This geologic map and report supersede the previously released Public Data File 99-24B, Preliminary interpretive bedrock geologic map of the Healy A-6 Quadrangle, southcentral Alaska. The current map has been updated to include mapping of areas adjacent to the Healy A-6 Quadrangle, newly interpreted bedrock units based on newly acquired analytical, paleontologic, and Ar40/Ar39 data. Ages for the rock units were modified. Field investigations were part of a two-year mapping program to provide geologic ground truth for airborne geophysical surveys flown by DGGS in the Chulitna region of southcentral Alaska during 1996. Purpose: The purpose of this project was to produce a 1:63,360-scale geologic map for the airborne geophysical surveys released by DGGS in the Chulitna region during 1996. The geologic data are important for identifying potential mineral deposits and for characterizing and distinguishing between geologic units.

Data were digitized from mylar compilations. Bedrock geologic information was compiled on stable mylar with abundant control points at 1:63,360 scale and registered in ArcEdit, then layered onto a 1:63,360-scale USGS topographic base. 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. Logical_Consistency_Report: Polygon topology present and clean on appropriate data; others are line or point data. Completeness_Report: This dataset includes geospatial information about geologic units, age and field sample locations, structural features, structural measurements, and dike locations. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data were determined visually using topographic maps at scales of 1:63,360 and larger. Altimeters were also used. Occasional use was made of hand-held GPS, but Selective Availability, a random 100-meter error assigned to GPS signals by the U.S. government, was in place at the time. Geologic contacts, sample, and station locations were visually hand-plotted onto stable mylar bases from the field maps. The coordinates of sample and station locations were entered into an Excel spreadsheet with a digitizing tablet. Station notes and sample descriptions were entered into an Excel spreadsheet. The lists of samples were visually checked against the lists of analyzed samples returned from the laboratories. It was verified that all the samples plotted on the maps are included in the various tables and spreadsheets. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 100 Horizontal_Positional_Accuracy_Explanation: Approximate error in meters. Considering the errors inherent in the USGS topographic maps, locating oneself in the field, the 100-meter random error of Selective Availability assigned to GPS signals, and the methods of digitizing localities, stations, and samples are located to an accuracy of between 10 and 100 meters.

See this publication cited in the Process Step section below Process_Step: Process_Description: Fieldwork - Fieldwork for bedrock investigations, including ridge and valley traverses, road cut investigations, and river exposures, was conducted for six weeks between June 1997 and July 1998 by a crew of from six to seven geologists. Field notes and rock samples were collected throughout the footprint of the geophysical survey for bedrock investigations. Approximately seven person-days were spent on field investigations for the surficial geology; most surficial geology was created from air photos. Bedrock mapping involved using the geophysical maps on a daily basis for checking geologic contacts and units. Mappers recorded observations in field notebooks and on topographic maps, predominantly at 1:63,360 scale. In some areas, photocopies of topography at varying enlarged scales were used. All compilations were made by hand on stable mylar at 1:63,360 scale. Stations were located using topographic maps, compasses, and altimeters. In some instances, GPS devices with location precision varying up to 100 meters were used. Stations were also plotted by hand on stable mylar topographic bases and coordinates determined with a digitizing tablet. Field notes were entered into an Excel spreadsheet in the field office. Source_Used_Citation_Abbreviation: Burns and others, 1997 Process_Date: 1998 Process_Step: Process_Description: Laboratory data compilation - Laboratory analyses were performed on rock samples collected during the fieldwork from June 1997 intermittently through December 1998. Published geochemical and age results are found in Clautice and others (2001) and Gage and others (1998). Unpublished laboratory results include petrographic work on thin sections and modal analysis of rock slabs stained for plagioclase and potassium feldspar. Results from major-oxide and trace-element geochemistry of igneous and metamorphic rocks were used to calculate CIPW Norms for use in classifying rocks according to established petrologic nomenclature. Thin sections produced by this study are currently stored at the DGGS office in Fairbanks, Alaska. Rock samples, including geochemical sample pulps and rock hand samples from most field stations, are currently stored at the DGGS warehouse in Fairbanks. Final storage for most rock samples generated by this study will be at the DGGS Geologic Materials Center (GMC) in Eagle River, Alaska.

Bedrock polygons were coded. Excel files of previously digitized point data, including age date samples, some major oxide analyses, dikes too small to plot at 1:63,360 scale, and structural measurements, were translated into Arc/Info format and plotted.
