Alaska Division of Geological & Geophysical Surveys (DGGS) has conducted 1:63,360-scale geologic mapping of the Sagavanirktok B-1 Quadrangle (640 square km�equivalent to four 7.5 minute quadrangles). This mapping project reinterprets micropaleontologic correlations for 17 Sagavanirktok Quadrangle wells, and reprocesses data from the one publicly-available seismic line. Surface geologic mapping, subsurface-to-surface stratigraphic age control, and seismic framework are required to reliably decipher the complex geology of this key area of the Brooks Range. Outcrops within the Sagavanirktok B-1 Quadrangle are the closest surface expressions of Prudhoe Bay source and reservoir rocks. This study yields critical petroleum-related...

The 1:63,360 Kavik River geologic map area consists of ~620 square miles and ties together previous DGGS mapping in the Sadlerochit and Shublik Mountains area of the western Arctic National Wildlife Refuge (ANWR) on the east and the structurally complex foothills and mountain front near the Kemik gas accumulation on the west. The map area exposes a unique intersection of North Slope stratigraphy where all three major depositional megasequences are mappable in close association (Ellesmerian, Beaufortian, and Brookian).

During 2004 and 2005 DGGS Energy Section geologists, together with University of Alaska Fairbanks and USGS personnel, conducted 1:63,360-scale geologic mapping in the Siksikpuk River Area of the Chandler Lake B-4 and C-4 quadrangles in northern Alaska. This work was conducted as part of the USGS-funded STATEMAP project, part of the National Cooperative Geologic Mapping Program.

Alaska Division of Geological & Geophysical Surveys (DGGS) has conducted 1:63,360-scale geologic mapping of the Sagavanirktok B-1 Quadrangle (640 square km�equivalent to four 7.5 minute quadrangles). This geologic map was produced by merging a bedrock geologic map and a surficial geologic map of the Eagle A-2 Quadrangle. This mapping project reinterprets micropaleontologic correlations for 17 Sagavanirktok Quadrangle wells, and reprocesses data from the one publicly-available seismic line. Surface geologic mapping, subsurface-to-surface stratigraphic age control, and seismic framework are required to reliably decipher the complex geology of this key area of the Brooks Range.
