Fig. 6

Small-scale mapping of the eastern sidewall of Gallery 08 between gallery metre GM94 and GM106. For location refer to Fig. 4. South-dipping, sub-planar faults developed from moderately SSE-dipping fault planes. The whole system is activated in thrusting mode. The SSE-dipping strongly tectonised zone was reactivated in normal faulting during the excavation phase
