Effects of Urbanization on Stream-Riparian Zone Connection along Low Order Coastal Plain Streams of North Carolina
(East Carolina University, 2017-07-18)
Headwater stream reaches, vital areas of exchange between upland and aquatic systems, are commonly affected by stream burial because they constitute a large fraction of total stream length and are more economically feasible ...
Sorption of Ibuprofen to Coastal Plain Soils
(East Carolina University, 2017-07-18)
The transport and fate of pharmaceuticals and personal care products (PPCPs) in terrestrial and aquatic ecosystems has become an area of concern in the environmental science community. Due to advances in analytical technology, ...
A re-examination of hydrothermal alteration and Fe-Ti oxide relationships in the Skaergaard Layered Mafic Intrusion, East Greenland
(East Carolina University, 2018-05-01)
Fractionation between Fe isotopes in igneous systems and hydrothermally-altered rocks is small but significant, and detailed petrographic understanding of rocks is needed to discern the origin of such fractionations. One ...
GEOLOGY AND ORIGIN OF SAND RIDGES IN A BACK-BARRIER ESTUARY, PAMLICO SOUND, NORTH CAROLINA
(East Carolina University, 2018-06-06)
The Outer Banks of North Carolina have undergone significant geomorphic change, exhibiting varying degrees of barrier island continuity during the late Holocene. These changes affect the environmental conditions (salinity, ...
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 ...
Geometry and construction history of a complex intrusive center in the shallow crust, Mount Pennell, Henry Mountains, Utah
(East Carolina University, 2014)
Large igneous intrusions grow from incremental emplacement of relatively small batches of magma. The Henry Mountains have been the subject of investigation because multiple, well-exposed intrusive centers are present on ...
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 ...
Mineralogy, Geochemistry, and Genesis of the Valentines Iron Formation, Nico Pérez Terrane, Eastern Uruguay, and Significance for the Redox Conditions of Early Earth's Oceans
(East Carolina University, 2015)
The Valentines Iron Formation of eastern Uruguay is one of three well-defined rock units that comprise the Valentines Formation, and is commonly interlayered with felsic and intermediate granulites. The iron formations ...
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 ...
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 ...
