PGE mineralization at the Allard stock: Implications for the porphyry to epithermal transition, La Plata Mountains, Colorado
(2014-06-06)
Geochemical and petrographic studies on the Allard stock, which hosts a porphyry Cu-Ag-Au-Te-PGE deposit in the La Plata Mountains of southwestern Colorado, suggest mantle sources for both metals and sulfur. Microprobe ...
Koreabama: Exploring the Recent Social and Landscape Impacts of South Korean Migration Trends and Patterns in the Rural South
(2014-04-25)
Korean immigration to the United States has been changing over the last few decades. Historically, Korean immigrants have been characterized by the stereotype of female Koreans seeking marriage to male American military ...
Geology of the Dadeville Quadrangle and the Tallassee Synform in Characterizing the Dog River Window
(2014-03-31)
Structural and lithologic observations are reported for southernmost Appalachian shear zones and Blue Ridge and Inner Piedmont metamorphic rocks exposed on the Dadeville 7.5-minute quadrangle map. Brevard fault zone ...
Characterizing the Geological and Geochemical Properties of Selected Gas Shales and their Thermal Maturation in the Black Warrior Basin, Alabama
(2014-07-22)
This study will focus on selected gas shale’s, geological and geochemical properties in Alabama’s Black Warrior Basin, which contains Cambrian through Mississippian shales; these gas-shales that may potentially produce ...
Geochronology and structural geology of the Kjerringøy Peninsula, Nordland, Norway
(2014-10-30)
Field mapping, structural and petrographic analysis, ID-TIMS U-Pb geochronology, 40Ar/39Ar thermochronology, and chemical dating of minerals were employed to decipher the geologic history of the Salten area of north-central ...
Growth of Alabama Urban Areas and Its Impact on Changing Environmental Dynamics
(2014-07-11)
Urbanization plays a key role in modifying land cover and has widespread impact on the environment. Atlanta has always been the focus of urban studies in south-eastern United States. Little attention is given to urban areas ...

(2014-12-09)
This thesis presents analyses on the intra-site spatial arrangement of two communities from the Hickory Ground site, 1EE89, in Elmore County, Alabama. Spatially referenced archaeological datasets of a Protohistoric community ...
Evidence for a Possible Supervolcano on Mars at Siloe Patera
(2014-05-02)
Highlands on Mars interpreted as impact craters may instead be supervolcanoes
within an ancient volcanic province in Arabia Terra, Mars. These volcanoes are
characterized by lower than normal topographic relief, collapse ...
Trace Element and Hf-Nd Isotope Constraints on the Origin of Young Tengchong Volcanic Rocks, SE Tibetan Plateau
(2014-05-14)
Hafnium and neodymium isotope systematics in mafic volcanic rocks provide useful information about mantle source characteristics and processes. Hf and Nd isotope arrays are useful for identifying the types of subducted ...
