Tracing the Source of Shallow-water Contamination near a Leaky Fault System, Green River, Utah
(2012-08)
The Crystal Geyser includes low-temperature CO2-rich saline water near the town of Green River, Utah. The high salinity of the water in the geyser area has been attributed to either the natural evolution of the aquifer ...
Stratigraphic Controls on the Structural Evolution of the Sierra Madre Oriental Fold-thrust Belt, Eastern Mexico
(2012-05)
Late Cretaceous–Paleogene Laramide shortening within the Sierra Madre Oriental fold-thrust belt (SMO) along the western margin of the Gulf of Mexico is the product of shallow subduction of the Farallon plate beneath the ...
The Dhaulagiri Transtensional Zone: an active fault zone within the Western Nepal Himalaya
(2012-05)
Field mapping and remote sensing in the Dhaulagiri Range of Nepal reveal a regionally extensive active fault zone linking the Tibrikot Fault to the Dhaulagiri Southwest Fault, herein termed the Dhaulagiri Transtensional ...
Detrital Zircon Geochronology of Cambro-Ordovician Siliciclastic Units of the Humber Arm Allochthon, Newfoundland, Canada
(2012-08)
Paleogeographic reconstruction of the Newfoundland area suggests that various arc terranes developed during the opening of the Iapetus Ocean and development of the Cambro-Ordovician Laurentian stable continental margin. ...
Geometry of the Dolpo-Mugu Folds: Implications for the Deep Crustal Structure of Central Nepal
(2012-05)
Current shortening calculations (700-300 km) across the strike of the Himalayan orogen are significantly less than what has been predicted by plate reconstruction models and other regional studies (1200-800 km). This study ...
MID-ATLANTIC RIDGE (12~16oN) BATHYMETRIC ANALYSIS BY EMPIRICAL MODE DECOMPOSITION
(2012-05)
The study represents an analysis of bathymetry at and proximal to the Mid-Atlantic Ridge (MAR) between 12°40’~16°15’N, 44.4~45.6°W, where are large bathymetric data set exist in a region where Oceanic Core Complexes have ...
MULTIDISCIPLINARY INVESTIGATION OF SURFACE DEFORMATION ABOVE SALT DOMES IN HOUSTON, TEXAS
(2012-05)
Surface deformation has been an ongoing problem in the Houston Metropolitan area because of the city’s location in a passive margin where faulting and subsidence are common. According to previous studies the causes of the ...
The Brazilian Equatorial Margin from Rift to Drift: Faulting, Deposition, and Deformation in the Offshore Barreirinhas Basin
(2012-12)
The Equatorial South Atlantic contains elements of an oblique-rifted margin and a sheared margin. The Barreirinhas Basin is a basin on the Brazilian coast located north of the shoreward limit of the Romanche Fracture Zone ...
Effects of catastrophic blowdown on headwater streams of the Routt National Forest, Colorado
(2012-08)
My study focuses on the effects of a severe storm event on headwater mountain stream morphology. In 1997 the Routt Divide Blowdown felled 13,000 acres of trees in the Routt National Forest, Colorado, causing massive amounts ...
ASPECTS OF THE FORMATION AND EVOLUTION OF RIFTED MARGINS: SEGMENTATION, UPLIFT AND POST-BREAKUP DEFORMATION
(2012-12)
In this study, aspects of the incipient stages of continental rifting, of rift zones around the time of continental breakup, and of mature rifted margins are evaluated. We focus on structural segmentation at incipient ...
