The Rhodesian Archaean Craton consists of greenstone schist belts tightly folded between gneiss domes. The Selukwe Schist Belt, situated near the centre of the craton, consists of mainly Sebakwian Group greenstones, ultra-mafics and sediments, older than intrusive 2900 m.y. tonalities. It appears to be part of an imbricated and overturned lower limb of a large recumbent fold, resting allochthonously on a gneissic basement. Four main tectonic slices, separated by mylonite shear zones were recognized. The inverted succession together with the shear zones were refolded during two subsequent tectonic episodes, before being arched and tilted by intrusion of the tonalite diapir in the southeast.
