 97-15B for more information. Process_Date: 1996 Process_Step: Process_Description: Digital Cartography - Bedrock point data of locations of structural observations (strike, dip, cleavage, jointing, etc.) were intersected with the surficial-geologic polygon coverage using the Arc command "intersect" in order to identify locations that were mapped as surficial materials based on aerial photography but were found to have small exposures that were desirable to be mapped as bedrock. These areas were then modified in the surficial-geologic coverages to be areas of bedrock exposure. Final bedrock and surficial geology polygon coverages were merged using the Arc command "union" to generate the polygon coverage used to make the comprehensive geologic map. Other cartographic elements, primarily text and tables, were created in CorelDraw, converted to CGM format, and imported into ArcPlot for final layout.
