Detterman, R.L., 1956, New and redefined nomenclature of Nanushuk group, IN Gryc, George, and others, Mesozoic sequence in Colville River region, northern Alaska: American Association of Petroleum Geologists Bulletin, v. 40, no. 2, p. 233-244. [Available online, with subscription, from AAPG archives: http://www.aapg.org/datasystems or http://search.datapages.com]


Summary:

Named as marine formation in Nanushuk group. Rocks were formerly lower part of Topagoruk member of Umiat formation. Type locality designated as exposures on left bank of Anaktuvuk River where river breaches Grandstand anticline, 68 deg 56'N, 151 deg 10'W, also location of measured type section, 1700 ft thick. Basal part is predominantly fine-grained light olive-gray to dark-yellow-red sandstone with thin greenish "salt-and-pepper" sandstone and subordinate amounts of siltstone and shale. In upper part, siltstone and silt shale constitute about 50% of unit; minor amounts of coal is in sequence. Unconformably overlies Tuktu formation; underlies and intertongues with Killik tongue (new) of Chandler formation (all of Nanushuk group). Contains fossils. Age shown on chart as Early and Late(?) Cretaceous.
