Resumen
The rocks in the Tuape region, north-central Sonora, are intensely faulted and fractured and occasionally folded. Thrust and normal are the commonest fault types and folds are of chevron type. These structures were produced during at least three periods of deformation: Late Jurassic, Late Cretaceous-early Tertiary, and middle to late Tertiary. The first is characterized by intense low-angle faulting and slight metamorphism; the second consists of thrust faulting (?) and emplacement of plutons; the third is typified by basin-and-range normal faulting which generated the present morphological expression of the study area. It is speculated that the complex pattern of tectonic disruption is partially related to the transition from convergence to transcurrent faulting and attendant transpression along the Mojave-Sonora megashear… In order to continue, download the full text in PDF.
