Two Gondwana paleogeographic reconstructions of two time spans (Late Carboniferous-Early Permian and Late Permian-Early Triassic) were made on the basis of paleomagnetic poles of different continents. Vectorsof motions were determined between the reconstructions of both time spans and it was observed that theywere similar to strain patterns recognized in four Argentinian Geological Provinces (including Ventana fold belt). It is analyzed a model that includes two slab pulls: one in northern Pangaea and the other one in the north margin of Paleotethys ocean. Both processes could be involved during the deformation of Ventana fold belt that would include lateral strike-slips along intra-continental faults.
