The field area for the Taylor Mountain project is within a 50-mile radius of Chicken, Alaska. The project area is of current and historic interest for potential mineral resource development, including quartz vein Au mineralization, placer Au deposits, granite-hosted tin mineralization, and intrusion-related Cu-Au deposits. Prospects in the area include Tweeden, Liliwig, and others. Much of the field area was mapped at 1:250,000 scale by the USGS in the 1960s. This project aims to produce more accurate and modern geologic maps and supporting datasets that will promote mineral resource exploration in eastern Interior Alaska. All files are available from the DGGS website: http://doi.org/10.14509/30837. Purpose: The Taylor Mountain project is a component of the Earth Mapping Resources Initiative (Earth MRI; formerly known as 3DEEP), which is a partnership between the U.S. Geological Survey (USGS), the Association of American State Geologists (AASG), and other Federal, State, and private-sector organizations. The goal of the effort is to improve our knowledge of the geologic framework in the United States and to identify areas that have the potential to contain undiscovered critical mineral resources. Enhancement of our domestic mineral supply will decrease our reliance on foreign sources of minerals that are fundamental to the Nation's security and economy.

Field observations and rock descriptions in this data file have not been reviewed for technical content and should be considered preliminary. As the project commences, further observations, geochemical data, microscopic investigation, or other information may provide additional insights into sample and station lithology or features. Magnetic susceptibility measurements were collected using Terraplus KT-10 model handheld magnetic susceptibility meters. The KT-10 meters have a maximum sensitivity of 1 x 10^-6 SI units on smooth surfaces and a measurable susceptibility range between 0.001 x 10^-3 and 1999.99 x 10^-3 SI.

Revised descriptions may become available in the future through new publications, DGGS web services, or division databases. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data for field stations were collected using GPS-enabled tablets or smartphones running the ESRI Field Maps App. Data were merged into an ArcGIS geodatabase. The devices have a reported error between 10-12 m. Latitude and longitude are reported in the WGS84 datum. Lineage: Process_Step: Process_Description: Field data collection - Location data for field stations were collected using GPS-enabled tablets or smartphones running the ESRI Collector App. Rock descriptions are composed of observations and interpretations made by project geologists in the field or in the field office. Station descriptions were lightly edited for clarity, but they have not been reviewed for technical content and should be considered preliminary. Magnetic susceptibility measurements were collected using Terraplus KT-10 model handheld magnetic susceptibility meters. The values reported here are for individual measurements performed on representative surfaces of the sampled rock outcrop.
