Geology of hill end trough Molong high: The geometry of the Gowan Green Overfold and its relationship to the regional deformational history

Abstract

The Gowan Green Overfold southwest of Mumbil (Fig. 1) , is a downward-facing antiformal syncline (Fig. 2) which is anomalous in the regional upward-facing structures of the Molong anticlinorial zone. Extending north from the overfold for 20 km is a discontinuous belt of overturned beds offset by faults (Figs. 1 and 3; Russel, 1975). The overfold and the overturned beds can be interpreted as a single coherent structure (Fig. 4) with an original strike length of 20 km and a width of 11 km.
