Mid-Miocene magmatic system development in the northwestern United States by Matthew E Brueseke( )

1 edition published in 2006 in English and held by 2 WorldCat member libraries worldwide

This dissertation investigates the spatial, temporal, geochemical, and petrologic development and evolution of mid-Miocene volcanic systems in the southeastern Oregon Plateau region of Oregon and Nevada. This integrated field and laboratory investigation conclusively demonstrates that flood basalt volcanism occurred on the Oregon Plateau over at least a 2 m.y. duration, and provides the first comprehensive view into the development of a mid-Miocene Oregon Plateau volcanic field and its relationship with regional flood basalt volcanism. The first portion of this study focuses on the geochemical and chronostratigraphic characteristics of flood basalt lava flows in the vicinity of Steens Mountain, Oregon. New 40Ar/39Ar ages and recalculated literature ages from the Steens Basalt type section illustrate that multiple magmatic centers were present locally, and that Oregon Plateau flood basalt activity was coeval with the main phase of Columbia River Basalt Group volcanism. The remainder of this study focuses on the Santa Rosa-Calico volcanic field (SC) of northern Nevada in order to better define and understand the link between mid-Miocene Oregon Plateau mafic and silicic volcanism. In the SC, mafic through silicic eruptive loci and shallow intrusive bodies are exposed along broadly north-south trending alignments, coincident with regional lithospheric structures. At least sixteen physically and compositionally distinct units are exposed in the SC representing approximately 2 m.y. of magma production. Local mafic volcanism was dominated by the eruption of Steens Basalt magmas. SC silicic magmas were produced by basaltic magma induced crustal melting of granitoid upper crust and erupted from diverse vent types and locations. At least four distinct intermediate (andesite-dacite) magmatic systems also are documented. Physical, chemical, and isotopic data indicate that open-system petrogenetic processes played a substantial role in the generation of these magmas and also influenced the chemical characteristics of SC mafic and silicic units. The complex array of physical and chemical characteristics and processes displayed and documented by SC units provide an exceptional example of how compositionally diverse volcanic fields develop. Moreover, these complexities establish an important link between regional mid-Miocene mafic magma production and the generation of silicic-dominated volcanic fields on the Oregon Plateau

Geomicrobial processes and diversity in ultra-high pressure metamorphic rocks and deep fluids from Chinese Continental Scientific Deep Drilling by Gengxin Zhang( )

1 edition published in 2006 in English and held by 1 WorldCat member library worldwide

This dissertation investigates the microbial communities and microbe-mineral interactions in ultra-high pressure metamorphic rocks and deep fluids from the Chinese Continental Scientific Drilling (CCSD) project by using geochemical, mineralogical, cultivation and molecular microbiology methods. The drilling site is located in the eastern part of the Dabie-Sulu ultra high-pressure metamorphic (UHPM) orogenic belt at the convergent plate boundary between the Sino-Korean and Yangtze Plates. This integrated approach conclusively demonstrates that microbes can survive in the deep continental subsurface (down to 3350 m) and they play important roles in mineral transformations and elemental cycling. The first half of this study focuses on geochemical conditions and diversity and metabolic functions of microbial community. Characterization of SSU rRNA genes indicated that the bacterial clone sequences shifted form a Proteobacteria-dominated community to a Firmicutes-dominated one with increased depth. From the ground surface to 2030 m, most clone sequences were related to nitrate reducers, with a saline, alkaline, and cold habitat. From 2290 to 3350 m most sequences were closely related to anaerobic, thermophilic, halophilic or alkaliphilic bacteria. The archaeal diversity was low. Most archaeal sequences from the ground surface to 3350m were not related to known cultivated species, but to environmental clone sequences recovered from subsurface marine environments. An important contribution of this research is an enrichment of a thermophilic (optimal temperature of 68oC) organism from 2450m with an ability to reduce Fe(III) and oxidize Fe(II) under different conditions. This enriched organism was capable of reducing Fe(III) in aqueous form and in the structure of clay minerals and iron oxides at acidic pH. This organism was also capable of oxidizing Fe(II) in aqueous form and in the structure of pyrite and siderite. The second half of this dissertation focuses on microbe-mineral interactions by using enriched and isolated cultures to react with clay and iron oxide minerals. Mesophilic and thermophilic iron-reducing bacteria were incubated with lactate as the electron donor and structural Fe(III) in solid minerals as the sole electron acceptor. Extensive mineral reaction took place. One important such reaction was the smectite to illite reaction promoted by mesophilic and thermophilic metal reducing bacteria. This particular reaction highlights the significant role of iron-reducing bacteria in promoting the smectite to illite reaction at high temperature
Seafloor spreading processes in protoarc-forearc settings : eastern Albanian ophiolite as a case study by Charity M Phillips( )

