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 Cenozoic Holitna basin is a gravity-defined feature that sits astride the Denali-Farewell fault zone in southwestern Alaska. The basin corresponds to a gravity low in excess of -40 milligals (mGals). No outcrops exist within the footprint of the gravity low and no subsurface data are available; consequently, the stratigraphy and age of its fill are unknown. The Alaska Division of Geological & Geophysical Surveys (DGGS) investigated the shallow gas potential of the basin during the summers of 2000 and 2002 by studying Tertiary coal-bearing rocks exposed along the Denali-Farewell fault zone to the northeast of the basin in the southern McGrath Quadrangle as an outcrop analog to the subsurface stratigraphy of the...
