Basaltic volcanism and tectonics of the High Lava Plains, southeastern Oregon

Creator:: Jordan, Brennan T.
Abstract:: The High Lava Plains province (HLP) of southeastern Oregon is a Miocene to Recent volcanic upland characterized by widespread basaltic volcanism and west-migrating rhyolitic volcanism. New ⁴⁰Ar/³⁹Ar ages for HLP rhyolites demonstrate that the trend of migrating rhyolitic volcanism is robust, reflecting westward migration at a rate of -35 km/m.y....

Crustal structure of the Queen Charlotte Transform Fault Zone from multichannel seismic reflection and gravity data

Creator:: Scheidhauer, Maren
Abstract:: The Queen Charlotte Fault system is a segment of the North America - Pacific plate boundary. From 45 Ma - 5 Ma, plate motion has been primarily translational. Since 5 Ma, transpression has been the dominant mode of interaction. The plate boundary west of the Queen Charlotte Islands is characterized...

Convergent margin magmatism in the central Andes and its near antipodes in western Indonesia : spatiotemporal and geochemical considerations

Creator:: Salisbury, Morgan J.
Abstract:: This dissertation combines volcanological research of three convergent continental margins. Chapters 1 and 5 are general introductions and conclusions, respectively. Chapter 2 examines the spatiotemporal development of the Altiplano-Puna volcanic complex in the Lípez region of southwest Bolivia, a locus of a major Neogene ignimbrite flare- up, yet the least...

P and S velocity structure beneath the Gulf of Maine

Creator:: Sattel, Daniel
Abstract:: Seismic refraction data collected in 1985 by the USGS were used in this study to derive the P and S velocity structure of the crust beneath the Gulf of Maine. The data quality differs among instruments and is affected by surficial lateral heterogeneities, a ringy source signature and reverberations. Velocity...

Stratigraphy, sedimentology, and eruptive dynamics of the 2-ka eruption of Misti Volcano, southern Peru

Creator:: Harpel, Christopher J.
Abstract:: The 2-ka eruption of Misti volcano produced voluminous flowage deposits and a wide-spread tephra-fall deposit. The flowage deposits form large terraces within channels draining the south side of the volcano. All the channels drain into the city of Arequipa. Arequipa's city center is ~16 km from the summit of the...

Seismotectonics of the explorer region and of the Blanco Transform Fault Zone

Creator:: Braunmiller, Jochen
Abstract:: In this thesis, we present the first detailed, long-term seismotectonic studies of oceanic ridge-transform systems. The proximity of the Juan de Fuca plate to a network of broadband seismic stations in western North America provides a unique synergy of interesting tectonic targets, high seismicity, and recording capabilities. Our main tools...

Thin-skinned tectonics on continent/ocean transitional crust, Sulaiman Range, Pakistan

Creator:: Jadoon, Ishtiaq Ahmad Khan
Abstract:: Surface and subsurface data from the Sulaiman thrust belt show that nearly all the 10 km thick sequence of dominantly platform (>7 km) and molasse strata is detached at the deformation front. These strata thicken tectonically to a minimum of 20 km in the hinterland of the Sulaiman fold belt...

Active tectonics of the Kashmir Himalaya (NW India) and earthquake potential on folds, out-of-sequence thrusts, and duplexes

Creator:: Gavillot, Yann G.
Abstract:: Active tectonics of a deformation front constrains the kinematic evolution and structural interaction between the fold-thrust belt and the most-recently accreted foreland basin. At the Himalayan deformation front, the thrust front is blind, characterized by a broad fold (the Suruin-Mastgarh anticline (SMA)), and displays no emergent faults cutting the southern...

Structure of the crust beneath Lake Superior from forward modeling of large aperture seismic data

Creator:: Shay, John T.
Abstract:: Both travel times and amplitudes of large offset refracted and reflected arrivals observed during GLIMPCE (Great Lakes International Multidisciplinary Program on Crustal Evolution) along line A in Lake Superior have been modeled using two-dimensional ray tracing techniques. Forward modeling was used to iteratively refine an initial velocity model that was...

The termination of the Basin and Range Province into a clockwise rotating region of transtension and volcanism, central Oregon

Creator:: Trench, David
Abstract:: Normal faults characterizing extensional provinces may terminate along-strike at regions of zero extension, at zones of transform faults, or at triple junctions. Termination of the Basin and Range extensional province in southeastern Oregon is thought to occur by right-lateral transform motion distributed across the Brothers Fault zone (BFZ) in central...
