Geophysical data and the construction of two balanced cross-sections show that this structural configuration has been controlled by Permian inheritances. A fossilized west-verging Middle Permian fold and thrust belt, which developed during the Gondwanide orogeny, has been partly reactivated by the Andean compression and controlled thick-skinned tectonics propagation. This west-verging thrust system is still active and causes the crustal and damaging seismicity of the Moyabamba region. Late Permian salt, which has sealed the Middle Permian fold and thrust belt, controlled thin-skinned tectonics propagation and the development of the must large overthrust of the Peruvian Subandean zone. The fossilized and partly reactivated Middle Permian fold and thrust belt constitutes a new petroleum play for the exploration in the northern Peruvian Subandean basins. Sub-thrust traps of the Moyabamba and Huallaga wedge-top basins are particularly attractive but stay unexplored. specialized Thin and thick-skinned tectonics Sub-Andes Paleozoic petroleum system Peru Gondwanide orogeny Salt Permian Crustal seismicity PEROU 064 066 82 238-250 2017 0264-8172 https://www.documentation.ird.fr/hor/fdi:010069507 10.1016/j.marpetgeo.2017.02.009 0264-8172 [F B010069507] https://www.documentation.ird.fr/hor/fdi:010069507 https://www.documentation.ird.fr/intranet/publi/2017/05/010069507.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-06-01 2018-01-02 fdi:010069507 fre
