Abstract
The Artinskian to Kungurian Sequence of the Otto Fiord area is dominated by the Great Bear Cape, Raanes and Trappers Cove formations in addition to the upper portions of the Nansen and Hare Fiord formations. The Great Bear Cape Formation (10-300 m), in the Otto Fiord area, is a yellowish-weathering, cliff-forming, packstone to grainstone dominated by echinoderms, bryozoans, and brachiopods. The Raanes Formation (10-225 m) is greenish-weathering, recessive to resistant, shaly to silty, variably cherty wackestone to packstone dominated by bryozoans, brachiopods, crinoids, and sponge spicules in addition to resistant, massive, very fine-grained, bryozoan-lime mud wackestone forming bioherms. The Trappers Cove Formation (55-1000 m) is black to dark gray spiculitic chert that is interfingered with thinly-bedded, black, recessive shales and siltstones. (Abstract shortened by UMI.)
