Thrust Faulting along the Lower Rogue River, Klamath Mountains, Oregon
The Dothan Formation, a thick sandstone unit of the northern Klamath Mountains in Oregon, is of undetermined age owing to its lack of fossils and uncertain stratigraphic position. The Galice Formation, a more argillaceous unit of Oxfordian and Kimmeridgian age, is underlain with apparent conformity by the volcanic Rogue Formation. The Dothan Formation is also underlain by a similar volcanic unit. The writer proposes that the Dothan and Galice Formations are contemporaneous facies deposited in different parts of the basin and that they and the underlying Rogue Formation have been placed in juxtaposition by thrusting from the southeast.
