Notes on the Compilation are included within the title. Westerly from singleton and Muswellbrook the areas shewn as Upper Coal Measures may contain the Middle Series. The boundaries of Marine, Carboniferous, Devonian and Silurian rocks north of the Hunter River to the Queensland border are provisional. The rocks delineated as Silurian northwards from Tuena, between Hill End and Wiadere, between Condobolin and Girilambone, westerly from Canbelego, between Camden Haven and Coffs Harbour, between Cape Byron and Murwillumbah may prove to be older. The maps is compiled from detail surveys of the Southern, Western and Hunter Cola Fields, the Tingha, Emmaville and Wilsons Downfall Tin fields, and the Parkes and Cobar Gold Fields, from rapid field observations and all available sources.
