dc.description.abstractThe fission track method applied to obsidian samples allows one to determine their geological age by counting etched tracks due to spontaneous fission of Uranium impurities, usually in the ppm-tens of ppm range. Only recently has research in Australian obsidians started, after the discoveries of both artefacts and geological sources, the latter being located mainly in North Queensland and New South Wales. Following irradiation at the nuclear reactor of Pavia University (Italy) the obsidian samples were etched under standard conditions, then the induced fission track density and the uranium content were measured with an uncertainty of an order of 4%. Thermal treatment based age corrections have been applied to get the true age. © The Authors.en_AU
