Anticlines (convex-up fold structures in rock layers) are often associated with compressional tectonic forces which cause layers to buckle and fold. Anticlines can also develop when extensional forces produce normal faults in a rock mass, provided the steepness (dip) of the normal faults changes with depth.12.2 Folding. When a body of rock, especially sedimentary rock, is squeezed from the sides by tectonic forces, it is likely to fracture and/or become faulted if it is cold and brittle, or become folded if it is warm enough to behave in a plastic manner. The nomenclature and geometry of folds are summarized on Figure 12.5.Anticlines, thrust anticlines and faulted anticline are often found as traps. Two zones are recommended as exploration targets after careful evaluation, i.e. the western Sub-Andean thrust fold belt and the foothill belt where deeper reservoirs such as those in the Huamampamba Formation and Santa rosa Formation are observed.The structure is a thin, steeply faulted anticline that runs east–west, with two large thrusts cutting it longitudinally.
