The structures observed in this region are interesting, and unique to areas where rocks of similar ages are found. Similar dome and keel structures are found in the Barberton Greenstone Belt. These structures were interpreted to be the result of partial convective overturn. These lighter colored domes surrounded by the darker colored greenstone belts are easily seen in satellite imagery, and can also be seen in the map above. A cross-section of this structure is provided, and the steeply dipping anticlines and synclines are characteristic of this type of structure. The interior of the granitic domes are mostly undeformed, however the margins and the greenstone belts are heavily deformed, and the metamorphic grade depends on the region's proximity to the dome-keel margins.
