Structural and Subsurface Relationships between the Fort Rixon Greenstone Belt and the Nalatale Granite Pluton, Zimbabwe, as derived from Gravity and Aeromagnetic Data.

The late-Archaean Fort Rixon greenstone belt is one of the smallest greenstone belts of the Zimbabwe craton, with a maximum length of ~20 km and a width of ~10 km. According to Harrison (1969), it can be imagined that successive periods of intrusion and granitisation have encroached upon the belt, causing a progressive decrease in its size.
