The Camisea fold and thrust belt, located in the southern Ucayali Basin, has been extensively studied due to its important hydrocarbon accumulations. High-quality 3D depth-migrated seismic data allows the identifica-tion of five structural trends in a thin-skinned fold and thrust belt. The main structures are north-verging thrusts with a basal detachment that deepens southward. The San Martin and Cashiriari anticlines, which are the focus of this work, are interpreted as fault-bend folds. In order to analyze along-strike variations of these structures, four cross-sections were made. Besides the north-verging thrusts, high angle reverse faults with opposite vergence can be identified. The analysis of the crosscutting relationships between the different structures allows us to define a sequence of deformation in which the high angle reverse faults precede and are cut by the main north-verging thrusts. A kinematic evolution of the structure is presented in order to verify the correct restoration and validate the structural cross-section interpretation.
