On the Manifestation of Deformation and Evolution of Two Cenozoic Orogens

Creator:: Lamont, Ellen A.
Abstract:: The word orogenesis is derived from the Greek words oros meaning mountains and genesis meaning creation and refers to the study of the complex processes involved in the growth and evolution of mountain ranges (orogens). Orogens develop where crustal deformation builds topography and forms landscapes. This dissertation explores the role...

Quaternary Landscape Evolution and the Surface Expression of Plume-Lithosphere Interactions in the Greater Yellowstone Area

Creator:: Guerrero, Eduardo Francisco
Abstract:: Numerous investigations demonstrate that mantle convective processes such as upwelling affect the surface topography of the overriding plate. The surface expression of mantle flow has been coined ‘transient topography’. Transient topography in the North American plate is thought to result from a mantle thermal anomaly beneath the Yellowstone volcanic center,...

Spatio-Temporal Patterns of Tree Establishment in the M1 Meadow of the H.J. Andrews Experimental Forest

Creator:: Jones, Katherine E.
Abstract:: Montane meadows in the Cascade Range of Oregon have been declining due to tree establishment since records began. Montane meadow complexes in the H.J. Andrews Experimental Forest shrank by 60 to 75% from 1949 to 2005, but fine scale temporal and spatial processes of tree establishment in these meadows are...

Historical Change and the Hydrogeomorphic Context of Present-day Floodplain Forests in the Willamette Valley, Oregon

Creator:: Bervid, Heather D.
Abstract:: Floodplain forests play many important roles in the fluvial processes and environments of large alluvial rivers, including acting as geomorphological influences and habitat for native fish during high flows. Many large, gravel-bed river systems have undergone substantial change in recent centuries, resulting in loss of forested area to agriculture, reduction...

Structural geology of the Mount Polley Cu-Au district, south-central British Columbia

Creator:: Wafforn, Stephanie R.
Abstract:: The Mount Polley copper-gold deposit is one of a series of porphyry copper deposits that occur in a belt of accreted Mesozoic age island arc terranes in the Canadian Cordillera. The deposit comprises three breccia-hosted Cu-Au ore zones that are associated with a series of monzodiorite to monzonite intrusions emplaced...

North Pacific Humpback Whales (Megaptera Novaeangliae) in Northern Southeast Alaska: Population Trends, Monitoring, and Management

Creator:: Thurber, Rhianna L.
Abstract:: After the commercial exploitation of humpback whales (Megaptera Novaeangliae) ceased, population trends in the North Pacific increased with the implementation of federal protective legislation. The recovery of the population prompted the National Oceanic and Atmospheric Administration to divide the population into 14 Distinct Population Segments (DPSs) based on discrete geographic...

The Geology and Geochemistry of the Haquira East Porphyry Copper Deposit of Southern Peru : Insights on the Timing, Temperature and Lifespan of the Magmatic-hydrothermal Alteration and Mineralization

Creator:: Cernuschi Rodilosso, Federico
Abstract:: This dissertation is informally divided into three major sections. In the first section (Chapter 2) I use data from field mapping, isotopic geochronology, whole rock geochemistry and trace element concentrations in zircons to examine the petrology, geochemistry and ages of the Haquira East porphyry copper deposit of southern Peru. In...

Marine Low Clouds : Radiation, Turbulence, and Forecasting

Creator:: Verlinden, Kathryn L.
Abstract:: High-resolution ship-based observations of a nearly uniform stratocumulus deck in the southeast Pacific during 17 days of the 2008 VOCALS regional experiment elucidate radiation and turbulence in the marine boundary layer (MBL). A new method for prescribing observations-based cloud properties to the Rapid Radiative Transfer Model is presented and applied...

The 3.1 Ma to 100 ka Goat Rocks Volcanic Complex: Persistence and Evolution of Magmatism at a Long-Lived Major Andesite Locus on the Cascade Arc

Creator:: Wall, Kellie T.
Abstract:: The imposing andesite stratovolcano is the characteristic expression of subduction zone magmatism, posing hazards to coastal populations and bearing insight into deep Earth processes. On a map of a typical volcanic arc, one can easily distinguish the approximately linear alignment and regular spacing of these major edifices that stand out...

The Deschutes Formation: evidence of extension-enhanced explosivity in the early High Cascades

Creator:: Pitcher, Bradley W.
Abstract:: The eruptive history of the Quaternary Cascades arc has been relatively well characterized. However, much less is known about the frequency and sizes of explosive eruptions produced by earlier stages of the arc. The Late Neogene Deschutes Formation of Central Oregon preserves a remarkable record of heightened pyroclastic activity during...
