Evaluating Himalayan tectonic models using the Almora-Dadeldhura klippe
… and microstructural data to support the critical taper, channel flow, or wedge insertion models for the development of the Himalayan thrust belt. Channel flow is not supported if the timing of the Main Central Thrust (MCT) and South Tibet Detachment System (STDS) are interpreted to be …

Field-based Constraints on the Origin of the Benton Uplift, Ouachita Mountains
… to internal wedge thickening as explained by the critical taper model (Davis et al., 1983; Dahlen, 1990). The Ouachita Mountains Paleozoic strata are cut by steeply-dipping conjugate joints that strike NNW and NNE. The conjugate joint set is inferred to represent north-south shortening parallel to …

Geomechanical and tectonic investigations into the geologic history of Mars at local, regional, and global scales
… formed as an orogenic belt is tested using critical taper wedge mechanics (CTWM). Key physical parameters such as the coefficients of friction for the wedge material and décollement and the pore fluid pressure ratio were varied between reasonable values for these parameters suggested by …

Testing the driving mechanisms for exhumation of the Greater Himalayan zone in eastern Bhutan: Implications of split-stream zircon and monazite geochronology
… a structure as previously described. Moreover, a critical taper-type emplacement model predicts that melt crystallization and metamorphism will occur nearly homogeneously across the section. In contrast, a channel flow-type exhumation model predicts heat advection towards the surface, causing the …

Subsurface Structure, Stratigraphy, and Hydrocarbon Basin Modeling of the Barbados Accretionary Prism
… accretion - that in turn increases the wedge taper angles; 3) areas north of the Tiburon Rise and Barracuda ridge show an increased taper angle from 4°-6° while south of the Tiburon Rise and Barracuda Ridge that contain thick trench sediments or an overfilled subduction trench exhibit lower …

Aspects of deformation in a fold-thrust belt: veins and backstop evolution
… The size and shape of this wedge is defined by critical-taper theory. The bulldozer in an actual fold-thrust belt is called the backstop, and it delineates the hinterland-most end of the fold-thrust belt wedge, and it is where deformation related to the fold-thrust belt ceases. Sandboxes with …
