...JanusD. Westraat; AlexanderF.M. Kisters; Marc Poujol; Gary Stevens Abstract Structural, petrographic and geochronological studies show that the tabular 3.1 Ga Mpuluzi batholith in the Barberton granite–gneiss terrane in South Africa was emplaced via a combination of external and internal processes...

... such as the Inyoka-Saddleback fault system. High resolution 2D conductivity images along selected profiles suggest that some faults might continue further south into the granitoids of the Mpuluzi batholith, implying that the batholith was emplaced along faults (Inyoka-Saddleback fault system and/or Komati Fault...

... that the metamorphic history of the Mahamba Gneiss Complex cannot be explained by this model. We propose that deformation and metamorphism occurred through intracratonic contraction and a thermal event possibly related to Mpuluzi batholith emplacement.

This is most likely caused by the transition from the Mpuluzi batholith to the more complex structured BGB units and the overall complex structure of the BGB and its fault system making it harder for the modelled data to fit the measured impedance components.
