The north Ligurian margin is a complex geological area in many ways. It has witnessed several phases of highly contrasting deformation styles, at both crustal scale and that of shallower cover tectonics, simultaneously or in quick succession, and with significant spatial variability. This complex interplay is mirrored in the resulting intricate...
Forearc systems develop largely offshore above subduction zones between the trenchand the volcanic arc. The associated forearc basins are generally parallel to the trenchand involve vertical movements (subsidence vs. uplift), influencing the dynamics of thewedge. The objectof the study is the Guayaquil-Tumbes forearc basin belonging to...

The offshore Tumbes-Guayaquil forearc basin in the accretionary prism of Northern Peru-Southern Ecuador shows evidence of gravity-driven large-scale deformation systems active during the Late Neogene-Quaternary period. Subsurface data and the construction of eight structural cross-sections show that the ~8 km-thick Oligocene-Quaternary...
Extensional faults are often observed along subduction zones as a response of a margincollapse. However, their role remain underestimated within the structural evolution offorearc systems. In southern Ecuador, the oblique subduction of the Nazca Platebeneath South America led to the formation of the Cretaceous-Miocene NW-SEChongón-Colonche...

Orogens develop in convergent settings involving twoor more continental and/or oceanic plates. They are tra-ditionally defined as zones of crustal deformation associ-ated with mountain building resulting from either accretionof a terrane and/or an arc, continent-continent collision or rift-inversion. However, this definition does not...

The southern Ecuadorian forearc system is related to the subduction of the oceanic Farallon/Nazca Plate beneaththe continental South American Plate since the Late Cretaceous, and currently evolves with the dynamic of atectonic block called North Andean Sliver. To explore the structural architecture and processes controlling theUpper...
