WebOct 30, 2007 · Surface processes are assumed to be glacially dominated, and tectonic activity is controlled by critical wedge mechanics. In these circumstances, we find that orogen width is strongly dependent on both the rate of accretion and on the rate of precipitation. ...

WebDec 5, 2016 · The critical taper angle ( α + β) of a horizontally compressed wedge (as shown in Fig. 4) is governed by the force equilibrium of a slice in the x direction. There is … WebIn mechanics and geodynamics, a critical taper is the equilibrium angle made by the far end of a wedge-shaped agglomeration of material that is being pushed by the near end. The angle of the critical taper is a function of the material properties within the wedge, pore fluid pressure, and strength of the fault along the base of the wedge.

Web[1] At many subduction zones, accretionary complexes form as sediment is off-scraped from the subducting plate. Mechanical models that treat accretionary complexes as critically tapered wedges of sediment demonstrate that pore pressure controls their taper angle by modifying basal and internal shear strength. In mechanics and geodynamics, a critical taper is the equilibrium angle made by the far end of a wedge-shaped agglomeration of material that is being pushed by the near end. The angle of the critical taper is a function of the material properties within the wedge, pore fluid pressure, and strength of the fault (or décollement) along the base of the wedge. In geodynamics the concept is used to explain tectonic observations in accretionary wedges. Eve…
