Examining Coastal Marsh Sedimentation In Northeastern North Carolina
(East Carolina University, 2015)
Coastal marshes are critical environments that are ephemeral on geologic timescales. Understanding the dynamics that naturally maintain these systems is becoming increasingly important in the face of accelerated sea-level ...
Geometry and Construction History of the Copper Ridge Laccolith, Mount Ellen, Henry Mountains, Utah
(East Carolina University, 2015)
The Copper Ridge laccolith is an asymmetric tongue-shaped intrusion located on the southeastern margin of Mount Ellen in the Henry Mountains, Utah. The late-Oligocene to early-Miocene igneous rocks have no syn- or ...
The Contentnea Creek Granite : Constraints On Late Paleozoic Magmatism And Deformation, Eastern Piedmont Fault System, North Carolina
(East Carolina University, 2015)
The Alleghanian orogeny is manifested in eastern North Carolina by dextral transpressional faulting on the Eastern Piedmont Fault system and spatially associated granitic magmatism. The Contentnea Creek granite in Wilson ...
Modern Sedimentation And Estuarine Shoreline Change Around Roanoke Island, North Carolina
(East Carolina University, 2015)
Croatan and Roanoke sounds in North Carolina (NC) are regions constantly undergoing geomorphic changes associated with sea-level rise, storm events, and anthropogenic modification. These estuaries are part of the larger ...
EXAMINING THE IRON ISOTOPE GEOCHEMISTRY OF OLIVINE IN THE SKAERGAARD LAYERED MAFIC INTRUSION, EAST GREENLAND
(East Carolina University, 2018-07-24)
Despite reports of significant fractionation of iron isotopes occurring under magmatic and hydrothermal conditions, the mechanisms that cause and control fractionation in magmatic systems remain poorly understood. Previous ...
THE INFLUENCE OF FRACTURE CHARACTERISTICS ON GROUNDWATER FLOW SYSTEMS IN FRACTURED IGNEOUS AND METAMORPHIC ROCKS OF NORTH CAROLINA (USA)
(East Carolina University, 2013)
The yield of water wells drilled in crystalline rock aquifers is determined by the occurrence and interaction of open, saturated fractures which decrease with increased depth, outside of the influence of large-scale features ...
MAJOR AND TRACE ELEMENT CHEMICAL COMPOSITION OF GAHNITE FROM GRANITIC PEGMATITES AND A METAMORPHOSED MASSIVE SULFIDE DEPOSIT : SIGNIFICANCE FOR PEGMATITE FRACTIONATION AND DISCRIMINATION BETWEEN Li-RICH AND Li-POOR PEGMATITES
(East Carolina University, 2014)
Rare-element granitic pegmatites are common hosts to economic deposits of rare metals, including Li, Ta, and rare-earth elements, which are increasing in economic importance due to advancing technology. Gahnite (ZnAl₂O₄) ...
Decadal-scale evolution of a barrier island : Insights from storm overwash and shoreline change on Ocracoke Island, NC
(East Carolina University, 2014)
Eastern North Carolina has over 300 km of barrier islands that comprise the Outer Banks and act as an important buffer from the Atlantic Ocean and boundary to the Albemarle-Pamlico Estuarine System. These islands also draw ...
Holocene Stratigraphy and Paleoenvironmental Change of Pamlico Sound, North Carolina, USA
(East Carolina University, 2014)
Understanding how coastal systems respond to changes in climate is becoming more important due to the current increased rate of sea-level rise and possible increased hurricane intensity in the future. While coastal ecosystems ...
Geophysical characterization of onsite wastewater treatment system effects on groundwater quality, eastern North Carolina
(East Carolina University, 1/13/16)
Onsite wastewater treatment systems (OWS) are a potential non-point source of pollution that can result in water quality degradation in groundwater and surface water. Locating OWS wastewater plumes in the subsurface often ...