1 edition published in 2004 in English and held by 1 WorldCat member library worldwide

Northern Albania's Mirdita ophiolite displays two distinct belts of Jurassic Neotethyan oceanic crust that developed between the Apulian and Pelagonian margins. The western belt consists of an ~3-km-thick MORB pseudostratigraphy, in which pillow lavas overlie serpentinized peridotites, suggesting tectonic extension dominated early stages of seafloor spreading. The eastern belt includes an ~10-km-thick complete pseudostratigraphy with extrusives that show increasing IAT chemistry upsection. Mutually intrusive relations between crustal units indicate robust magmatic spreading occurred. Four dike generations (D1-D4) exist based on structure, crosscutting relations, and texture. D1-D4 are composed of diabase dikes. D1 strike 030-060°, dips SE, and is crosscut by NE dipping D2 dikes oriented 290-340°. D3-D4 crosscut D1-D2 and strike of 240-290° with northerly dips. Boninite and rhyodacite dikes intruded throughout the SDC's history because of complex magmatic processes. These relations suggest the spreading direction changed from NNE-SSW to NW-SE because of the incipient Mirdita-Pelagonia collision in the South
The tectonomagmatic evolution of the late cenozoic Owyhee Plateau, northwestern United States by Kurt A Shoemaker( )

1 edition published in 2004 in English and held by 1 WorldCat member library worldwide

The Owyhee Plateau (OWP) is an intermontane basalt plateau located at the nexus of the Snake River Plain (SRP) and Oregon Plateau/High Lava Plains (OP/HLP) volcanic provinces, which has been the locus of nearly continuous basaltic magmatism since 17 Ma. Between 17-11 Ma, generally evolved basaltic lavas related to the Steens flood basalt event and Oregon-Idaho Graben (OIG) volcanism were erupted around the extending margins of the OWP. Beginning 11 Ma, less differentiated olivine tholeiites were erupted throughout the OWP proper, from low shield vents with alignments consistent with regional stress fields. After 5 Ma, volcanism retreated to the margins of the OWP, ultimately becoming limited to the northern transition region between the OWP and the OIG. The youngest basalts in the OWP region are <0.25 Ma mildly alkaline basalts erupted in this transition region. The OWP is the only location in the northwestern US where basalt types characteristic of the OP/HLP (high-alumina olivine tholeiite, HAOT) and the SRP (SRP-type olivine tholeiite, SROT) occur together in significant quantity, in close spatial and temporal association, and with a full spectrum of compositions intermediate between the two. Sr, Nd, and Pb isotopic characteristics are decoupled from bulk chemistry, and reflect time-dependent variations in contributions from different lithospheric and sublithospheric mantle reservoirs. I propose that the OWP is a discrete tectonomagmatic entity within the North American Cordillera resulting from Sevier-style thrusting of accreted lithosphere over a westward-projecting shelf of Precambrian cratonic lithospheric mantle. Low-angle subduction during Laramide time trapped a layer of asthenospheric mantle below the OWP region, which was subsequently modified by fluids and melts from the subducting Farallon slab. Foundering of the Farallon slab caused upwelling of hot, fertile asthenosphere that mixed with this volatile-enriched layer, triggering Steens volcanism. Subsequent melt production from fluid- and melt-metasomatized cratonic and accreted mantle reservoirs beneath the OWP produced the post-11 Ma HAOT-SROT association. The retreat of volcanism to the margins of the OWP, the isotopic character of these lavas, and the absence of endmember SROT on the OWP after 5 Ma reflect the exhaustion of fusible components from the Precambrian lithospheric mantle shelf
Formation of precursor calcium phosphate phases during crystal growth of apatite and their role on the sequestration of heavy metals and radionuclides by Olaf J Borkiewicz( )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

