| Summary: | Bibliography: p. 311-329. ... : Siliciclastic strata between Carmacks and Dawson in west-central Yukon were previously interpreted as Eocene or younger in age and fluvial/continental in origin. Detailed stratigraphic and sedimentologic investigations in the Indian River and Sixtyrnile River areas indicate that some of the strata are much older and were deposited in a paralic environment. The Indian River Formation (new) is at least 500 m thick and consists of interbedded sandstone, shale, conglomerate dinoflagellates and minor indicate coal. that the Spores, formation pollen and is Middle Albian in age and was deposited in a hitherto unrecognized marginal marine basin by a southward prograding fan-delta complex. The Sixtyrnile Formation (new) is approximately 200 m thick and consists of interbedded conglomerate, sandstone, shale and minor limestone and tuff, and intercalated basalt flows. the close association of Palynomorphs, fossil leaves and volcanic rocks indicate the formation is Late Cretaceous-Paleocene in age, possibly ... |
