Abstract: Article 1 A new Ordovician graptolite locality east of Tarago, New South Wales; The graptolite assemblage indicates an Eastonian age for at least part of the monotonous greywacke shale sequence between Tarago and the Shoalhaven River.
Article 2 The Torrington silexite deposits; Silexite occurs as a number of dykes, sills, and other intrusive bodies in the sediments of the Torrington Pendant in the Late Permian Mole Granite. The Silexite is probably a late differentiate post-dated by pegmatites. The deposits are a potential source of refractory raw materials, fluorite and wolframite.
Article 3- Stratigraphic revisions in the Tarago - Woodlawn - Mount Fairy area; Facies changes are important in at least the lower part of the Middle Silurian-Early Devonian sequence.
Article 4; Dual pipe reverse circulation drilling, Oaklands Basin drilling programme; Good quality core and excellent recovery were obtained in both poorly consolidated and consolidated formations.
