Location: 
Roadside - on the escarpment between Makuti and Chirundu
Stratigraphy: 
Makuti Group
Description: 
Makuti Group paragneisses, exposed within the Zambezi Escarpment.
 
Exposures of paragneisses of the Neoproterozoic Makuti Group which are flat-lying, but highly deformed and metamorphosed. Good examples of boudinage can be seen in quartzo-feldspathic psammitic bends intercalated with politic and semi-pelitic schists. Brecciated dolomitic marbles can be seen close to the escarpment fault. Munyanyiwa et al. (1996) interpreted felsic gneisses (mapped as meta-arkoses by Broderick, 1976) and amphibolites from the Makuti Group as representing a bimodal rift sequence in an intraplate setting. This interpretation was disputed by Dirks et al. (1999), who regarded fine-grained felsic gneisses as representing sheared granitoids.
