Unfortunately, these opportunities come at a time of intense financial pressure on the funding sources for research on sedimentary basins. Journal of Archaeological Science, v.
Journal of Geology, v. The composition and age of detrital minerals provide clues to the nature of mountain belts that have long since eroded. Dehler Assistant Professor, Ph. Jewell is also doing preliminary work in the central Idaho batholith.
American Association of Petroleum Geologists Bulletin 83, no. Fact Sheet2 p. Details of channel morphology from the latest spring runoff or flash flood are clearly visible as a number of large boulders.
Ocean Drilling Program Scientific Results, v. To demonstrate the potential of this technique for mineral exploration, we examined geochronologic data from basins with exceptionally large mineral deposits hosted by sedimentary rocks. This volcanic phase was followed by sedimentary infilling of the basin that we equate to the thermal subsidence phase.
Mineralization occurred when sea-level rise and basement subsidence combined to allow Mn-bearing, reducing bottom waters from the Gulf of Mexico to enter the basin GSA Abstracts with Programs, v.

Publications Stanley, Richard G. American Association of Petroleum Geologists Bulletin, v. Spatial analysis of channel-belt stacking patterns: See the publications page for details about specific studies. Previous and ongoing work by Romans and collaborators have used the detrital record and basin-filling patterns of the Magallanes Basin to better constrain the tectonic evolution of the sediment source area, the Cretaceous Patagonian Andes.
Geological Survey Professional PaperChapter 8, 65 pp. The river delta was the site for some of the first human occupants in the Great Basin. Geological Survey Open-File Report12 p. Leg Shipboard Scientific Party,Arc volcanism and rifting: Scroll bars of the Old River Bed Channel below Tectonic and Climatic Control of Alluvial Systems Subtle features are often revealed by the patterns of alluvial systems and their associated sedimentary features.
It is thus an excellent natural laboratory for quantifying the relative role that tectonics, climate, and catchment characteristics play in controlling sedimentary architecture.

This spectacular set of spits in the Deep Creek Mountains of western Utah show highly differential erosion patterns between the Bonneville and Provo shorelines Modern Alluvial Systems The Department of Geology and Geophysics recently acquired a Phantom 3 quadcopter and high resolution camera that can be applied to a number modern alluvial settings.
Much of their effort is focused on understanding and predicting basin formation within the framework of plate tectonics and mantle convection; hydrocarbon generation and migration during basin evolution; present and historic ground-water flow and chemical transport; changes in basin fill and thermal evolution with tectonic environment; spatial and temporal variations of subsurface porosity and permeability; and the record of tectonics, climate, and sea-level change preserved in sedimentary basins.
Open-File Report14 p. Decoupled accommodation and sediment supply in the Late Cretaceous Cordilleran foreland basin of southern Utah: The panel recommends that a focused effort be made to develop a comprehensive set of models for studying the origin and evolution of sedimentary basins.

Potential Student Projects Rift Basin Sedimentary Architecture Sedimentary facies and architecture directly reflect the tectonics, climate, and source catchment character of the basins in which they form. The panel finds that there is an emerging research agenda incorporating the concerns of resource identification and extraction together with the issues of global climate change, fluid flow, and geodynamics.A sedimentary basin is a domain of regional subsidence that can be characterized in space, time, and sedimentary fill.
Tectonic subsidence of basins is caused by rifting, flexure, or cooling of the lithosphere. Comparative study on geochemical characterization of the Carboniferous aluminous argillites from the Huainan Coal Basin, China conditions of ancient sedimentary rocks such as shales, argillites, and sandstones (Clavert and Pedersen, ; Because the southern uplift of the Bengbu strata slowed down the southern seawater transgression.

The three sedimentary basins in Nigeria are underlain by continental crust except in the Niger delta, where the basement rock is interpreted to be oceanic crust.
Most of the wells that penetrated the basement are in the Eastern Dahomey embayment of western Nigeria.