Due to increasing risk associated with the contamination of the environment with heavy metals and radionuclides, societies worldwide are facing a pressing need for new more efficient environmental remediation techniques. One approach that gained considerable attention over the last two decades is in situ metal stabilization by phosphate amendments - a technique based on the coprecipitation of contaminant species with phosphates and the formation of insoluble metal(M)-substituted minerals, such as apatite Ca5-xMx(PO4)6(OH, Cl, F). One of the major results of this dissertation is that formation of apatite at Earth-surface conditions is preceded by crystallization of other less stable calcium phosphates (precursors) that ultimately transform to apatite. The first part of this dissertation investigates formation and evolution of calcium phosphate precursors under conditions simulating those found in Earth-surface environments. The pathways of phase development in the Ca(OH)2-H3PO4-H2O system were studied using conventional ex situ as well as in situ time-resolved X-ray diffraction. The results clearly indicate formation of precursors under conditions found at the Earth-surface, which may be relevant not only in the context of natural soil environments, but also in the context of engineered conditions, like those found during metal stabilization by phosphate amendments. In the second part of the dissertation, pathways of calcium phosphate development in the presence of different metal ions (Zn, Cd, Sr, U, and Th) are studied by time-resolved X-ray diffraction. The results clearly indicate a significant influence of contaminant species on the pathways of phase development in the Ca(OH)2-H3PO4-H2O system. Secondary metal-bearing phases, far more soluble than hydroxylapatite, were often formed in the presence of the metals studied. Finally, the role of precursor formation on the heavy metal sequestration and fate during crystal growth of apatite was studied by a combination of powder X-ray diffraction, SEM/EDS and ICP-AES. The results indicate significant reduction in the solution concentration of metals during formation of precursor phases and relative stability of the contaminant species during structural transformation of phases involved in low-temperature crystallization of hydroxylapatite. Fluctuations in the concentration of elements observed during structural changes in the system suggest a dissolution-recrystallization mechanism of transformation of amorphous phases to brushite and parascholzite
Geomicrobiological studies of saline lakes on the Tibetan Plateau, NW China : linking geological and microbial processes by Jiang Hong Chen( )

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

Lakes constitute an important part of the global ecosystem as habitats in these environments play an important role in biogeochemical cycles of life-essential elements. The cycles of carbon, nitrogen and sulfur in these ecosystems are intimately linked to global phenomena such as climate change. Microorganisms are at the base of the food chain in these environments and drive the cycling of carbon and nitrogen in water columns and the sediments. Despite many studies on microbial ecology of lake ecosystems, significant gaps exist in our knowledge of how microbial and geological processes interact with each other. In this dissertation, I have studied the ecology and biogeochemistry of lakes on the Tibetan Plateau, NW China. The Tibetan lakes are pristine and stable with multiple environmental gradients (among which are salinity, pH, and ammonia concentration). These characteristics allow an assessment of mutual interactions of microorganisms and geochemical conditions in these lakes. Two lakes were chosen for this project: Lake Chaka and Qinghai Lake. These two lakes have contrasting salinity and pH: slightly saline (12 g/L) and alkaline (9.3) for Qinghai Lake and hypersaline (325 g/L) but neutral pH (7.4) for Chaka Lake. We have taken an integrated approach combining geochemistry, molecular phylogeny (both DNA and RNA based, both 16S rRNA and amoA gene), quantitative PCR (total Bacteria, Archaea, total crenarchaeota, AOA, and AOB), and cultivation and isolation. Both lake water and sediments have been analyzed. The results are divided into four chapters and they are summarized below. In addition, I also studied microbial communities and functions in sediments from South China Sea, a potential site for gas hydrate deposits. This work was done as extra add-on to the microbial ecology studies in Titeban lakes
Characterization of the physical, chemical, and biological factors that control the fate and transport of bacteria through glacial-outwash sediments by Beth Louise Mitchell( )

1 edition published in 2006 in English and held by 1 WorldCat member library worldwide

This study investigated the effects of sediment grain size distribution, mineralogy and surface charge, and bacterial surface charge on bacterial transport through natural porous media. Bacterial flow-through experiments were conducted using three intact heterogeneous sediment cores. Sediments were characterized for their physical and chemical properties. The surface charge of the suspended bacteria in the influent and effluent was also measured. Results indicated that the presence of dolomite was significant to the fractions of retained bacteria. Surface charge of the effluent bacteria results indicated that the attractive forces between the sediments and bacteria were significant to bacterial transport. The overall results of this study indicate that degree of sorting, presence of carbonates, and surface charge of the bacteria are all related to the number of retained bacteria
Sequence stratigraphy of the Curtis, Summerville and Stump formations, Utah and northwest Colorado by William Thomas Wilcox( )

