Origin and geochemical evolution of localized, high-ferrous-iron zones in the Upper Castle Hayne Aquifer, Beaufort County, North Carolina
(East Carolina University, 2017-04-19)
The Tertiary Upper Castle Hayne Aquifer (UCHA) is one of the most productive aquifers in North Carolina's Coastal Plain; however, localized zones containing high, dissolved-iron concentrations ([greater than]0.3 mg/L) are ...
Review and synthesis of the role of structural arches in the Brazilian Amazon lowlands
(East Carolina University, 2017-01-11)
In tropical South America, the interplay of tectonics, climate, and base-level influences terrestrial sedimentary processes of modern rivers and their antecedents, leading to transport of large volumes of sediment through ...
Back-Barrier Sediment and Hydrodynamic Processes: Insights from Rodanthe, NC
(East Carolina University, 2016-07-20)
Barrier islands are found around the world, and their geomorphic evolution is related to ocean and estuarine processes. Processes including sediment mobilization and shoreline evolution on both the ocean and estuarine side ...
The Relationship Between the Taghanic Unconformity and Marcellus Shale Production in Doddridge and Ritchie Counties, West Virginia
(East Carolina University, 2016-07-27)
The Marcellus Shale, a geologic unit that extends from New York to West Virginia within the Appalachian region, is the source of trillions of cubic feet of natural gas due to organic-rich properties. The formation of the ...
DISTRIBUTION AND TAXONOMY OF MODERN BENTHIC FORAMINIFERA OF THE WESTERN SUNDA SHELF (SOUTH CHINA SEA) OFF PENINSULAR MALAYSIA
(East Carolina University, 2016-07-13)
This study investigates, for the first time, the distribution and taxonomy of modern benthic foraminifera from the western Sunda Shelf, southern South China Sea. The uppermost centimeter of 54 surface sediment samples ...
Petroleum Geology of the Utica/Point Pleasant Play in Washington County, Ohio
(East Carolina University, 2016-07-20)
The early Late Ordovician interval, known as the Utica-Point Pleasant play, in southeastern Ohio is poorly constrained due to limited data sets. A previous study by the Appalachian Basin Oil and Natural Gas Research ...
USING SEDIMENT ORGANIC GEOCHEMISTRY TO INTERPRET LATE HOLOCENE BARRIER ISLAND AND ESTUARINE EVOLUTION, NORTH CAROLINA, USA
(East Carolina University, 2014)
Deconvolving the relationship between meteorological and oceanographic phenomena and associated impacts to coastal systems is critical to understanding the future of coastal systems worldwide. North Carolina's barrier ...
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) ...
Source of saltwater intrusion in the Castle Hayne aquifer on the western part of Bogue Banks barrier island, North Carolina
(East Carolina University, 2014)
Saltwater intrusion is occurring in the confined Castle Hayne aquifer on the western part of the east-west trending barrier island of Bogue Banks, North Carolina. Of eleven municipal wells that are solely screened in the ...
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 ...
