Neruokpuk Formation, northern Yukon : U-Pb detrital zircon and Ar-Ar sample descriptions, geochronology data tables and imagery / L.S. Lane, G.E. Gehrels, P.W. Layer. : M183-2/7733E-PDF

"The Neruokpuk Formation of northern Yukon and adjacent Alaska is a succession of Edicaran to Cambrian turbiditic sandstones, siltstones and shales comprising part of the northeastern Arctic Alaska terrane. Its provenance and original paleogeographic position with respect to NW Laurentia is a focus of study and debate. This report provides sample and site descriptions, field photos, thin section micrographs and images of zircon grain mounts for a suite of samples processed and analysed for detrital zircon U-Pb ages and detrital muscovite Ar-Ar ages. The complete filtered and sorted data tables for both the U-Pb and Ar-Ar results and U-Pb concordia plots are also presented here. These data document a provenance consistent with derivation from a NW Laurentian source area"--Abstract, page [3].
