  Citation × Citation Citation Abstract Copy Title: The Ore bin ; Vol. 34 No. 8 (August 1972) Author: Beaulieu, John D., Oregon. Dept. of Geology and Mineral Industries The plate tectonic history of Oregon is but one piece of a worldwide jigsaw puzzle encompassing much of geologic time. With the splitting of Pangaea in Mesozoic times, Oregon has occupied the leading edge of the North American Plate as it has impinged upon the ancestral oceanic East Pacific Plate. In the process Oregon has undergone profound subduction type tectonism. In addition, it may have acquired much lithospheric material from other plates, possibly some of the Paleozoic rocks of the Klamaths from Asia, ultramafic rocks and volcanic rocks from the Triassic oceanic crust, and the Siletz River Volcanics from the Eocene deep-sea floor. In middle Tertiary times, Oregon, along with the rest of western North America, actually caught up with the East Pacific Rise, an event which profoundly altered the pattern of tectonic behavior within the state. Flood basalts and block faulting replaced andesitic volcanism and thrust faulting as the dominant mode of tectonism. The pattern of deformation in late Tertiary times is extremely complex and a plate tectonic model consistent with all the data has yet to be formulated.

  Citation × Citation Citation Abstract Copy Title: The Ore bin ; Vol. 33 No. 4 (April 1971) Author: Lowell, Robert P., Couch, Richard W., Oregon. Dept. of Geology and Mineral Industries Seismically active areas exist within Oregon. The seismic history of Oregon is too short to be used as an accurate predictor of earthquake size, number, and distribution. Continual monitoring of earthquakes by seismograph stations during the next several decades should provide a more accurate estimate of the seismicity of Oregon. To provide adequate and accurate coverage additional seismograph stations are needed, particularly in southeastern Oregon. Rapid urbanization of the Willamette Valley and extensive public works planned for other areas of Oregon make it imperative that the stabilities of the areas be known. Specialized equipment such as portable microearthquake seismometer arrays, which have been developed to assist in local immediate problems, can accurately map active fault zones. In addition, they can locate active zones of continuing deformation which exist without producing the larger release of elastic strain energy of felt earthquakes. Studies of both historical and concurrent seismicity of an area should be of paramount importance when considering potential sites for nuclear generating stations or large construction projects such as dams, airports, large office buildings, and housing developments.
