A re-interpretation of the Jordan River area mapped by Fyles (19701 suggests that an early Z-shapedfold dominates the structure of the area. The fold (Fig. 9) is cored by biotite schist and grey gncsiss (unit 10 of Fylesl and is postulated to tectonically overlie a younger sequence of gneissic and calcareous rocks (units 4, 5, and 6). This 'younger sequence' is separated from underlying quartzites. schists, and core gneisses (units 1. 2, and 31 by the Bews Creek fault. This re-interpretation allows a revision in the 'lithologic order' suggested by Fyles ( op. cit.). The revised succession comprises three tectonic packages: a Ibasal quartzite sequence (units 2 and 3) above core gneisses (unit 1) overlain (with a tectonic break1 by units 10 through 7 of Fyles, which in turn are overlain by gneissic, calcareous, and schistose rocks of units 6, 5, and 4. This succession is correlated with that along the north and west flank of Frenchman Cap.
