Foreland basin stratigraphic control on thrust belt evolution
The link between orogenic activity and foreland basin stratigraphy is well established; however, potential controls by foreland basin stratigraphy on thrust belt architecture have not been fully evaluated. Mechanical properties of typical foreland basin stratigraphic successions influence the structural development of fold-thrust belts in predictable ways. Fundamental features of foreland basin...
متن کاملLinking Taiwan’s subcritical Hsuehshan Range topography and foreland basin architecture
[1] The contemporary presence of the Puli Topographic Embayment within the Taiwanese thrust belt provides insight into processes that initiate and maintain a subcritical state in a thin‐skinned compressive wedge. Orogen‐scale analyses of Taiwan have succeeded in describing the processes and interactions that affect overall development of the thrust belt; however, relatively little is known abou...
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 کاملTectonic 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 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...
