Tungsten Mineralization

K–Ar dating of magmatic biotite, and of hydrothermal biotite and muscovite, demonstrates that quartz monzonite intrusion and exoskarn scheelite mineralization at Cantung, N.W.T., took place over a brief interval in the Upper Cretaceous (ca. 91 Ma). The regional age relationships of magmatic and ore-forming activity in the Logan–Mackenzie Mountains are poorly defined, but it is tentatively inferred that tungsten mineralization may have been related to a late stage in the plutonic development of the area.

Banks Island

A marine teleostean assemblage, from within 2 m of the base of the Upper Cretaceous Kanguk Formation on Banks Island, is dominated by scales of Osmeroides? transversus and Ichthyodectes ctenodon, as well as bones of a primitive teleost tentatively referred to the salmoniforms. The fish indicate a shallow, calm paleoenvironment. Possible mechanisms of deposition include aerobic flotation decay, scale loss by living fish, and deposition of carnivore feces. The assemblage indicates a Cenomanian or Turonian age for the basal Kanguk, with an Early Turonian age preferred by correlation with the late Early Turonian fishes of Lac des Bois, Northwest Territories.
