Geology Of The Oquirrh Mountains, Utah, United States Geological Survey

All U.S. Government Documents (Utah Regional Depository)

The Oquirrh Mountains are located in north-central Utah, immediately south of the Great Salt Lake, in the easternmost part of the Basin and Range physiographic province. The range consists of northerly-trending aligned peaks 56 kilometers long flanked on the west by Tooele and Rush Valleys and on the east by Jordan and Cedar Valleys. The range hosts several of the more prominent base- and precious-metal and desseminated-gold mining areas in the western United States. The 130-year old Bingham porphyry copper mining district, which is of world-class magnitude in the central part of the range, is still active. The Mercur mining …

Geology Of The Dereiçi (Şavsat, Artvin) Cu-Pb-Zn Deposits, Mesut Soylu, Ayhan Erler

Turkish Journal of Earth Sciences

The geological relationships between the rock units in the Dereiçi/Şavsat (Artvin) region and vein-type Cu-Pb-Zn deposits were presented in this paper. The study area comprises the Upper Cretaceous intermediate volcanic rocks and sedimentary rocks, with Post-Eocene dykes of andesitic and diabasic composition. The mineral deposits are classified as (1) Sphalerite-Galena-Chalcopyrite-Pyrite veins (Talatin Madeni, Binektasi and Fikrinin Madeni), (2) milky quartz-Chalcopyrite-Sphalerite-Galena-Pyrite veins and (3) Chalcopyrite-Pyrite veins. The general paragenetic sequence of the mineralizations is observed as quartz I-pyrite-chalcopyrite-sphalerite-galena-quartz II-chalcocite-covellite. The wall rocks are subjected to silicification, sericitic alteration, chloritization and carbonatization.

Recognition And Analysis Of Secondary Depositional Crusts In The Surficial Aquifer System Of Southeast Florida, Steven Louis Krupa

Electronic Theses and Dissertations 1990 - 1999

This investigation identified, analyzed, characterized and correlated observed geophysical log "deflections" occurring at distinct depths in the sedimentary sequence and varying systematically with reference to the coastline. The deflections correspond to dense, hard crusts within the upper portions of the Surficial Aquifer System (SAS) of Southeast Florida. These crusts are proposed as zones of paleo-freshwater fluctuations within the aquifer. The secondary depositional crusts (SDC) have migrated vertically in response to sea level changes over thousands of years. Detailed continuous geological samples were collected from three boreholes in a contamination investigation in Delray Beach, Florida. These disturbed but representative samples were …

Late Pleistocene Glacial Chronology Of The Western Ahklun Mountains, Southwestern Alaska, Jason P. Briner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

New glacial mapping and 35 cosmogenic ³⁶Cl surface exposure ages, the first ever reported from Alaska, constrain the extent and timing of late Pleistocene glacial fluctuations in the western Ahklun Mountains, southwestern Alaska. Morphometric and soil relative-age data characterize two main drift units deposited during the Arolik Lake and Klak Creek glaciations, named herein. During the Arolik Lake glaciation (early Wisconsin), outlet glaciers emanated from an ice cap over the central portion of the Ahklun Mountains and deposited moraines at or beyond the modern coast. These moraines have slope angles averaging about 11° and crests averaging about 35 m …

Pattern And Process In Volcano Seismology, John Paul Benoit

Theses (Unassigned)

The patterns of occurrence and the underlying processes of two important seismological phenomena at volcanoes, earthquake swarms and volcanic tremor, were investigated. A global database of volcanic earthquake swarm parameters was compiled and was used to evaluate the March 10-14, 1996 seismo-volcanic crisis at Akutan Volcano, Alaska. Earthquake swarm durations and magnitudes were compared with eruptive activity using this database. Trends identified using the database suggest that the Akutan swarm was not precursory and, no eruption occurred. We postulate that a deep instrusion with a large opening component occurred under the flanks of Akutan. The global swarm database has provided …

