Geology of the Cretaceous Lascano-East intrusive complex : magmatic evolution and mineralization potential of the Merin Basin, Uruguay

Creator:: Cernuschi Rodilosso, Federico
Abstract:: The Cretaceous Merín aborted-rift basin of eastern Uruguay is composed of sub-alkaline Paraná-Etendeka province basaltic flows and shallow intrusives (~133 to 131 Ma), rhyolitic ignimbrites (~130 to 128 Ma) and associated mildly alkaline to alkaline intrusions and volcanic rocks (~128 to 127 Ma). Four intrusive complexes from 20 to >30...

Transboundary river floods : vulnerability of continents, international river basins and countries

Creator:: Bakker, Marloes H. N.
Abstract:: Floods are the most frequent and damaging of all types of natural disasters and annually affect the lives of millions all over the globe. However, researchers seem to have overlooked the fact that floods do not recognize national boundaries. Therefore, the phenomena of shared, or transboundary floods occurring in international...

Petrology and geochemistry of the Emigrant Pass volcanics, Nevada : implications for a magmatic-hydrothermal origin of the Carlin gold deposits

Creator:: Johnson, Curtis L.
Abstract:: The Emigrant Pass volcanics (EPV) are a 38.3 to 36.4 Ma calc-alkaline volcanic center that erupted andesite and dacite, and a late series of felsic dikes along the south flank of the Carlin gold district in north-central Nevada. The EPV includes dacite and rhyolite porphyry dikes indistinguishable from porphyry dikes...

Land trusts in the New West : conserving and responding to local geographies?

Creator:: Loynes, Kathryn
Abstract:: This research focuses on the relationship between the emerging role of land trusts and rapid growth and change in the West. Teton County, Idaho, Teton County, Wyoming, and Sublette County, Wyoming, and each of their associated land trusts, are used as case studies. Each county has experienced varying levels of...

Paleomagnetic inclination shallowing in deep-sea sediments

Creator:: Arason, Pórdur
Abstract:: In this thesis anomalous downcore shallowing of paleomagnetic inclinations is interpreted to be caused by sediment compaction. Thus, compaction-induced inclination shallowing may influence tectonic reconstructions that are based on inclinations from deep-sea sediment cores. Progressive downcore shallowing of the remanent inclination was observed in a 120-m section of Plio- Pleistocene...

Magma dynamics and evolution in continental arcs : insights from the Central Andes

Creator:: Grocke, Stephanie B.
Abstract:: Constraining the magma evolution and dynamics that lead to the eruption of large volume continental arc systems is fundamental to our understanding of continental crust formation. An investigation into the magmagenesis that results in the formation of the Central Volcanic Zone (CVZ) in the Andes of South America, situated atop...

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...

Transboundary groundwater : geopolitical consequences, commons sense, and the law of the hidden sea

Creator:: Jarvis, William Todd
Abstract:: With 97% of the world’s freshwater resources stored underground, the connection between groundwater resources to the metrics of space, scale and time common to the geographic study of natural resources has not been extensively investigated by geographers. While nearly 240 transboundary aquifers are mapped across the world, a potential “tragedy”...
