Strike-slip Tectonics Alone the Southern Border of Yalsuaraz BasinMendoza

The Yalguaraz intermontane depression is located between the Frontal Cordillera and Precordillera in the northern Andean region of Mendoza. The Cerro Redondo range (3210' S and 6844' W) displays a thick Siluro-Devonian section intruded by Miocene andesitic bodies at the southern margin of...
