Assessing the shallow groundwater system as a potential factor in generating storm-water runoff on a North Carolina barrier island
(East Carolina University, 2013)
The town of Emerald Isle, located in North Carolina's Outer Banks, experiences significant storm-water runoff and flooding problems during the fall and winter months. The topography of the island influences drainage patterns ...
Timing, internal flow characteristics, and emplacement mechanisms of the intrusive sheet network on the southern margin of Mount Hillers, Henry Mountains, southern Utah
(East Carolina University, 2015)
The exceptional 3-d exposures of the mid-Tertiary intrusive sheet network on the southern margin of Mount Hillers, Henry Mountains, southern Utah, have undergone no syn- or post-emplacement deformation. The sills and ...
Holocene Evolution of the Ocracoke Inlet Flood-tide Delta Region, Outer Banks, North Carolina
(East Carolina University, 1/13/16)
Numerous studies have been conducted along the Outer Banks (OBX) barrier islands of North Carolina to address Holocene climatic change using a combination of lithological, micropaleontological, stratigraphical, and ...
Extension of the Late Holocene Sea-Level Record In North Carolina, USA
(East Carolina University, 2015)
Future sea-level rise will dramatically affect coastal landscapes and populations. The coast of North Carolina (USA) is particularly vulnerable to sea-level rise because its low-lying coastal plain is expansive, has a low ...
THE MARCELLUS SHALE: EROSIONAL BOUNDARY AND PRODUCTION ANALYSIS, SOUTHERN WEST VIRGINIA, U.S.A.
(East Carolina University, 1/13/16)
The Middle Devonian Marcellus Shale is a natural gas producing formation that was deposited in the Appalachian foreland basin in what is now eastern North America. An unconformity truncates the Marcellus in southern West ...
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 ...
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 ...
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 ...
Geometry and Progressive Development of a Shallow Crustal Intrusive Complex, Mount Hillers, Henry Mountains, Utah
(East Carolina University, 2014)
The Henry Mountains of southeastern Utah are five topographic domes, each of which is a separate mid-Tertiary shallow crustal intrusive complex comprised of a cluster of component igneous intrusions. The intrusions were ...
