Southern Alaska crustal exposures provide an excellent opportunity to study the growth of collisional continental margins through the processes of terrane accretion, magmatism, accretionary prism development, and subduction of oceanic...
The study conducted U-Pb isotopic dating of the pitchblende mineralization of the Coles Hill uranium deposit in Pittsylvania County, VA. The ore body is found along the Chatham fault and within the Martinsville Igneous Complex. In...
A data assimilation method is developed to calibrate a heterogeneous hydraulic conductivity field conditioning on observation of a transient groundwater flow field or transient conservative solute transport field. An ensemble Kalman...
The Hengchun Peninsula (HCP) of southern Taiwan represents the newest emergent segment of the orogen built by the ongoing oblique collision between the Luzon arc and Eurasia continent. Newly recognized exposures indicate that a unit with...
The goal of this project is to combine gravity measurements with geologic observations to better understand the "Big Bend" of the San Andreas Fault (SAF) and its role in producing hydrocarbon-bearing structures in the southern Central...
The thesis presents and evaluates five new gravity constrained structural cross-sections about the Palos Verdes and Cabrillo faults of southern California. They both have been active since the Miocene, however the Palos Verdes fault zone...
Wakulla Springs, located in the Woodville Karst Plain (WKP) of Florida’s Big Bend, is a complex phreatic cave system characterized by convoluted, irregular, conduit geometry—reaching depths between 45 meters to 90 meters (Werner, 2001)....
The dissertation presents a series of hydrogeological studies related to mixing of lake water and groundwater in the Upper Florida aquifer system. In the study area located in the Northern Highland of Florida, two sinkholes were...
Geological, Geophysical, and Hydrogeological Investigation of the Underground Source of Drinking Water (USDW) Line to Support Deep Well Injection, Northern Pasco County, Florida
The underground source of drinking water (USDW) is an aquifer or part of an aquifer, that supplies Unites States citizens with public drinking water. A USDW must contain water that is recoverable, and the water must possess a...
The overall goal of this project is to better understand geologic characteristics of the Raton Basin. The Raton Basin is a Rocky Mountain foreland basin that contains Pennsylvanian through modern sedimentary rocks. The current structure...
This project seeks to determine how the opening of the Red Sea rift was influenced by pre-existing tectonic features and to place constraints on the structural evolution of the western Saudi Arabia margin. In detail, we investigate...
A Study of the Lithological and Petrographical Changes Across the Eocene-Oligocene Transition of the Ocala and Suwannee Formations in Northern Florida and Southern Georiga
With so few Eocene outcrops throughout Florida, it is difficult to study the Eocene-Oligocene boundary between the Ocala and Suwannee Limestone. This study provides a more detailed lithological description of the differences of rocks on...
The Oligocene-Miocene collision between Panama and South America significantly influenced ocean currents, global climate, and species diversification. Intraplate deformation of the Panama Block also played an important role in the...
In the southernmost Appalachians, bimodal volcanics of Pumpkinvine Creek Formation (PCF) and its proposed equivalent, the Hillabee Greenstone (HG) have indistinguishable ages (~460 Ma) and trace element-REE pattern similar to an arc/back...
Incorporation of lime amendments is an effective treatment to neutralize acidity, reduce soluble metals, and facilitate plant growth in mine wastes. In general, arsenic (As) solubility increases with increasing pH in As laden mine wastes...