The Geomorphological History Of An Alluvial Fan Complex In Nelson County, Virginia, Melinda Ann Youngblood

OES Theses and Dissertations

An alluvial fan complex blankets a portion of the Rockfish Valley in Nelson County Virginia, located along the eastern slope of the Blue Ridge Mountains. The seven-km² field area contains three mappable relict alluvial surfaces (Qf1, Qf2, and Qf3) and one modern surface (Qa1), each of which is underlain by fluvial deposits dominated by greenstone and charnokite cobbles. The four surfaces were mapped according to topographic position and degree of stream dissection. Alluvial deposits underlying each surface were characterized using a 3-part clast weathering scale based on greenstone clast weathering rinds and using soil development criteria (clay content, Munsell …

Error Characterization Of The Alpha Residuals Emissivity Extraction Technique, Michael Baglivio

Theses

When dealing with remotely sensed images, a parameter that aids in material identification is its emissivity. By extracting a materials emissivity spectrum, the probability of correctly identifying it greatly increases. The Alpha Residual algorithm was developed for just such a process. The Alpha Residuals emissivity extraction technique was originally developed for six channel Thermal Infrared Multispectral Scanner (TIMS) data. In dealing with TIMS data, it is known that the error at 300K is 1%. In recent years, detector technology has led to sensors with higher spectral resolution and an increased number of bands. The goal of this project is to …

An Evaluation Of Methods For Identifying And Interpreting Buried Soils In Late Quaternary Loess In Alaska, Daniel R. Muhs, Thomas A. Ager, Josh M. Been, Joseph G. Rosenbaum, Richard L. Reynolds

United States Geological Survey: Staff Publications

The presence of buried soils in Alaskan loess is controversial, and therefore criteria for identifying buried soils in these deposits need to be evaluated. In this paper, morphologic and chemical criteria for identifying buried soils are evaluated by studying modern soils developed mostly in Holocene loess under tundra, boreal forest, and transitional coastal-boreal forest vegetation in different parts of Alaska. Data from modern Alaskan soils that developed under vegetation similar to that of the present indicate that soil morphology, organic-matter concentrations, and P concentrations can be useful diagnostic tools for identifying buried soils. Soil morphologic criteria, particularly horizon colors and …

Pliocene And Pleistocene Marine Ostracoda Of The Limon Basin, Costa Rica: A Record Of Paleoenvironmental Change., Pamela Frances Borne

LSU Historical Dissertations and Theses

Late Pliocene (3.8-3.6 Ma) and early Pleistocene (1.5-0.9 Ma) marine ostracodes of the Rio Banano, Quebrada Chocolate and Moin Formations (Limon Group) provide a detailed paleoenvironmental record for the Limon Basin, Costa Rica. The marine ostracode assemblages recovered from the Limon region do not provide evidence that the tropics cooled dramatically during the late Pliocene when the Northern Hemisphere was entering the Modern Ice Age. Paleoenvironmental interpretations are based on cluster analyses and a modern tropical ostracode analog analysis. Diverse ostracode assemblages of the middle Pliocene Rio Banano Formation are dominated by genera typical of the inner to middle neritic …

Geochemistry And Origin Of The Oligocene Binkılıç Manganese Deposit;Thrace Basin, Turkey, Ali Haydar Gülteki̇n

Turkish Journal of Earth Sciences

Many Oligocene Manganese deposits are found in the Trace basin, a Tertiary collisional-collapse type basin in the northwestern part of Turkey. All the mineralizations are originally sedimentary type. The most economically important deposits are around Çatalça; of these, the Binkılıç manganese ore occurs conformably within the Oligocene fossiliferous formations, as a stratiform type manganese deposit. The manganese ores at Binkiliç show a continuity along strike and consists of micro-to Cryptocrystalline pyrolusite, psilomelane, radial manganite, cryptomelane, wad, rhodochrosite and dispersed organic matter, calcite, feldspar, clay minerals, and quartz but generally only minor quantities of limonite and goethite. Mn oxides with variable …

