... of the lower plate are intensely deformed, being tightly folded and cut by thrusts ( Fig. 4 ). Bevan (1929) appears to have been the first to recognize the general extent of the Disturbed Belt in this area. Considering the lack of detailed mapping at the time of his work, Bevan had a remarkable insight...
