Advances In Seismic First-Arrival Tomography, David Paul Gaines

Doctoral Dissertations

Seismic first-arrival tomography is a technique currently experiencing a renaissance in popularity due to the simplicity of implementation and promising results for delineating a variety of subsurface targets. The purpose of this study is to investigate seismic first-arrival tomography in a variety of settings and applications, and thus to provide a solid framework for future work. The study largely consists of two separate themes, hydrogeophysics and low-velocity anomaly detection. Hydrogeophysics is an emerging field whereby measured geophysical properties are used as proxies for physical properties of the subsurface. This study represents one of the first high-resolution hydrogeophysical investigations in the …

Mesozoic Burial, Mesozoic And Cenozoic Exhumation Of The Funeral Mountains Core Complex, Death Valley, Southeastern California, Mengesha Assefa Beyene

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Funeral Mountains of Death Valley National Park, CA, provide an opportunity to date metamorphism resulting from crustal shortening and subsequent episodic extensional events in the Sevier hinterland. It was not clear whether crustal shortening and thus peak temperature metamorphism in the hinterland of the Sevier-Laramide orogenic wedge have occurred whether in Late Jurassic, Early Cretaceous , Late Cretaceous or somewhere between. Particularly ambiguous is the timing of crustal shortening in the deep levels of the hinterland of the Sevier belt, now manifest in the metamorphic core complexes, and how and when these middle-to-lower crustal rocks were exhumed. A 6-point …

Bedrock Geology Of The East Brookfield 7.5 Min. Quadrangle (Ebq), South-Central Massachusetts: Structural And Petrologic Evidence For The Nature Of Regional Deformation And Kinematics Of The Southern Central Maine Zone, Thomas Bradley Walker

Thomas Bradley Walker

Across-strike shortening from Maine to Connecticut is the most conspicuous orogen-scale feature of the New England Appalachians. Mapping (1:24000) and structural analysis in the EBQ and adjacent quads demonstrate that shortening in the southern Central Maine zone was accommodated by orogen-parallel elongation and orogen-normal flattening and thrusting. Map units are Rangeley Fm. (Sil-Bt-Grt schist and gneiss, Bt-Pl±Grt granofels; thin marble layers); Paxton Fm. (Bt-Pl±Grt granofels; calc-silicate granofels; Bt-Sil-Grt schist); tonalitic Bt orthogneiss (Bt-Pl-Qtz±Grt); migmatitic felsic and mafic gneisses and amphibolite; and leucopegmatites (10-m-scale thickness). Foliations (primarily compositional layering, leucosomes in the plane of flattening, Bt SPO, flattened quartz and feldspar …

Dissertations, Master's Theses and Master's Reports - Open

Remote sensing and advanced digital image processing techniques were developed and tested for delineating karst features important for the subterranean hydrology in the Tanamá River and Rio Grande de Arecibo catchments located in the North Coast Tertiary Basin of Puerto Rico, where groundwater contributes to base flow for surface water bodies which in itself is the main supply of drinking water. This aquifer region is a karst platform of carbonate rocks and clastic beds, thought to comprise a confined aquifer beneath and an unconfined aquifer. Products derived from ASTER, Landsat (ETM+ and TM), a NED DEM (30 m), and a …

Antarctic Plant And Phytoplankton Response To The First Phase Of The Mid Miocene Climatic Optimum At South Mcmurdo Sound, Lee Foersterling

LSU Master's Theses

The Antarctic Drilling Program (ANDRILL) recovered 1138.54 m of sub-seafloor marine sediments with 98% core recovery at the AND2-2A drill site in South McMurdo Sound. Biostratigraphy, magnetostratigraphy, and isotopic dating (Acton et al., 2008) indicated that an Early to Middle Miocene section (223-1138.54 mbsf) was recovered. This study focuses on an interval with high concentrations of palynomorphs, located between 460.57 and 403.48 mbsf and dated to 16.7 Ma to 16.2 Ma according to the updated Acton et al. (2008) ANDRILL SMS age model. Palynological results show a pronounced increase in organic microfossils between 434.01 and 431.91 mbsf, compared to levels …

Geochemistry, Geothermobarometry And Geochronology Of High-Pressure Granulites And Implications For The Exhumation History Of Ultrahigh-Pressure Terranes: Dulan, Western China, Benjamin David Joseph Christensen

All Master's Theses

The Dulan ultrahigh-pressure (UHP) rocks of the North Qaidam terrane, Western China, represent continental crust that has been subducted ~100 km during continental collision. Adjacent granulites representing burial to ~50 km could either be overprinted eclogites or a separate high-pressure-high-temperature (HP-HT) granulite unit. Overprinted eclogites and HP-HT granulites imply different P-T-t paths for UHP rocks. Metamorphic conditions for the granulites are 750–880 °C and 14–17 kbar. Zircon U-Pb geochronology, REE patterns and Ti-in-zircon thermometry indicate an increase in temperature from ~800 °C (449 Ma) to ~900 °C (418 Ma). This temperature increase could explain the presence of granulite leucosomes and …

Relationships Between Snake River Paleofloods, Occupational Patterns And Archaeological Preservation At Redbird Beach Archaeological Site In Lower Hells Canyon, Idaho, Tabitha Trosper

