Online_Linkage: http://dx.doi.org/10.14509/29661 Description: Abstract: Mineral Resources Section personnel from the Alaska Division of Geological & Geophysical Surveys (DGGS) carried out a geologic field survey, including mapping and sampling, in the eastern part of the Bonnifield mining district in the Fairbanks A-1 and A-2 and the Healy D-1 and D-2 quadrangles, Alaska, from June 16 through July 18, 2008. The fieldwork provides basic information critical to building an understanding of Alaska's geology and is part of an integrated program of airborne geophysical surveys followed by geologic mapping. Specifically, this work provides geologic context for geophysical surveys conducted in 2006. Interpretation and synthesis of this data has been presented in professional and trade meetings. This report and associated geologic map data are preliminary, have not undergone rigorous peer review, and will be superseded by a subsequent Report of Investigations map and report that will be issued later in 2016. The objective of the eastern Bonnifield project is to produce a 1:50,000-scale geologic map to foster a better understanding of the area's geology and mineral potential. Although DGGS concentrated on mapping the Paleozoic metamorphic rocks that host the volcanogenic massive sulfide deposits (VMS) and Mesozoic igneous rocks associated with Au-Ag-As-Sb veins, we also studied the Tertiary sedimentary section, which could contain coal resources. The geologic map data are available in digital format as ESRI shapefiles. Purpose: The objective of the eastern Bonnifield project is to produce a 1:50,000-scale geologic map to foster a better understanding of the area's geology and mineral potential. Although DGGS concentrated on mapping the Paleozoic metamorphic rocks that host the volcanogenic massive sulfide deposits (VMS) and Mesozoic igneous rocks associated with Au-Ag-As-Sb veins, we also studied the Tertiary sedimentary section, which could contain coal resources.

Logical_Consistency_Report: not applicable Completeness_Report: This report is intended to provide timely release of preliminary geologic interpretations. The report and accompanying digital dataset have been lightly reviewed for technical content. However, significant additional work is in progress to refine the geologic interpretations and ensure geospatial data integrity throughout the dataset. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Estimated position errors calculated by the hand-held GPS were a minimum of 3 m; at many locations the horizon was limited by steep topography, resulting in positional errors of more than 100 m. Lineage: Process_Step: Process_Description: Field data collection - Field traverses were planned and prioritized to cross important geophysical marker features, previously identified mineral occurrences, key outcrops, and sample sites from previous geologic investigations. Field observations were recorded in field notebooks and transcribed into a computer database in the field office and later completed in the DGGS offices. Location coordinates of observation sites were derived using hand-held Garmin GPS 12XL GPS units (no differential correction was applied). Estimated position errors calculated by the hand-held GPS were a minimum of 3 m; at some locations the horizon was limited by steep topography, resulting in positional errors of more than 100 m. Coordinates were downloaded to an MS Access database as UTM Zone 6 coordinates projected in NAD27 datum, and field observation site station identifiers were programmatically matched to the location. These matches were verified by field personnel. Field observation station locations are provided in this dataset as a point feature shapefile. Structural measurements of planar surfaces and lineation were collected from outcrops, sometimes multiple measurements were collected; in some cases where an outcrop trend or a trend of a lithology or fault could only be seen in two dimensions just the azimuthal trends were collected. Structural data was stored in the field database using the American right-hand rule (strike azimuth is 90 degrees counter-clockwise from the down-dip direction) for planar structures and as azimuth and plunge for lineation structures. Structural data were transcribed from geologists' field notes into an MS Access field database during the field season, and queried out of the database into the ESRI shapefile. Structural data are provided as a point feature shapefile in this dataset. The dataset includes all structural measurements that were collected and verified; not all measurements will be portrayed on the final map. Process_Date: 2008 Process_Step: Process_Description: Rock sample collection - Rock samples were collected for hand specimen, petrography, geochemistry, geochronology, coal quality, palynology, and fossil identification. Geochemical data have been released. Geochronological data have already been released. Palynological, coal quality, and sandstone data are in preparation. Process_Date: 2008 Process_Step: Process_Description: Map construction methods - Geologists recorded field observations and geologic interpretations on field maps; information on these field sheets, along with observations from field stations were compiled on a hand-drawn interpretive bedrock map in the field office. This compilation allowed the geologic team to collaboratively compile observations and interpretations and to aid in reaching a consensus among alternative interpretations. Once in the office this interpretive compilation was scanned and digitized. Final interpretation of geologic polygons, contacts, and geologic unit composition were completed in ArcGIS. Bedrock polygons have been edited to be topologically complete with no overlap, but have not received technical review. The current dataset does not include the identity, or identity and location confidence of contacts. Process_Date: 2008 Process_Step: Process_Description: Initial data release - Preliminary interpretations of bedrock unit extents and tabulated field observations of geologic structures were extracted from the in-progress geodatabase and released for public distribution.
