Stratigraphy and palynology of the Oaklands Basin, New South Wales; Recent palynological studies indicate that the Oaklands Basin sequence consists of sediments of possible Carboniferous, and certainly early Permian, late Permian, and mid Triassic age, overlain by Eocene and Oligocene sediments of the Murray Basin. Correlation of sequences in the eastern side of the Coonamble Embayment and the Gunnedah Basin; Six fully cored boreholes have recently been drilled by the New South Wales Department of Mines in central northern New South Wales as part of the Departments coal exploration programme. These holes penetrated the Jurassic sequence of the Surat Basin and the Triassic and Permian sequence of the Gunnedah Basin. The main stratigraphic units intersected are the Permian Boggabri Volcanics, Porcupine Formation, and the Black Jack Formation, the Triassic Wollar Sandstone and the Wallingarah Creek Formation and Pilliga Sandstone. These units have been correlated throughout the region covered by the drilling.
