Styx River geologic mapping

Project Details

Project ID:
1228
Nickname/Abbreviation:
Styx
Parent Project:
Alaska strategic and critical minerals assessment
Status:
Complete
Description:
Geologic mapping in the Styx River area of the Lime Hills C-1 Quadrangle. The Mineral Resources Section conducted four weeks of fieldwork during summer 2013, as part of the state-funded Airborne Geophysical/Geological Mineral Inventory (AGGMI) Program. This work included refining contacts, subdividing major map units, and identifying new dikes and faults. The resulting 1:63,360-scale geologic map and supporting geochemical, petrologic, and geochronologic data fosters better understanding of the geology and mineral potential of the area. This project was funded through the Strategic and Critical Minerals Assessment capital improvement project, a component of the ongoing AGGMI Program funded by the Alaska State Legislature and managed by DGGS.
