Abstract: Scaled sandbox models are used to simulate the development of´basement´-controlled, salients. We investigate the controlling factors on the development of closed curvatures in map-view, considering constant both the sand pack thickness and the space between obstacles. These models are compared with the Fundão-Cambotas Fault System in the Proterozoic fold-thrust belt in the Quadrilátero Ferrífero region, along the southeastern margin of the São Francisco craton. In the experiments, a pronounced curvature result… Show more

“…Both variation in the rheology of detachments and pre-existing basement obstacles in the foreland may influence the map-view curvature of thrusts in sand models (Gomes et al, 2003). In our experiment, deflection and rotation of the frontal detachment was likely influenced not only by the geometry of the frontal escarpment, but also by differential slip along the detachment of glass microbeads located at two different levels in the model (Fig.…”

“…The South Fork thrust (IdahoWyoming-Utah thrust belt) formed over an oblique ramp and underwent deflection and rotation in plan view with shortening both in the general transport direction and in a direction at a high angle to the ramp's strike (Apotria, 1995). The convex-tothe-foreland, west-vergent Fundão-Cambotas Fault System emplaced over Archean basement highs was found to be partly a consequence of the interaction of propagating thrusts with obstacles in the foreland (Gomes et al, 2003). The geometry of the thrust belt in plan view may thus provide insight into predeformational basin geometry.…”
