Double subduction beneath Hispaniola? an investigation of earthquakes by body wave inversion

Creator:: Ludwig, Rainer
Abstract:: High seismic activity occurs along the Caribbean and the North American Plate boundary beneath the eastern part of Hispaniola. A large number of intermediate to deep earthquakes are clustered between the Puerto Rico Trench to the north and the Muertos Trench to the south suggesting the possibility of concurrent subduction...

Chile trench : extensional rupture of oceanic crust and the influence of tectonics on sediment distribution

Creator:: Schweller, W. J. (William John)
Abstract:: Extensive new trackline coverage of the Chile Trench between 23°S and 34°S, including more than 60 bathymetric and seismic reflection profiles across the trench axis, allows a much more detailed study of the tectonics and sedimentation of this feature than previously possible. Sediment distribution along the axis shows a remarkable...

A field and geochemical study of the boundary between the Nanga Parbat-Haramosh massif and the Ladakh arc terrane, northern Pakistan

Creator:: Verplanck, Philip L.
Abstract:: The Nanga Parbat-Haramosh massif (NPHM) is a north-south trending structural and topographic high, which interrupts the east-west trend of the Himalaya in northern Pakistan. Previously, the massif was thought to be bounded by the Main Mantle thrust (MMT), a north-dipping thrust along which the Kohistan-Ladakh arc was thrust south over...

The mechanics of the Salt Range-Potwar Plateau, Pakistan : qualitative and quantitative aspects of a fold-and-thrust belt underlain by evaporites

Creator:: Juame, Steven C.
Abstract:: The collision of the Indian subcontinent with Asia beginning 40 million years ago produced the Himalayan orogenic belt, the largest continental collision belt active today. The foreland fold-and-thrust belt in northern Pakistan consists of the Salt Range-Potwar Plateau area. In this region the distance from the Main Boundary Thrust(MBT) to...

Subsurface densities & lithospheric flexure of the Himalayan foreland in Pakistan, interpreted from gravity data

Creator:: Duroy, Yannick
Abstract:: Gravity data along a N-S profile from Kohistan to the Punjab plain of Pakistan have been incorporated into recent interpretation of the gross structure of the foreland fold and thrust belt of the Himalaya. In northern Pakistan large deviations from Airy Isostatic equilibrium are observed. An excess of mass characterizes...

Structure and shortening of the Kangra and Dehra Dun reentrants, Sub-Himalaya, India

Creator:: Powers, Peter M.
Abstract:: Surface-geology, oil-well, seismic-reflection, and magnetostratigraphic data are integrated to evaluate structural style and shortening rate at the Himalayan front (Sub-Himalaya) of northwest India. The Sub-Himalaya, between the Main Boundary thrust and the Himalayan Frontal fault, is the actively deforming front of the Himalaya. At certain locations, the Himalayan Frontal fault...

The Ore Bin ; Vol. 38 No. 6 (June 1976)

Creator:: Oregon. Dept. of Geology and Mineral Industries, Allen, John Eliot, 1908-, and Beaulieu, John D.
Abstract:: The geology of Oregon has become a jigsaw puzzle of moving parts set on a foundation of changing conditions as the crust and mantle undergo successively different manners of deformation through time. As more megahypotheses arise from increasingly sophisticated views of plate tectonics and from more detailed analyses of synoptic...

The Ore bin ; Vol. 34 No. 8 (August 1972)

Creator:: Oregon. Dept. of Geology and Mineral Industries and Beaulieu, John D.
Abstract:: 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....

Changes in gravity anomalies during erosion and isostatic rebound of collisional mountain ranges

Creator:: Enos, Robert A.
Abstract:: At collisional mountain ranges the tectonic history of crustal shortening and subsequent post-collisional erosion is preserved in the form of the presently observed gravity anomalies. In this study, models of erosion and isostatic rebound at various stages of collision illustrate the evolution of crustal structure, topography, and resulting gravity anomalies....
