Figure 5. Strike section showing the different tectonic sheets laterally. Note that the Pirital-Tala thrust systems (system in blue) are composed of various thrust families separated by lateral ramps. This explains the differences between dip sections that lie in different tectonic sheets. This new interpretation of the Pirital block enabled us to develop the proposition of a new lateral ramp within the Pirital block, delimiting two laterally different tectonic provinces: the Pirital-Cerro Corazon block and the Manresa block.
