چکیده انگلیسی
The reactivations of the basement record successive uplift events during the Phanerozoic dated via corrected fission track ages, at 387±50Ma (Ordovician); 193±19Ma (Triassic); 142±18Ma (Jurassic), 126±11Ma (Early Cretaceous); 89±10Ma (Late Cretaceous) and 69±10Ma (Late Cretaceous). These results indicate differential uplift of tectonic domains of basement units, probably related to Parana basin subsidence. Six major sedimentary units (supersequences) that have been deposited with their bounding unconformities, seem to have a close relationship with the orogenic events during the evolution of southwestern Gondwana.
