Subsurface mapping and 3D flexural modeling of the Putumayo foreland basin, Colombia
The Putumayo foreland basin (PFB) is located in southernmost Colombia and forms a 250-Kmlong segment of the 7000-Km-long corridor of Late Cretaceous-Cenozoic foreland basins formed by the eastward thrusting of the Andean mountain chain over Precambrian rocks. The current daily production of the …

The Lower Pennsylvanian New River Formation: a Nonmarine Record of Glacioeustasy in a Foreland Basin
… sedimentary rocks of the central Appalachian Basin consist predominantly of nonmarine, coal-bearing facies that developed within a fluvio-estuarine, trunk-tributary drainage system in a foreland-basin setting. Sheet-like, sandstone-mudstone bodies (up to 100 km wide and 70 m thick) developed …

Thermo-tectonic record of hyperextension, structural inversion, and foreland basin evolution of the eastern and central Pyrenees
… crustal architecture on orogenesis and foreland basin development. This work constrains the Early Cretaceous hyperextension history along the Iberia-European margin and how rift inheritance affected the structural and foreland basin evolution of the Late Cretaceous-Oligocene Pyrenean …

High-Precision ID-TIMS U-Pb Zircon Geochronology of Three Cenomanian Bentonites from the Western Canada Foreland Basin
The Western Canada foreland basin contains a rich record of Upper Cretaceous marine | and tectonic change, yet is sparse in biostratigraphically useful fauna that permit | continental and global correlation. However, numerous extensive bentonites have been 1 mapped in Cenomanian strata and traced …

Provenance of Eastern Magallanes Foreland Basin Sediments: Mineralogical and Geochemical Analyses Reveal Paleogene Tectonic Unroofing of the Fuegian andes
… composition data from the eastern Magallanes basin of southernmost South America indicate that Campanian to middle Eocene sediments had a mafic/ophiolitic provenance which is interpreted as being derived from the Patagonian-Fuegian magmatic arc and the mafic floor of the preceding Rocas Verdes …

Cenozoic foreland-basin evolution in the northern Andes : insights from thermochronology and basin analysis in the Eastern Cordillera, Colombia
The modern foreland basin straddling the eastern margin of the Andean orogen is the prime example of a retro-arc foreland basin system adjacent to a subduction orogen. While widely studied in the central and southern Andes, the spatial and temporal evolution of the Cenozoic foreland basin system in …

Initial deposition in the Sevier foreland basin of southern Nevada: Conglomerates of the Cretaceous Willow Tank Formation, Clark County, Nevada
… of the Willow Tank Formation is the initial foreland basin sediment that was derived from highlands created by the Sevier thrust belt and dispersed across an irregular surface of Jurassic Aztec Sandstone in southern Nevada. The conglomerate varies from 5.5 to 34.5 m in thickness and is …

DEVELOPMENT OF THE ROCKY MOUNTAIN FORELAND BASIN: COMBINED STRUCTURAL, MINERALOGICAL, AND GEOCHEMICAL ANALYSIS OF BASIN EVOLUTION, ROCKY MOUNTAIN THRUST FRONT, NORTHWEST MONTANA
… Following deposition of the overlying foreland basin clastic-wedge, the grikes were stylolitized by layer-parallel shortening and buckled over fault-propagation anticlinal crests in the Late Cretaceous-Paleocene fold-and-thrust belt. The model proposes that the grikes record uplift and …

Structural Evolution of the Himalayan Thrust Belt, West Nepal
Himalayan foreland basin strata were recently documented to crop out in a structural window in the central portion of the Himalayan thrust belt. Presently, structural interpretations of the thrust belt do not explain in detail how these strata were incorporated into the thrust belt and why they are …

Gravity Modeling, Seismic Stratigraphy, and Thermal Maturity Modeling of Hydrocarbons of the Permian Foreland Basin, USA, and the Sergipe-Alagoas Rifted-Passive Margin, Brazil
The Permian Basin in West Texas is by far the most prolific oil-producing onshore basin in the U.S., and the Sergipe-Alagoas Basin is the sixth-largest hydrocarbon-producing basin in Brazil. The purpose of this dissertation is to better understand the changing tectonic setting, crustal structure, …