Application Of The Correspondence-Type Geostatistical Analysis On Theco, Ni, As, Ag And Au Concentrations Of The Listwaenites Fromserpentinites In The Divrigi And Kuluncak Ophiolitic Mélanges, Ali̇ Uçurum

Turkish Journal of Earth Sciences

The main aim of this research was to find out correlation-if there is any-among Co, Ni, As, Ag and Au concentrations in three different listwaenite sampling sets in Divirigi and Hekimhan areas. The low temperature hydrothermal alteration of serpentinite bodies from the Divrigi and Kuluncak ophiolitic mélanges in the Cürek, Divrigi-Sivas, Güvenç and Karakuz areas, Hekimhan-Malatya, has formed two distinct types of listwaenite. Type I, is silica-carbonate listwaenite, which is dominated by silica+calcite+dolomite+ankerite±magnesite. Type II listwaenite bodies are carbonate listwaenite characterized by calcite+dolomite+ankerite ±magnesite, and lack any significant introduced silica. Correspondence-type geostatistical analysis has been thought to be the best …

"Hades" - A Remarkable Cave On Oldoinyo Lengai In The East African Rift Valley, Gordon J. Davies

International Journal of Speleology

Oldoinyo Lengai is the world’s only active carbonatite volcano, situated in northern Tanzania within the Eastern Rift Valley, al 2.751 degrees S, 35.902 degrees E. It forms an isolated symmetrical cone at the southern end of Lake Natron, with a summit elevation of 2,890 m (9,480 ft). Periodic eruptions of ash and lava have been recorded since about 1880, and with increasing precision during this century since 1904. In 1990 a routine expedition to monitor activity levels at the summit led to the discovery of a remarkable cave located in the crater floor, filled with numerous long delicate pale yellow …

Planning Research On Oman: The End Of Lehi's Trail, Terry B. Ball, Kent S. Brown, Arnold G. Green, David J. Johnson

Journal of Book of Mormon Studies

In February 1998, five Brigham Young University professors spent more than a week together in southern Oman to collect data for future research projects in the area, which seems to correspond to the end of Lehi’s trail in the Old World. Future research must be performed in a professional manner and seek to reconstruct that part of the world in 600 BC. Botanical, archaeological, chronological, mineralogical, geological, and inscriptional studies in the area would depend on acquiring sponsors in Oman and on the availability of resources.

Long Dormancy, Low Slip Rate, And Similar Slip‐Per‐Event For The Emerson Fault, Eastern California Shear Zone, Charles M. Rubin, Kerry Sieh

All Faculty Scholarship for the College of the Sciences

Excavations in a playa along the 1992 rupture of the Emerson fault reveal evidence of two paleoseismic events, with only one large prehistoric rupture in the past 15 millennia. Accelerator mass spectrometer radiocarbon ages of charcoal from playa sediments and from fault‐scarp colluvium directly beneath the playa beds indicate that the last large prehistoric slip event occurred about 9000 ka. Trench‐wall exposures revealed clear evidence of at least one pre‐9 ka rupture at the playa site. The event horizon of this earthquake is between two pedogenic carbonate layers that have radiocarbon ages of 14.8 ka and 24.1 ka, implying that …

Post-Middle Miocene Geologic History Of The Tualatin Basin, Oregon With Hydrogeologic Implications, Doyle Coley Wilson

Dissertations and Theses

The geologic history and sedimentary till of the Tualatin Basin after Columbia River Basalt Group (CRBG) emplacement is assessed and related to groundwater characteristics. The 334 m deep HBD-1 core from the Hillsboro Airport, provides the primary information for sediment characterization and is supported by over 2400 well logs and cores, and four seismic lines. The sedimentary section above the 26 m thick paleosol on the CRBG in HBD-I is divided into two main groups: a 25 m thick section of Missoula flood sediments called the Willamette Silt overlies a 263 m thick finegrained sequence of fluvial Neogene sediments.
