Using chemical data to define flow systems in Cuatro Cienegas, Coahuila, Mexico
(2005)
The Cuatro Cienegas basin in Coahuila, Mexico was declared a National Protected Area in 1994 by the Mexican government. Its principle uniqueness is in its aquatic fauna, which are dependent on the abundant springs in this ...
Physical modeling of evaporite-detached salients
(2006)
The use of scaled physical modeling of thin-skinned fold-and-thrust belts allows isolation of key parameters in the development of convex-toward-the-foreland folds and thrusts. Unlike salients formed in natural settings, ...
The origin and properties of mass transport deposits, Ursa Basin, Gulf of Mexico
(2009-12)
Uniaxial consolidation experiments on Mass Transport Deposit (MTD) and non-MTD core samples from Ursa Basin, Gulf of Mexico, show MTDs have a lower porosity at a given effective stress compared to adjacent non-MTD sediments; ...
Formation and organization of aeolian bedforms
(2004)
Aeolian bedforms represent some of the most intricate land forms on the planet encompassing a variety of scales from wind ripples on the order of centimeters to desert sand seas comprising thousands of square kilometers. ...
High-temperature carbonate replacement mineralization, metamorphism, deformation, and intrusion in the Bryant District, Beaverhead County, Montana
(2003)
The Bryant District, in the southwest Montana fold-and-thrust belt, contains many structurally and lithologically controlled high-temperature carbonate replacement Pb-Zn-Cu-Ag-Au deposits. Laramide crustal shortening ...
Fluvial-deltaic and shallow-marine seismic geomorphology of the West Natuna Basin : implications for reservoir architecture and basin evolution
(2006)
Quantitative seismic geomorphology and morphometric analysis of modern and paleo-landforms are powerful tools for extracting data about geologic history, processes, and fill architecture of terrestrial and marine basins. ...
Petrology of the southwest margin of the Grasberg Igneous Complex, Papua, Indonesia
(2008-08)
The 3 Ma Grasberg Igneous Complex (GIC) of Papua, Indonesia is host to a super-giant porphyry copper-gold deposit. The GIC is shallowly emplaced into folded and faulted limestones that are as young as late Miocene. The ...
Structural analysis and detrital zircon provenance in the western Llano Uplift : implications for a southern collider
(2005-05)
Structural and metamorphic analysis, mapping and detrital zircon geochronology was conducted within the Mesoproterozoic Valley Spring Gneiss, in the western Llano Uplift, along an 8 km section of the Llano River west of ...
Microbial influence on the kinetics of karstification
(2008-12)
The traditional model of karst and cave formation is that of carbonic acid limestone dissolution, where biologically-produced CO₂ in meteoric water reacts with and dissolves limestone. However, an alternative model has ...
Investigation of surface roughness of natural rock fractures using high-resolution X-ray computed tomography and laboratory flow test measurements
(2005-12)
Fluid flow through natural rock fractures is an important - and often dominant - factor in many aquifer and reservoir systems. Rock fractures are rough-walled, and this surface roughness introduces complexities. The ...
