Klamath-Blue Mountain lineament, Oregon
Abstract
Regional gravity data clearly show a zone of southwest-northeast lineations across Oregon that defines a major crustal lineament. Its existence is supported by geologic and geophysical data. Its correlation with the northwestern boundaries of the Klamath and Blue Mountain provinces suggests that these are continuous beneath the Cascade volcanic arc. The lineament may represent a pre-Tertiary strike-slip continental margin which, from paleomagnetic evidence, later rotated clockwise into its present position. *Present address: Earth Physics Branch, Department of Energy, Mines and Resources, Ottawa, Ontario, Canada K1A 0Y3
