Paleomagnetic study of some Cretaceous and Tertiary sedimentary rocks of the Klamath Mountains province, California Paleomagnetic study of some Cretaceous and Tertiary sedimentary rocks of the Klamath Mountains province, California
Paleomagnetic investigation of Cretaceous outliers and Tertiary sedimentary strata of the Klamath Mountains province, and of onlapping Cretaceous strata, has shown the rocks to be largely remagnetized. Samples studied are from the Upper Jurassic to Upper Cretaceous Great Valley sequence, Upper Cretaceous Hornbrook Formation, Eocene Montgomery Creek Formation, and Oligocene(?) Weaverville...

Paleomagnetic data from the Coso Range, California and current status of the Cobb Mountain normal geomagnetic polarity event Paleomagnetic data from the Coso Range, California and current status of the Cobb Mountain normal geomagnetic polarity event
Two basalt flows which erupted about 1.08 m.y. ago in the Coso Range, California, have normal magnetic polarity and thus provide additional evidence for the Cobb Mountain normal polarity event. A review of available data confirms that this event was of geomagnetic origin. A mean age of 1.10 ± 0.02 m.y. B.P. for the Cobb Mountain normal polarity event was found to best fit all available...

Post 12 m.y. rotation of southwest Washington Post 12 m.y. rotation of southwest Washington
Paleomagnetic field directions from the basalt of Pack Sack Lookout are compared to those from the Pomona Member of the Saddle Mountains Basalt of the Columbia River Basalt Group. The Pomona crops out over a wide region on the Columbia Plateau east of the Cascade Range, and the basalt of Pack Sack Lookout crops out well to the west of the Cascades about 30 to 60 km east of the Washington...

A geologic reconnaissance of the Cycladic blueschist belt, Greece A geologic reconnaissance of the Cycladic blueschist belt, Greece
The Cycladic blueschist belt consists of two distinctive segments separated by a broad zone of superposed granitic and high-temperature metamorphic rocks. The northern segment contains early metamorphic fold axes and parallel glaucophane lineations that trend ∼060° with a progressive increase in metamorphism toward the southeast. The southern segment contains similar fold axes and...
