Chapter 6: Geotechnical and Seismic
STUDY AUTHORS: Knight Piésold, Water Management Consultants / Schlumberger Water Services, Frontier Geosciences, Inc., USGS
Based on site geotechnical investigations and previous literature, this chapter discusses aspects of surficial geology, overburden and bedrock geology, hydrogeology, physiography, topography, and surficial materials in their relation to rock mass characterization, movement of water through these materials, and seismicity. Regional volcanism and active fault systems also are addressed.
- The western end of the northeast-southwest trending Lake Clark-Castle Mountain Fault system is located east of the mine study area at the end of Lake Clark. The Lake Clark Fault is considered inactive by the United States Geological Survey.
