Active subsidence controlled by basement structures in the Maranon Basin of northeastern Peru

Abstract:

The Maranon Basin is located between the Brazilian shield and the Andean foothills. The southern part of the basin, called Ucamara depression, comprises large swamp and lakes, with more or less straight edges and nearly geometrical shapes. The Punga swamp is an historical example of tectonic related subsidence. Large swamps overlay structural blocks limited by faults, and uplifted or pulled down basement structures. The main trend of the swamps is related to the reactivation of basement faults. The implications for the regional geodynamic context are briefly discussed.