All Master's Theses

The Snake River basin drains 282,000 km² of the northwestern U.S. and is the largest tributary to the Columbia River. Redbird Beach, an archaeological site located in the lower Hells Canyon reach of the Snake River, contains extensive vertical exposures of archaeological materials interbedded with Snake River flood sediments. Redbird Beach formed in the lee of the Redbird Creek debris fan, is composed of interfingering deposits from large floods on the Snake River and locally-derived alluvial sediments from Redbird Creek. Through stratigraphic analyses of slackwater deposits, this study compares the temporal and spatial patterns of human occupation at Redbird …

Morphological Specification Of Chinianella Scheympflugi Hofmann, 1994, A Late Jurassic (?Earliest Cretaceous) Dasycladalean Alga Of The Western Tethyan Domain, Felix Schlagintweit

Studia UBB Geologia

The dasycladalean alga Chinianella? scheympflugi was described by Hofmann (1994) from the Tithonian of the Ernstbrunn Limestone of Lower Austria. This alga, so far unreported besides its type-locality, is reported from the Late Jurassic of Poland, the Northern Calcareous Alps of Austria, Crimea (Ukraine), and Greece (Parnassos Zone). Facies are well-agitated outer platform habitats (peri-reefal and back-reefal facies). The cylindrical thallus consists of three parts: a sterile Salpingoporella-like basal part (stalk), a fertile Chinianella-type main portion and a short sterile top part. The transition from the stalk to the main thallus portion is well marked and abrupt. The stratigraphic range …

New Data On Facies Development And Micropaleontology Of The Eastern Margin Of The Getic Carbonate Platform (South Carpathians, Romania): Case Study Of Mateiaş Limestone, Ioan I. Bucur, Daniela Beles, Emanoil Sasaran, Constantin Balica

Studia UBB Geologia

Mateiaş Limestone represents a lithostratigraphic unit included in the Braşov Series, which is a component of the eastern end of the Getic Nappes’ cover (the Getic carbonate platform). The study of the Mateiaş Limestone in Hulei-Mateiaş-Măgura area has evidenced three main facies, and five microfacies types. The Kimmeridgian (possibly also Early Tithonian) age of the Mateiaş Limestone has been assigned based on a microfossil association identified in thin sections. The regional framework, as well as their sedimentological and micropaleontological features point to the deposition of these limestones on shelf margin and slope environments; the succession in the studied area corresponds …

Late Jurassic–Early Cretaceous Foraminifera From Štramberk-Type Limestones, Polish Outer Carpathians, Daria Ivanova, Boguslaw Kolodziej

Studia UBB Geologia

Foraminifera studies were carried out on the Štramberk-type limestones which occur as pebbles to small boulders (exotics) within the uppermost Jurassic–Palaeogene flysch deposits of the Polish Outer Carpathians. The studies were focused on foraminifera from (1) reef and peri-reef facies, and (2) lagoonal algal-foraminiferal facies. The paper deals with 34 species (including 8 in open nomenclature) representing 30 genera, 22 families, 14 superfamilies, 11 suborders, and 7 orders. A more precise age determination has been obtained for 30 exotics, representing a Tithonian (mostly) to Valanginian age. Foraminiferal assemblages from at least two exotics suggest a Valanginian age as indicated by …

Classification And Fertility Of Soils In The Big South Fork National River And Recreation Area Based On Landscape Position And Geology, Ryan H. Blair

Masters Theses

The Big South Fork National River and Recreation Area encompasses more than 50,585 hectares (125,000 acres) of the Cumberland Plateau along the border of Tennessee and Kentucky. Highly dissected and steep terrain have made accessibility to much of the park limited, thus little work has been done to investigate the formation of these soils. Seven native soil profiles were selected for chemical and physical analysis representing Pennsylvanian-aged acidic sandstone and shale geology and landforms. The objectives of this study included the characterization of selected native profiles by physical and chemical analysis, as well as classification using US Soil Taxonomy, to …

Central New York Varve Chronology: A Suggestion For Quaternary Geologists, Thomas Bradley Walker

Thomas Bradley Walker

Work done to build a chronology of deglaciation using varves has been the focus of a number of researchers in New England for many years. The locations employed to build their timeline have been quite useful to date. However, New England is not the only place in the Northeast conducive to studying the last deglaciation of North America. The discovery of a set of ice proximal varves in an ancient glacial lake, now a swamp, in Oswego County, central New York, has shown that some locations outside of New England would be suitable for similar studies. The land having been …

Antarctic Climate Change And The Environment, Peter Convey, R. Bindschadler, G. Di Prisco, E. Fahrbach, J. Gutt, D. A. Hodgson, Paul Andrew Mayewski, C. P. Summerhayes, J. Turner, Acce Consortium

Earth Science Faculty Scholarship

The Antarctic climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system. We review these variations from the perspective of the geological and glaciological records and the recent historical period from which we have instrumental data (similar to the last 50 years). We consider their consequences for the biosphere, and show how the latest numerical models project changes into the future, taking into account human actions in the form of the release of greenhouse gases and chlorofluorocarbons into the atmosphere. In doing so, we provide an essential …
