The genesis of the San Vicente lead zinc rhythmite deposit, Peru : a petrologic, geochemical, and sulfur isotope study

Creator:: Schütfort, Erwin G.
Abstract:: The San Vicente zinc lead deposit is located in the Eastern Andes of Central Peru. The deposit is an epigenetic Mississippi Valley-type deposit based on stratigraphic, geologic, petrographic, and geochemical evidence. The dolomite host rocks of the Pucara Group are of Triassic-Jurassic age. The source of metals are red sandstones...

Sedimentary organic matter : distribution and alteration processes in the coastal upwelling region off Peru

Creator:: Reimers, Clare E.
Abstract:: Recent organic-rich deposits on the Peru continental margin occur along the upper slope (100-450 m) between about ll°S and 16°S and along the lower continental slope (>2000 m). The upper slope deposits reflect high biological production in response to coastal upwelling, but preservation of organic matter is enhanced by the...

Numerical response of concrete-lined tunnels crossing active faults

Creator:: Lange, Stephanie
Abstract:: A challenge for municipal authorities of growing urban areas is to provide larger and faster transportation and utility networks that are safe and resilient to significant disruptions after an earthquake event and other disasters. Urban regions, like the San Francisco Bay or the Los Angeles area, are situated in seismically...

Psychological Elements of Trauma and Grief among Young Banso Widows in Cameroon

Creator:: Lange, Ruth Kinyuy
Abstract:: Because of disease, industrialization, and regional conflicts, young widowhood is an expanding phenomenon in many parts of the world. Young widows face many challenges that can lead to mental health problems. The young widows have to make adjustments to fit their new roles as bread winners of the families, having...

Evaluating the Effects of Alleyway Management on the Performance of Dry-Farmed Pinot noir Grown in Different Soils

Creator:: Lange, Mathew
Abstract:: Vineyards in Oregon’s Willamette Valley are predominately planted to perennial grass cover in the alleyways of vineyards. This grass cover is grown to increase worker and equipment traction, as well as reduce erosion and manage vine vegetative vigor. However, with increasing frequencies of drought and warming temperatures, the use of...

Magmatic processes beneath mid-ocean ridges : insights from mineral and glass chemistry in plagioclase ultraphyric basalts

Creator:: Lange, Amy E.
Abstract:: Prior to eruption at mid-ocean ridges, melts must travel through >6 km of crust from their origin in the mantle. The final composition of the melts is dependent on both the melting conditions and magmatic processes within the crust. While mid-ocean ridge basalt (MORB) glasses are commonly used to infer...

Past Methane Release Events and Environmental Conditions at the Upper Continental Slope of the South China Sea: Constraints by Seep Carbonates

Creator:: Han, Xiqiu, Suess, Erwin, Liebetrau, Volker, Eisenhauer, Anton, and Huang, Yongyang
Abstract:: Authigenic carbonates and chemosymbiotic biota are archives of seepage 1 history and record paleo-environmental conditions at seep sites. Based on mineral and stable isotope compositions and U/Th-isotope systematics of seep carbonates and Calyptogena sp shell fragments from three seep sites located at 22°02' ~22°09'N, 118°43'~118°52'E (water depths: 473 m to...

Solvent Extraction Behavior of Mixed N, O-Donor Ligands for Separation of Trivalent f-Elements

Creator:: Karslyan, Yana
Abstract:: Nowadays selective separation processes are sought after more than ever before. They are indispensable to meet the growing demand for individual rare earth elements, minor actinides partitioned from fission-produced lanthanides, as well as, overall, more concentrated and high-purity products. This research focuses on such separation techniques as solvent extraction which...
