The SW Ecuador‐NW Peru forearc region is the southernmost location, where the Caribbean large igneous province (CLIP) interacted with the South American margin since the Late Cretaceous. The accretion of the CLIP to the margin led to the entrapment of the North Andean crustal Sliver, conforming the underlying basement of the forearc region in Ecuador, whereas in NW Peru, forearc depocenters involve rocks of continental affinity. Many existing tectonic reconstructions have treated these two areas independently, largely based on their crustal affinities. In contrast, this study integrates previous studies into an analysis of unpublished seismic profiles, potential field data, outcrop stratigraphy, and recent studies dealing with the dynamics of allochthonous terrane accretion along continental margins. Our integrated approach shows that SW Ecuador was dominated by a Late Cretaceous deforming outer wedge, which may have constituted a remnant of a northeast or northwest dipping obliquely obducted oceanic block at the edge of the CLIP. This tectonic phase was governed by plate instability, affecting NW Peru and SW Ecuador, followed by reestablishment of the margin by early Eocene. The resulting margin configuration and the spatial distribution of the different tectonic elements seem to have played a key role in the further Cenozoic development of the forearc region. The model presented in this study proposes that the accretion of buoyant oceanic terranes may have had a profound impact on the early margin configuration of SW Ecuador and NW Peru and led to the development of localized but genetically related forearc depocenters

Ecuador offers a remarkable opportunity to study the evolution of forearc basins installed on accreted oceanic plateau. The interpretation of a network of industrial 2D-Multichannel Seismic Reflection profiles, calibrated with borehole data and regional stratigraphy, allowed to determine the main stages of the forearc evolution. The pre and syn-accretionary stages were documented in the current inner basins by Campanian volcanoclastic deposits sourced by the volcanic island arc which topped the oceanic plateau. NE dipping thrusts ruled shortening at the beginning of the oblique collision between the oceanic plateau and continental plate. Reverse faults and folds are synchronous with a regional erosion linked the end of the accretion during the early-middle Eocene. The forearc sensu-stricto domain is established coeval with the subduction of Farallón plate under South American plate. A regional extensional regimen initiated the double forearc basin configuration along the future Coastal Cordillera during the early Neogene. This phase coincides with the subduction of the Nazca plate, which marks the initiation of modern forearc basins. The basin subsidence during the Miocene was led by the orogenic building effects of the Andean reliefs. The segmentation of the margin is a response of regional uplifts related to strike-slip and reverse reactivation of inherited crustal faults during the Plio-Pleistocene ages. The collision and subduction of the Carnegie ridge explain the forearc segmentation and the coeval Costal Cordillera exhumation. This study provides a remarkable example of the evolution of a non-accretionary-type forearc basin influenced by volcanic ridge subduction
