Publication_Date: 2023 Title: Field station locations and magnetic susceptibility data for the Chena-Pogo and Mount Harper projects, Big Delta and Circle quadrangles, Alaska, collected June-September 2023 Geospatial_Data_Presentation_Form: csv Series_Information: Series_Name: Raw Data File Issue_Identification: RDF 2023-27 Publication_Information: Publication_Place: Fairbanks, Alaska, United States Publisher: Alaska Division of Geological & Geophysical Surveys Other_Citation_Details: 3 p Online_Linkage: https://doi.org/10.14509/31096 Description: Abstract: Field station locations and magnetic susceptibility data for the Chena-Pogo and Mount Harper projects, Big Delta and Circle quadrangles, Alaska, collected June-September 2023, Raw Data File 2023-27, provides field station locations and magnetic susceptibility data for the Chena-Pogo and Mount Harper projects, Big Delta and Circle quadrangles, Alaska, collected June-September 2023, Raw Data File 2023-27, provides locations, field descriptions of rocks, and magnetic susceptibility measurements from rock outcrop and/or hand samples from the Mount Harper and the Chena-Pogo project areas. The field area for the Mount Harper project is north of Delta Junction and northeast of the Alaska Highway and extends southeast to 40-50 miles northwest of Tok. The Chena-Pogo project area is 0-200 miles south and east of Chena Hot Springs. During the 2023 field season, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted 1:100,000-scale bedrock geologic mapping of ~5,700 mi2 (~15,000 km2) within the Big Delta and Circle quadrangles, Alaska. The project areas are of current and historical interest for potential mineral resource development, including quartz vein gold (Au) systems, placer Au deposits, granite-hosted tin mineralization, and intrusion-related copper (Cu)-Au deposits. The Chena-Pogo and Mount Harper areas include the Pogo lode gold mine and the Healy, Lucky 13, Eagle, and many other prospects. The DGGS Mount Harper and Chena-Pogo projects aim to produce more accurate and integrated modern geologic maps and supporting datasets to promote mineral resource exploration in eastern Interior Alaska. These data are available from the DGGS website: http://doi.org/10.14509/31096. Purpose: The purpose of the Mount Harper and Pogo projects is to produce more accurate, detailed, and modern geologic maps and supporting datasets that will promote mineral resource exploration in eastern Interior Alaska. The project areas are of current and historical interest for potential mineral resource development, including quartz vein gold (Au) systems, placer Au deposits, granite-hosted tin mineralization, and intrusion-related copper (Cu)-Au deposits.

Logical_Consistency_Report: Not applicable Completeness_Report: This data releaase is complete. 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 reported errors between 10 and 12 m. Latitude and longitude are reported in the WGS84 datum. Locations were converted to NAD83 coordinates to provide consistency with adjacent data. Lineage: Process_Step: Process_Description: Field rock descriptions - During the 2023 field season, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted 1:100,000-scale bedrock geologic mapping of ~5,700 mi2 (~15,000 km2) within the Big Delta and Circle quadrangles, Alaska. Field rock descriptions are observations and interpretations made by project geologists in the field. Process_Date: 2023 Process_Step: Process_Description: Magnetic susceptibility measurements - 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 Système International (S.I.) units on smooth surfaces and a measurable susceptibility range between 0.001 x 10-3 and 1,999.99 x 10-3 S.I. The values reported here are for individual measurements performed on representative surfaces of the sampled rock outcrop and/or hand samples. Up to 12 susceptibility readings were recorded at each field station. We measured multiple sides of outcrops and/or hand samples to avoid atmospheric effects whenever possible. Magnetic susceptibility was not measured at a small portion of field stations because hand samples were intensely weathered or not large enough to cover the coil of the KT-10 meter for accurate measurement. These stations are presented with zero measurements for completeness.
