Tectonic deformations, and in particular vertical movements, recorded by the coastal domain above the Ecuadorian subduction zone reflect a complex geological history. These vertical movements can be quantified at different time scales, at the short-term from the scale of the seismic cycle to many cumulated cycles (100 ka) to the long-term (Ma) by combining tectonic markers. In this fieldtrip, we propose to explore vertical movements through morpho-tectonic markers of coastal uplift (uplifted marine terraces) and sedimentary and stratigraphic markers of formation of the Coastal Cordillera (evolution of forearc basins). This fieldtrip will focus on Manta Peninsula and La Plata Island. The observed markers will be placed in their seismic, tectonic and geological context.
Please note that this fieldtrip will be done in spanish.
