| Description: | Research Report Abstract: Numerous bentonite clays interbedded with shale and coal are exposed in the interfingering, Cretaceous sediments along the Colville River and its tributaries in northern Alaska. Two bentonite beds of high purity, ten to twelve inches thick, are conveniently accessible at Umiat Mountain, four miles northeast of Umiat, Alaska. X-ray diffraction, X-ray fluorescence and other diagnostic techniques revealed the bentonite to be nearly pure montmorillonite with certain beidellitic characteristics. It is proposed that this clay be known as Umiat bentonite. (Authors' abstract) |
