Archaean (2.71 Ga) migmatitic granitoid gneisses
Grid Ref (WGS84 Lat/Long in decimal degrees)
These are variegated inhomogeneous, polydeformed migmatitic gneisses, with leucocratic quartzo-feldspathic leucosomes and biotitic melanosomes. These migmatitic gneisses are the westernmost dated Archaean rocks of the Zimbabwe Craton. They have zircons which an age of ca. 2.71 Ga (Master et al., 2013a,b)- and they appear to be the source of the 2.7 Ga detrital zircons in the Malaputese Formation meta-arkoses (pink paragneisses), as well as the source of inherited zircons in the Palaeoproterozoic granites intruding the western Magondi Belt. These gneisses would appear to have formed the basement during Magondi Supergroup deposition in the Dete-Kamativi area, and they were intruded by syn-tectonic or orogenic granitoids during the Magondi Orogeny, in what would have been a continental Andean-type magmatic arc.
