GROUNDWATER FLOW IN THE UPPER CASTLE HAYNE AQUIFER: NUMERICAL SIMULATIONS AND STRONTIUM ISOTOPIC INVESTIGATIONS
(East Carolina University, 2019-10-02)
The Castle Hayne Aquifer System (CHAS) is the most extensively used aquifer system in the North Carolina Coastal Plain. Heavy groundwater withdrawals from the Upper Castle Hayne Aquifer (UCH) have occurred since the 1960’s ...
CHARACTERIZATION AND DEVELOPMENT OF FRACTURE PATTERNS IN DOMED SEDIMENTARY STRATA, PULPIT ARCH, HENRY MOUNTAINS, UTAH
(East Carolina University, 2020-01-10)
Fractures in sedimentary rock can be an important factor in influencing fluid migration in the subsurface. In high-porosity sandstones in the upper crust, deformation such as folding typically results in the production of ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
A Record of Holocene Climate Change from the Sunda Shelf, South China Sea
(East Carolina University, 2014)
Variations in the East Asian Monsoon (EAM) control weather and regional climate conditions in the heavily populated, agriculturally dependent regions of eastern and southeast Asia. The South China Sea (SCS), especially the ...
Holocene Sedimentary Record from the Sunda Shelf off Peninsular Malaysia: Insights from Elemental, Isotopic and Bulk Sediment Magnetic Susceptibility Analyses
(East Carolina University, 2016-04-19)
Post-Last Glacial Maximum (since ca. 20,000 cal yr BP) sediments of the Sunda Shelf (southern South China Sea) are generally thin, with the exception of incised valleys where thicker accumulations tend to occur. These ...
