  abstract = {{T}he {N}eogene evolution of the {E}ne and southern {U}cayali basins of the {S}ubandes has been controlled by two stacked thrust wedges that differ in terms of tectonic styles. {T}he lower thrust wedge is formed by deep-seated decollements within the basement related to thick-skinned foreland structures inherited from an {E}arly {C}arboniferous thrust system. {S}eismic reflection data show that this {P}aleozoic compressional system has been eroded and unconformably covered by {L}ate {C}arboniferous clastic sediments. {I}t generated an irregular {P}aleozoic sedimentary architecture controlling the {N}eogene thrust propagation. {T}he upper thin-skinned thrust wedge developed within this {P}aleozoic sedimentary series and constitutes the {S}ubandean zone. {C}ross-section balancing shows an along-strike homogenous horizontal shortening of similar to 56 km (similar to 30%) across the {E}ne-southern {U}cayali thrust system. {T}his amount of shortening was vertically partitioned onto the two stacked thrust wedges. {T}he {N}-{S} thickness variations of the {P}aleozoic sedimentary prism controlled the eastward propagation of the upper thrust wedge. {T}he southern thickening of the {P}aleozoic series generated major decollements and the shortening excess is of 7 km (16%) in comparison to the north. {C}onsequently, the northern lack of shortening onto the upper thrust wedge was transferred to the {E}arly {C}arboniferous compressional structures of the lower thrust wedge. {W}e suggest that this vertical partitioning of the shortening was accommodated by a regional oblique ramp: the {T}ambo transfer zone. {T}his geometrical analysis of the {E}ne-southern {U}cayali thrust system provides new perspectives for future hydrocarbon exploration in this region.},
