Rocks of the Limpopo tecto-metamorphic complex comprise quartzite (5% of area of basement complex), marble and calc-silicate rocks (10%), melanocratic gneiss (10%), orthogneiss (20%) and quartzo-feldspathic gneiss (55%). Pre-D2 mobilisate constitues 30 per cent of the rocks of the Limpopo regime. The area was reactivated and post-tectonic (late D3) anatectic melts were produced possibly 2000 million years(m.y.) ago. Three periods of deformation are recorded. Evidence for DI-deformation is scant but D2-deformation caused north-south, shallow plunging folds. During D2 folding the rocks either developed or maintained mineral assemblages compatible with the low pressure subfacies of the granulite metamorphic facies. D3-deformation produced mineral retrogression and a transformed north-west trending cataclastic fabric.ย
