Sección geológica del Pacífico al Atlántico a través de Costa Rica

A geological profile spanning Costa Rica, from the Osa Peninsula on the Pacific coast to Punta Cahuita on the Atlantic coast, reveals the distinct tectonic histories of two major basins: the Térraba and Talamanca basins. These basins accumulated over 5,000 meters of Tertiary sediments, forming a regressive megasequence. The Térraba basin exhibits compressive tectonics characterized by thrust scales and inverse faults, with subsidence in its backward part, while the Talamanca basin shows gravitational landslides in its sedimentary cover, leading to significant overlaps at the foot of the Talamanca mountain range on the coastal plain. This study provides a detailed reconstruction of the geological evolution of these basins, offering insights into their tectonic styles and sedimentary dynamics.
