Such widespread high-pressure metamorphism signifies that at some point within the extended history of the Zambezi Belt this region was topic to tectonothermal regimes similar to these of subduction zones or maybe ‘A’ kind excessive-strain (HP)-extremely-high-stress-metamorphic (UHPM) belts ( Maruyama et al., 1996 ). The current interpretation of the Zambezi Belt tectonothermal cycles, by Hanson et al. (1993 , 1994) , Vinyu et al. (1997) and Dirks et al.
