The Fowlers Gap and Torrowangee 1:100000 sheets lie to the north of Broken Hill. The two map sheets cover and area of approximately 5200 km2. The aim of this work was primarily the elucidation of the Adelaidean stratigraphy and correlation with similar sequences on South Australia. Information on the Willyama Complex and Late Devonian sediments is mostly from existing thesis work. The area covered by this study is mainly part of the Adelaide Fold Belt: a minor area in the northeast belongs to the Kanmantoo Fold Belt (Scheibner 1974). The Adelaide Fold Belt consists of several. Old, uplifted, fault-bounded anticlinorial blocks which are aspirated by synclinorial zones of relatively unmetamorphosed sediments.
