Volcanology and petrology of the Rattlesnake Ash-Flow Tuff, eastern Oregon

Creator:

Streck, Martin J.

Abstract:

The Rattlesnake Ash-Flow Tuff erupted 7.05±0.01 Ma from the western Harney Basin, southeastern Oregon. The location of the vent area is inferred based on vent-ward increases in size of pumices, in degree of welding, and in degree of post-emplacement crystallization. Today's outcrops cover 9000 km2 and estimated original outcrop coverage...

Three-dimensional gravity analysis of the Pacific-Antarctic east Pacific rise at 36.5°S, 49.8°S and 54.2°S

Creator:

Enriquez, Kelly D.

Abstract:

Three-dimensional gravity analysis is the process of removing the predictable components from the free-air gravity anomalies and has proven to be useful for interpreting the subsurface structures and active processes at mid-ocean ridges. The three-dimensional effects of the seafloor and Moho topography, assuming a constant crustal thickness and constant crust...

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...

Dissertation
The oligocene and miocene geology of the Tillamook embayment Tillamook County, northwest Oregon

Creator:

Parker, Michael J. (Michael John), 1958-

Abstract:

Eleven sedimentary and volcanic rock units are mapped and described in the thesis area, and chronicle the dynamic geologic history of the Tillamook embayment from the Oligocene through the middle Mlocene. The oldest unit is the Zemorrian to early Saucesian Smuggler Cove formation, a bathyal tuffaceous mudstone with some thin-...

The geochemistry and geochronology of the Eocene Absaroka volcanic province northern Wyoming and southwest Montana, USA

Creator:

Hiza, Margaret M.

Abstract:

The Absaroka volcanic province is the largest of Eocene volcanic fields in the northern Cordillera of the western U.S., and consists of 25,000 km2 of lava flows, shallow intrusions, ash-flow tuffs and volcaniclastic deposits. It is aligned with northwest-trending Precambrian lineaments, and includes the remains of at least ten volcanic...

The Calvin impact crater, Cass County, Michigan : identification and analysis of a subsurface ordovician astrobleme

Creator:

Milstein, Randall L.

Abstract:

The Calvin impact crater is an isolated, nearly circular subsurface structure of Late Ordovician age in southwestern Michigan. The crater is defined by 110 on and gas test wells, has a rim to rim diameter of 6.2 km, an overall dimensional diameter of 8.5 km and consists of a central...

The 1988 Lancang-Gengma, China, earthquake sequence : teleseismic body wave, surface wave and strong ground motion studies

Creator:

Li, Xiao-qing, 1963-

Abstract:

On November 6, 1988, two strong earthquakes (Mw: 7.0 and 6.8) separated by about 13 minutes occurred in Yunnan Province, China. The aftershocks located by Kunming Telemetered Seismic Network form a lineament approximately 120 km long and 20 km wide with the long dimension oriented approximately N30°W. The epicenter of...
