Influence of the cenozoic tectonics from the Peruvian Forearc on the Morro Solar deformation mechanism by means of structural analysis
Descripción del Articulo
The outcrops from the Morro Solar locality gave birth in the Lower Cretaceous within a purely extensional tectonic regime which changed to a compressional regime linked to an oblique plate tectonic convergence as of the Upper Cretaceous and during Cenozoic era. In order to study the pos sedimentary...

Influence of the cenozoic tectonics from the Peruvian Forearc on the Morro Solar deformation mechanism by means of structural analysisInfluencia de la tectónica cenozoica del Antearco peruano en el mecanismo de deformación del Morro Solar mediante el análisis estructuralAyala Carazas, Luis AlbertoMorro Solar; cenozoic tectonics; peruvian forearc; structural analysisMorro Solar; tectónica cenozoica; Antearco peruano; análisis estructuralThe outcrops from the Morro Solar locality gave birth in the Lower Cretaceous within a purely extensional tectonic regime which changed to a compressional regime linked to an oblique plate tectonic convergence as of the Upper Cretaceous and during Cenozoic era. In order to study the pos sedimentary cenozoic tectonics that superimposed to such outcrops, it has been necessary to collect an important quantity of structural data from surface represented by the geometric orientation of fault surfaces that shows a observable tectonic displacement as well microstructures such slickenlines and kinematic indicators from a fragile environment.
