A Thermochronological Investigation of Orogenic Architecture, Kinematics, and Tectonic-Climatic Interactions within the St. Elias Orogen, Alaska
… motion. This structure is interpreted to be a backthrust, making the orogen doubly-vergent. Suggestive of accelerated fault motion in response to climate change, bedrock cooling rates within the hanging wall of the backthrust and across the entire subaerial wedge accelerated ~ten-fold coeval …

Aspects of deformation in a fold-thrust belt: veins and backstop evolution
… in the HVB are associated with the inception of backthrust ramps; 3) Veins develop along flats and forethrust ramps; 4) Vein sets, excluding joint-parallel veins, are associated with folding (including veins formed in association with flexural slip); 5) Fault-parallel veins, as well as veins that …

Tectonics and sedimentation in the Devonian and carboniferous rocks of SW Devon, England.
… is interpreted as a northerly dipping backthrust produced by underthrusting of the Carboniferous foreland basin flysch deposits which become inverted and backthrust towards the south. The above sequence of events is dependent on a thin-skinned tectonic model and can be incorporated into …

Proterozoic Farwell Mountain-Lester Mountain suture zone, northern Colorado : subduction flip and progressive assembly of arcs
… are together referred to as the Farwell Mountain backthrust. Another set of reflections dip southward and project to the surface near Lester Mountain; these are tentatively correlated with the "S2" fabric. Together, these features may record the juxtaposition of two tectonic blocks along …

Structural Geology of the Caddo Gap Area, Ouachita Mountains, Arkansas
… in map view, resulting in a “fishhook.” The backthrust interpretation for Strawn Mountain (Haley et al., 2009) was found to be more structurally complex than previously proposed.</p> <p>Analysis of the Nelson Mountain Anticline shows it is steeply inclined and gently plunging: the calculated …

Field-based Constraints on the Origin of the Benton Uplift, Ouachita Mountains
… Arkansas are most consistent with south-directed backthrusting, as indicated by asymmetric z-folds defined by the Arkansas Novaculite and thrust-duplication of north-dipping Paleozoic strata. Out-of-sequence backthrusting is attributed to internal wedge thickening as explained by the critical …
