Publication_Date: 2014 Edition: 1.1 Series_Information: Series_Name: Scientific Investigations Map Issue_Identification: 3291 Publication_Information: Publication_Place: Denver, Colorado Publisher: U.S. Geological Survey Description: Abstract: This map was developed by the U.S. Geological Survey Mineral Resources Program to depict the fundamental geologic features for the western part of the Fortymile mining district of east-central Alaska, and to delineate the location of known bedrock mineral prospects and their relationship to rock types and structural features. This geospatial map database presents a 1:63,360-scale geologic map for the Kechumstuk fault zone and surrounding area, which lies 55 km northwest of Chicken, Alaska. The Kechumstuk fault zone is a northeast-trending zone of faults that transects the crystalline basement rocks of the Yukon-Tanana Upland of the western part of the Fortymile mining district. The crystalline basement rocks include Paleozoic metasedimentary and metaigneous rocks as well as granitoid intrusions of Triassic, Jurassic, and Cretaceous age. The geologic units represented by polygons in this dataset are based on new geologic mapping and geochronological data, coupled with an interpretation of regional and new geophysical data collected by the Alaska Department of Natural Resources, Division of Geological and Geophysical Surveys. The geochronological data are reported in the accompanying geologic map text and represent new U-Pb dates on zircons collected from the igneous and metaigneous units within the map area. Purpose: The purpose of this map developed by the US Geological Survey Mineral Resources Program is to depict the fundamental geologic features for the western part of the Fortymile Mining District of east-central Alaska and to delineate the location of known bedrock mineral prospects and their relationship to rock types and structural features such as faults. The geospatial data in this file include polygons of geologic units, geologic contacts (known, inferred, and concealed), faults (known, inferred, and concealed) for normal, thrust, strike slip, and those with undetermined sense of offset direction. As well, the traces of anticline and synclines, which are interpreted in the metasedimentary rocks southwest of Mount Veta. Expanded unit descriptions are presented in associated documentation.

Each line segment has a length and directionality that is appropriate for the geologic feature it depicts. The map was reviewed by USGS staff for consistency with basic geologic principles and general conformity to USGS mapping standards. Completeness_Report: Data provided in the database represent the first 1:63,360 geologic mapping of the study area. These data are considered complete and the highest resolution data presently available. Attribute_Accuracy: Attribute_Accuracy_Report: The Attribute values in each database layer were assigned by the map authors. Attribute fields and values were reviewed and checked for accuracy and consistency of terms. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Most of the geologic features in this database are considered to be accurately located and within +/- 10 meters of their actual location on the 1:63,360-scale topographic base maps. Accuracy of the geologic features diminishes in areas that are poorly exposed and vegetated. The 1:63,360 topographic maps and corresponding Digital Raster Graphics (DRGs) used as the primary mapping base for this project were assumed to meet the National Map Accuracy Standard of +/- 32 meters. Points data obtained from GPS devices have an accuracy of +/- 3 meters Lineage: Process_Step: Process_Description: Geologic mapping and data capture was completed during summer field investigations conducted 2008-2010. Resulting field maps were scanned, georegistered, and digitized using ArcGIS 10. Prospect, observation, and rock sample locations, digitally recorded with hand-held GPS devices, were imported into ArcGIS to produce the point features in this data set. Rock ages were determined by Sensitive High Resolution Ion Microprobe (SHRIMP) analysis at USGS laboratories in Stanford, CA. Geospatial layers were attributed appropriately, and features were symbolized to produce digital maps.
