NON-MARINE, LATE EOCENE-OLIGOCENE SEQUENCE STRATIGRAPHY AND CHANGING FLUVIAL STYLE IN THE NORTHERN LLANOS FORELAND BASIN OF COLOMBIA
(2012-12)
The Llanos foreland basin (LFB) of Colombia is the country's most prolific oil producer, with most known oil fields found in anticlines bounded by normal faults. The objective of
the study is to assess the reservoir potential ...
Application of the Rhenium-Osmium Isotope Geochronometer to Neoproterozoic and Paleozoic Organic Rich Mudrocks
(2012-12)
New Re-Os isotope data on organic-rich mudrocks (ORMs) from the Neoproterozoic Upper Fifteenmile Group, Coal Creek Inlier, Yukon Territory, Canada and the Paleozoic Quamby Fm., Turnbridge Borehole, Tasmania yield depositional ...
Lu-Hf and Sm-Nd Systematics of Apollo 17 Sample 78236: Ages, Evolution and Investigations into the Neutron Fluence Correction on the Lu-Hf System
(2012-12)
This thesis presents Lu-Hf, Sm-Nd, and Gd isotope and trace element concentration data of Apollo sample 78236,28. Apollo 17 sample 78236 was selected because it represents an early stage of lunar evolution. Sample 78236,28 ...
Investigation of the Source, Fate, and Transport of Mercury in Hunza River, Northern Areas, Pakistan
(2012-12)
Mercury is one of the most hazardous and toxic elements with a high degree of mobility. Although it occurs naturally, anthropogenic activity can also release mercury to the environment. Globally, the use of mercury in gold ...
Crystal Geyser, Utah: Active Travertine Deposits of a Cold-water Carbon Dioxide-driven Geyser and Related Ancient Deposits of the Little Grand Wash Fault
(2012-08)
An active travertine sloping terraced deposit has been precipitated from the cool waters erupting from Crystal Geyser, located on the eastern bank of the Green River, near the town of Green River, Utah, since 1936. The ...
Multidisciplinary investigations of the Chaman strike-slip fault along the western Indo-Asian collision boundary, Pakistan
(2012-05)
The Chaman left-lateral strike-slip fault bounds the collision zone between Indian and Eurasian plates at the western end of the Himalayan-Tibetan orogen and connects the Makran subduction zone to the Himalayan convergence ...
Isotope systematics of the eucrite Jonzac: A look into the history of the eucrite parent body using the Lu-Hf, Sm-Nd, Pb-Pb, & U-Pb isotopic systems
(2012-12)
The main objective of this research is to understand the history of the eucrite parent body through the isotopic and petrologic study of the monomict eucrite Jonzac. Jonzac is a type 7 eucrite defined by less prominent ...
KINEMATICS ANALYSIS OF LARAMIDE DEFORMATION
(2012-12)
Deformation related to the Late Cretaceous-Early Eocene Laramide orogeny in north-central New Mexico resulted in the formation of the Nacimiento uplift, Gallina uplift, and corresponding faults. In the past thirty years ...
TURTLE ROCKS: DIAGENESIS OF THE HARTSHORNE SANDSTONE
(2012-08)
The “turtle rocks” of the Pennsylvanian Hartshorne Sandstone (Arkoma Basin, northwestern Arkansas) are unusual landforms characterized by polygonally jointed and segmented mounds that resemble turtle shells. Turtle rocks ...
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 ...
