Estudio estructural del piedemonte subandino de la cordillera oriental de Los Andes, Region De San Ramon, Peru
Jean Francois Dumont, Jose Arana
Abstract
Resumen. El piedemonte de los Andes Orientales del Peru Central se caracteriza, en San Ramon, por la acumulacion de capas aluviales conglomeradicas (Formacion Canon) en una paleotopograffa diferenciada, probablemente, al comienzo del Plioceno (Cuenca de San Ramon). Estos terrenos estan deformados por un acortamiento de direccion NE-SW y sobrescurridos por los terrenos mesozoicos de la cordillera, a lo largo del margen flexurado de la cuenca de San Ramon. La reanudacion, en el Cuaternario, de una erosion subsecuente se caracteriza por la aparicion de importantes conos aluviales, al pie de la cordillera. Abstract. On the eastern slope of the Eastern Andes, Central Peru, the Amazonian piedmont is clearly marked by the deposition of a conglomeratic apron (Canon Formation) in a steep paleotopography of probably Early Pliocene age (San Ramon Basin). The Canon Formation was faulted during a NE-SW shortening and overthrusted by the Mesozoic rocks of the Eastern Cordillera, along the western flexured edge of the San Ramon Basin. A piedmont of alluvial cones was formed by the following erosion during Early Quaternary.
