The area is part of the Circle mining district and adjacent to the Fairbanks mining district. This report includes detailed geologic, 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. The investigation of gold, 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 map has been compiled and drawn under contract between the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys, and WGM, Mining and Geological Consultants, Inc. Airborne geophysical data for the area was acquired by Dighem Surveys & Processing, Inc. in 1993. completed State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys GIS Data Manager/Cartographer (907) 451-5029 (907) 451-5020 (907) 451-5050 3354 College Road Fairbanks AK 99709-3707 USA dggspubs@alaska.gov You may view our web site at http://www.dggs.alaska.gov for the latest information on available data.Please e-mail your questions and data requests when possible since our web site and e-mail address will remain current even if our phone number and mailing address change. pointOfContact notPlanned Aereal Aerial Photography Aeromagnetic Survey Age Dates Alluvial Deposits Alluvium Amphibolite Ar-Ar Bedrock Bibliography C14 Carbonates Clastics Coal Colluvial Deposits Colluvium Conductivity Survey Conodonts Electromagnetic Survey Fan Faulting Faults Fluvial Folding Fossils Geologic Geomorphology Glacial Glacial Deposits Glacial Drift Granite Hornfels Hornblende Igneous Rocks K-Ar Magnetite Major Oxides Metamorphic Grade Metamorphic Minerals Metamorphism Mineralogy Modal Analysis Petrography Plutonic Plutonic Hosted Porphyry Precious Metals Quartz Regional Regional Metamorphism Sample Location Sandstone Schist Sedimentary Structure Surficial Tectonics Terranes theme None Alaska, State of Birch Creek Circle Hot Springs Circle Mining District Circle Quadrangle Crooked Creek Mammoth Creek Mastodon Dome place None Tintina Fault Yukon-Tanana Terrane Yukon-Tanana Upland stratum None Cretaceous Holocene Paleozoic Pleistocene Quaternary Tertiary temporal None The State of Alaska makes no express or implied warranties (including warranties of merchantability and fitness) with respect to the character, function, or capabilities of the electronic services or products or their appropriateness for any user's purposes.

Altimeters were also used. GPS technology was not used to determine locations. Instead, 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 determined with a digitizing tablet. All samples plotted on the maps are included in the various tables. Horizontal Positional Accuracy The estimated horizontal error of this dataset is +/- 100 meters. Considering the errors inherent in the USGS topographic maps, locating oneself in the field, and the digitizing method, all localities, stations, and samples are located to an accuracy of between 10 and 100 meters. meters 100 This dataset includes geospatial information about geologic units, sample locations for radiometric age dates, structural features and structural measurements. Many of the lithologic and anaylitical samples collected for this project are housed at the Alaska Geologic Materials Center (GMC). This dataset includes geospatial information about geologic units, sample locations for radiometric age dates, structural features and structural measurements. Many of the lithologic and anaylitical samples collected for this project are housed at the Alaska Geologic Materials Center (GMC). The logical consistency of the polygon, point and line files has been visually checked but not systematically verified. Some topology errors are known to exist in the polygon files. This lineage was generated by the FGDC CSDGM to 19139 transformation The geologic data included in this project were digitized from a mylar compilation of geologic field maps produced on USGS topo bases of the area. Map unit (polygon) locations and attributes were checked by two reviewers broadly familiar with the dominant geologic rock types in the Fairbanks area. Locations were determined visually using topographic maps at scales of 1:63,360 and 1:25,000.Geologic contacts, sample, and station locations were visually hand-plotted onto stable mylar bases from the field maps. 1995-01-01T00:00:00 This project was included in a legacy data rescue effort.
