The project took place during two periods: a reconnaissance mapping effort June 12-22, 2017, and a detailed campaign from June 18 to July 16, 2018. This map is located within an area of current industry interest; it includes the Taurus porphyry copper-gold-molybdenum +/- rhenium deposit and several other occurrence types, including gold, copper, and molybdenum in porphyritic intrusions, structurally controlled silver-lead-zinc prospects, and placer gold deposits. This map includes unconsolidated surficial deposits in the Tanacross D-1 Quadrangle, the eastern one-third of the Tanacross D-2 Quadrangle, the northern half of the Tanacross B-2 Quadrangle and the northeastern one-third of the Tanacross B-2 Quadrangle. Surficial geology was primarily mapped by interpreting 2.5-m-resolution SPOT 5 color-infrared and natural color red-green-blue (RGB) imagery collected in 2009 and 2010 and stereoscopic pairs of approximately 1:65,000-scale, false-color, infrared aerial photographs taken in 1978 and 1981. Surficial mapping was augmented with helicopter-supported fieldwork June 20-23, 2017 and July 3-4, 2018 to visit exposures and check geologic mapping. The complete report and digital data are available from the DGGS website: http://doi.org/10.14509/30197. Purpose: This map is located within an area of current industry interest; it includes the Taurus porphyry copper-gold-molybdenum +/- rhenium deposit and several other occurrence types, including gold, copper, and molybdenum in porphyritic intrusions, structurally controlled silver-lead-zinc prospects, and placer gold deposits. The northeastern Tanacross Quadrangle is characterized by a very complex geologic history and prior to DGGS work in the area, the most-detailed mapping was at 1:250,000 scale. DGGS mapping will provide detailed geologic context for the known porphyry systems in the map area and links to mineral occurrences elsewhere in the region, including structural detail linking the porphyries to mineral occurrences in western Yukon, Canada. Supplemental_Information: This digital data distribution package provides a geodatabase that portrays features presented in PIR 2019-6.

Lineage: Process_Step: Process_Description: Bedrock mapping - The Mineral Resources section of the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted 500 mi2 of 1:63,360-scale geologic mapping in the northeastern Tanacross Quadrangle (Tanacross D-1, and parts of the C-1, C-2, and D-2 quadrangles), located 15 miles southeast of Chicken, Alaska. The project took place during two periods: a reconnaissance mapping effort June 12-22, 2017, and a detailed campaign from June 18 to July 16, 2018. To create this map we incorporated (1) geologic information from previous geologic mapping and published literature, (2) new interpretations using remotely sensed imagery, and (3) information gathered from limited field investigations. A complete list of references is available in the accompanying report. Process_Date: 2018 Process_Step: Process_Description: Surficial geology - Surficial geology was mapped by interpreting 2.5-m-resolution SPOT 5 color-infrared and natural color red-green-blue (RGB) imagery collected in 2009 and 2010 and stereoscopic pairs of approximately 1:65,000-scale, false-color, infrared aerial photographs taken in 1978 and 1981. SPOT 5 imagery was interpreted in ArcGIS Pro by overlaying it on hillshade and slopeshade images derived from Interferometric Synthetic Aperture Radar (IFSAR) bare-earth digital-elevation models (DEMs) created using data collected in 2010. By using the pseudo-3-D functionality of ArcGIS Pro and adjusting the transparency of the SPOT 5 imagery and the transparency and color of hillshade and slopeshade images, we were able to visualize subtle differences in features and identify geologic landforms. We used aerial photographs to identify geologic features and check our interpretations. Geospatial polygon features, representing geologic units, were drawn using onscreen digitizing techniques in ArcGIS Pro. We conducted helicopter-supported fieldwork June 20-23, 2017 and July 3-4, 2018. During fieldwork we visited exposures and dug soil pits to examine material and gather information for unit descriptions and check geologic mapping. We also measured the thickness of the active layer at several locations. Process_Date: 2018 Process_Step: Process_Description: GIS analysis and digital cartography - The geologic and geographic features portrayed in this data distribution package were attributed according to the GeMS (Geologic Map Schema) geodatabase standard. https://ngmdb.usgs.gov/Info/standards/GeMS/ Process_Date: 2019 Process_Step: Process_Description: Technical review - This is a final report of scientific research. It has received technical review and editing by several scientists familiar with the subject matter. We incorporated the reviewers' suggestions into the final draft when deemed appropriate.
