Resumen
"Las rocas correspondientes al ciclo Precuyano, afloran en la sierra de la Cara Cura, sur de la provincia de Mendoza. Es una secuencia volcano-sedimentaria de 419 m de espesor, constituidos por rocas volcánicas y piroclásticas de composición andesítica que se intercalan con conglomerados, areniscas y pelitas moradas. En esta contribución se presentó una sección estratigráfica del ciclo
Precuyano y se realizó un análisis de facies de la unidad. En el área de estudio, el relleno de la misma se caracterizó por el desarrollo de sistemas volcánicos integrados por depósitos de flujos piroclásticos, flujos de bloques y cenizas y coladas lávicas y en menor proporción por depósitos de abanicos aluviales. Los rasgos estructurales de la serranía son controlados por la existencia de anisotropías preexistentes en el basamento que controlaron el desarrollo de las estructuras del rift."
"Volcaniclastic facies of the Precuyano cycle in the north flank of Sierra de la Cara Cura. Mendoza The Precuyano cycle rocks, cropping out in the Cara Cura range, south of the Mendoza province. It´s a volcaniclastic sequence of 419 m thick, which consists of pyroclastic and volcanic rocks of andesitic composition. These facies are interfinguered with purple clastic levels of conglomerates, sandstones. This contribution presents a stratigraphic section of the Precuyano cycle with a detailed facies analysis of the unit. In the study area, basal infilling of the basin is characterized by the development of volcanic systems together with pyroclastic flows, block and ash flow and lava flows and to a lesser extent by deposits of alluvial fans. The main rift structures controlled the location of these volcanic and pyroclastic facies. They correspond to first order structures that followed the pre-existing regional scale anisotropies in the basement."
