Detailed facies analysis is presented for the Nanushuk Formation in outcrop in the central North Slope. Facies associations are interpreted and described. Simplified measured sections are presented along with detailed segments of measured sections to illustrate facies and facies association stacking patterns.

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).

The State of Alaska Division of Geological & Geophysical Surveys (DGGS) and Division of Oil & Gas (DOG) are currently engaged in a multi-year study of the hydrocarbon potential of the Tertiary and Mesozoic strata in Cook Inlet basin. Modal analyses and routine core analyses were performed on Tertiary and Mesozoic siltstones and sandstones collected during the 2007-2010 field seasons from six geographic areas in upper and lower Cook Inlet. The reservoir quality of Cook Inlet sandstones varies widely depending on their mineralogy, geologic age, burial depth, and depositional environment. Tuxedni and Naknek sandstones have poor reservoir quality and are likely to be of equally poor quality down dip. West Foreland sandstones...

This Raw Data File provides lithologic descriptions of core fragments recovered from a series of core holes drilled by Exxon (mid-80s) in the uplands bordering the Yukon Flats basin. In addition to descriptions of the material, the tabulated file includes geographic location, core hole numbers, an age estimate, core fragment depth, general lithology, grain size, and facies interpretation. The author examined these core materials in Fairbanks during winter and spring 2002. This work was done in preparation for an assessment carried out by the U.S. Geological Survey of undiscovered, technically recoverable hydrocarbon resources in the Yukon Flats basin.
