The Gondwanide orogeny was widespread across the southern hemisphere during the Late Permian-Early Triassic. Alexander du Toit described Gondwanide deformation as consisting of asymmetric folding, thrusting and cleavage formation. The uplift and erosion which followed is evidenced by an unconformity across Africa and South America. It is related to the breakup of Gondwanaland. [4]
