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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