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

The Jurassic Curtis, Summerville and Stump formations of Utah and Colorado consist of marine and marginal-marine strata deposited along the southern margin of the Western Interior Seaway. Although previous investigations have documented the distribution, lithologic characteristics, and environments of these units, they have been difficult to correlate regionally due to internal lithofacies variations and the lack of age-diagnostic fossils. In this study I present new data consisting of 34 biostratigraphic samples and 25 measured stratigraphic sections demonstrating the stratigraphic equivalency of the Curtis and Summerville formations with the Stump Formation and demonstrate that deposition occurred between early and late Oxfordian time (~161-155 Ma). Detailed sedimentological field data allows formulation of a sequence-stratigraphic model that indicates these formations were deposited during a single transgressive-regressive sequence. The new sequence stratigraphic model helps clarify the stratigraphic architecture of the Middle-Upper Jurassic rocks of the region and may serve as a guide for interpretations of other tidally-influenced depositional systems
Reservoir characterization of the mid-Cretaceous Dakota Formation, southern Uinta basin, Utah by Joshua Peter Dark( )

1 edition published in 2008 in English and held by 1 WorldCat member library worldwide

In the southern Uinta Basin of eastern Utah, fluvial channel sandstones of the Albian-Cenomanian Dakota Formation are economic gas reservoirs. Recovery of gas from the Dakota Formation has proven challenging due to local variability in reservoir sandstone thickness, distribution, and quality. To evaluate the physical characteristics of potential reservoir sandstones, I have constructed two photomosaics of Dakota Formation fluvial channel complexes, measured 13 vertical sections with accompanying outcrop gamma-ray logs, and recorded 1,100 paleocurrent orientations along approximately 40 kilometers of outcrop exposure. Outcrop data were compared with subsurface geophysical/petrophysical and production data to evaluate possible ties between channel sandstone attributes and hydrocarbon occurrence. The primary controls of economic gas accumulation within the Dakota Formation are structure and channel sandstone distribution. Secondary controls include diagenesis and lithology. Amalgamated channels in the lower portions of the Dakota Formation have the greatest potential for economic gas production
Microbial reduction of Fe(III) in multiple clay minerals by Shewanella putrefaciens and reactivity of bioreduced clay minerals toward Tc(VII) immobilization by Michael Bishop( )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

The reactivity of clay minerals toward technetium immobilization utilizing a suite of clay minerals ranging from smectite-illite including montmorillonite, nontronite, rectorite, mixed layered I-S (70:30), and illite, with chlorite (ripidolite), and palygorskite common in nature. The clay minerals were characterized utilizing multiple techniques. Fe-Oxides were removed prior to bioreduction using a modified dithionite-citrate-bicarbonate method. Fe (II) in the bioreduced clay minerals is used to reduce Tc(VII) to Tc (IV) in PIPES buffer. In the S:I series, the smectite end member was most effective in reducing Tc (VII) and the illite member the least effective, parallel to the extent and rate of Fe(III) bioreduction of these minerals. For all the clay minerals, the ratio of oxidized Fe(II) to reduced Tc(VII) was ~3.5±0.5. These kinetic results are important for our understanding of how various clay minerals may be used to immobilize heavy metal Tc at DOE contaminated sites
Spatial and temporal patterns of non-volcanic tremor along the southern Cascadia subduction zone by Devin C Boyarko( )

1 edition published in 2009 in English and held by 1 WorldCat member library worldwide

Episodic tremor and slip (ETS), the spatial and temporal correlation of slow slip events (SSE) monitored via GPS surface displacements and non-volcanic tremor (NVT) monitored via seismic signals, is a newly discovered mode of deformation thought to be occurring down-dip from the seismogenic zone along several subduction zone megathrusts. We investigate in detail eight NVT episodes between 2005 and 2007 with source locations extending over a 650 km along-strike region from northern California to northern Oregon. The initiation and termination points of laterally-continuous tremor activity appear to be repeatable features between NVT episodes which support the hypothesis of segmentation within the ETS zone. We find as much as 50 km spatial offset from the up-dip edge of the tremor source zone to the down-dip edge of the thermally- and geodetically-defined transition zones. NVT activity is also spatially anticorrelated with local seismicity, suggesting the two processes occur exclusive of one another
