Tectonic control on coarse-grained foreland-basin sequences: An example from the Cordilleran foreland basin, Utah
Figure 1. A: Map of Charleston-Nebo salient and northernmost Book Cliffs showing rock units, thrust faults (dashed where buried), key seismic coverage (gray lines), measured stratigraphic sections (1–7; 8 is location of additional Blackhawk sandstone samples), and wells. Rock units: KTs—Cretaceous–Tertiary strata (North Horn and younger formations), Kmv—Cretaceous Mesaverde Group (Blackhawk, Ca...
متن کاملBurial and exhumation historyof Pennsylvanian strata, central Appalachian basin: an integrated study
An inferred burial and exhumation history of Pennsylvanian strata in the central Appalachian foreland basin is constrained by integrating palaeothermometers, geochronometers and estimated palaeogeothermal gradients.Vitrinite re£ectance data and £uid inclusion homogenization temperatures indicate that burial ofLower andUpperPennsylvanian strata of theAppalachianPlateau inWest Virginia exceeded 4...
متن کاملForeland basin systems
A foreland basin system is defined as: (a) an elongate region of potential sediment accommodation that forms on continental crust between a contractional orogenic belt and the adjacent craton, mainly in response to geodynamic processes related to subduction and the resulting peripheral or retroarc fold-thrust belt; (b) it consists of four discrete depozones, referred to as the wedge-top, forede...
متن کاملErosion-rate determination from foreland basin geometry
The geometry of foreland basins is controlled by a dynamic balance between thrust-belt migration, fl exural subsidence, and fl uvial deposition. To improve our ability to quantify the relationships between tectonics, climate, and foreland basin geometry, I developed analytic solutions for basin topography and stratigraphy using a classic two-dimensional mathematical model of foreland basin evol...
متن کامل(U-Th)/(He-Pb) DOUBLE DATING OF DETRITAL ZIRCONS
Geochronology and thermochronology on detrital material provides unique constraints on sedimentary provenance, depositional ages, and orogenic evolution of source terrains. In this paper we describe a method and case-studies of measurement of both U/Pb and (U-Th)/He ages on single crystals of zircon that improves the robustness of constraints in each of these areas by establishing both formatio...
