.... The modeling shows that thermal activation during the Permian–Triassic–Jurassic was most intense in the Timimoun basin and the northern part of the Ahnet and Mouydir basins, with a heat flow of about 70–80 mW/m 2 and a lithosphere thickness of 40–50 km. Activation was more moderate in the Sbaa subbasin...
