摘要:ABSTRACT(#br)Lower to upper Middle Ordovician quartz-rich turbidites form the bedrock of the Lachlan Orogen in the southern Tasmanides of eastern Australia and occupy a present-day deformed volume of ∼2–3 million km3. We have used U–Pb and Hf-isotope analyses...

摘要:ABSTRACT(#br)Detrital zircon U–Pb and muscovite 39Ar/40Ar ages from sandstones in the fluviatile to shallow marine mid-Jurassic Clent Hills Group and Wakaepa Formation of mid-Canterbury, South Island, New Zealand, show characteristic patterns that demon...

摘要:ABSTRACT(#br)Uranium–lead age patterns of detrital zircons in Otago Schist meta-sandstones from eastern Otago, including areas of orogenic gold mineralisation, are mostly consistent with a Rakaia Terrane (Torlesse Composite Terrane) accretionary wedge protolith. Southwest of...

摘要:Over 500 zircon grains separated from modern sediments in 10 drainages covering the Eastern Succession of the Mt Isa Inlier have been analysed for U – Pb ages, Hf isotopes, and trace elements, using in situ LAM-ICPMS techniques, to evaluate the efficacy of this approach in c...

摘要:The integrated in situ microanalysis of Pb and Hf isotopic compositions of zircon (TerraneChron® methodology) has been applied to detrital zircons from locally derived stream sediments in the South Para River, which samples the Houghton Inlier, South Australia. The zircons r...

摘要:Two populations of kimberlitic zircon are present in the Timber Creek kimberlites, Northern Territory. Laser-ablation ICP-MS U-Pb dating yields an age of 1483 ± 15 (2σ) Ma for the main group and an age of 179 ± 2 Ma for the other group. This distinction of two age groups is ...

摘要:In easternmost Australia, the New England Orogen contains a geological record dominated by subduction-related rocks, with plate convergence during the Late Devonian to Triassic being related to a west-dipping subduction system, assuming present-day orientation, at the boundary of...

摘要:Geochronology work in New South Wales started with CSIRO's acquisition of a mass spectrometer the 1970s, and initiation of collaboration with Macquarie University. The1988 establishment of the Centre for Isotope Studies (managed by Macquarie) allowed the expansion of these facili...

摘要:Geochemical and Sr-Nd isotope data for Mesozoic greywackes of New Caledonia terranes, indicate a forearc tectonic environment at the Eastern Gondwanaland margin, but they support only minor continental influences. Detrital-zircon U-Pb age patterns for the greywackes in these terr...
