The Mesoproterozoic Karagwe-Ankole Belt (formerly the NE Kibara Belt): The result of prolonged extensional intracratonic basin development punctuated by two short-lived far-field compressional events

► The Mesoproterozoic Karagwe-Ankole Belt (KAB) has a Western (WD) and Eastern (ED) domain. ► WD and ED are underlain respectively by Eburnean-age and Archaean units. ► KAB reflects an intracontinental history under a transtensional regime with intermittent periods of sedimentation and magmatism. ► Detrital and volcanic rocks identify three distinct sedimentation periods: (c. 1.8 Ga, c. 1.4 Ga and c. 1.2 Ga). ► KAB records compressional events at c. 1.0 Ga (Rodinia amalgamation) and c. 0.55 Ga (Gondwana amalgamation).
