Devonian-Carboniferous granites are widespread in Tasmania. In eastern Tasmania, Devonian granites intrude Ordovician-Early Devonian quartz-rich turbidites of the Mathinna Supergroup. The earliest (*400 Ma) I-type granodiorites may be arc-related. Fo

Geochronology and provenance of the Late Paleozoic accretionary wedge and Gympie Terrane, New England Orogen, eastern Australia∗

Autor: Geoff Fraser, David A. Foster, William L. Griffin, Christopher J. Adams, R. J. Korsch, C. G. Murray, Lance P. Black, Chris Foudoulis

Publikováno v: Australian Journal of Earth Sciences. 56:655-685

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 o

Sources of sediment in the Eocene Garford paleovalley, South Australia, from detrital-zircon geochronology

Autor: Lance P. Black, Anthony Reid, B. Hou, R. J. Korsch

Publikováno v: Australian Journal of Earth Sciences. 56:S125-S137

Detrital zircons from the Eocene Garford paleovalley, central South Australia, were derived from two main sources: (i) local Archean–Mesoproterozoic rocks of the Gawler Craton exposed in the paleocatchment, including the 2525–2440 Ma Mulgathing C

Chemical fingerprinting of hydrothermal zircons: an example from the Gidginbung high sulphidation Au-Ag-(Cu) deposit, New South Wales, Australia

Autor: Terrence P. Mernagh, Chris Ryan, Esmé van Achterbergh, Lance P. Black, K.C. Lawrie

Publikováno v: ResearcherID

Hydrothermal zircons occur as an integral component of the alteration and mineralization assemblage in the Gidginbung high sulphidation Au-Ag-(Cu) deposit in the Lachlan Fold Belt, Australia. Their hydrothermal origin is demonstrated by (1) their par

Significance of Devonian–Carboniferous igneous activity in Tasmania as derived from U–Pb SHRIMP dating of zircon

Autor: Lance P. Black, R. J. Korsch, Chris Foudoulis, John L. Everard, M.P. McClenaghan

Publikováno v: Australian Journal of Earth Sciences. 52:807-829

A series of new Sensitive High-Resolution Ion MicroProbe (SHRIMP) U – Pb ages is presented for Palaeozoic (mainly Devonian and Carboniferous) granites from Tasmania. In virtually all instances the new ages are significantly older than previously de

U – Pb zircon ages from leucogneiss in the Etheridge Group and their significance for the early history of the Georgetown region, north Queensland

Autor: J. H. C. Bain, I.W. Withnall, B.S. Oversby, Lance P. Black, P. Gregory

Publikováno v: Australian Journal of Earth Sciences. 52:385-401

The Einasleigh Metamorphics form part of the Etheridge Group and are interpreted as the lowest exposed part of the Georgetown Inlier of north Queensland. Due to a dearth of interbedded felsic igneous rocks that would be suitable for isotopic dating,

Overcoming Proterozoic quartzite sand-body miscorrelations: integrated sequence stratigraphy and SHRIMP U–Pb dating of the Surprise Creek Formation, Torpedo Creek and Warrina Park Quartzites, Mt Isa Inlier

Autor: PR Blake, Lance P. Black, PN Southgate, M. J. Jackson, J. Domagala

Publikováno v: Australian Journal of Earth Sciences. 52:1-25

In the western part of the Mt Isa Inlier one of the most obvious lithostratigraphic correlations is the Torpedo Creek Quartzite (Lawn Hill Platform) and the Warrina Park Quartzite (Leichhardt River Fault Trough). These two sand bodies form the basal

SHRIMP U-Pb detrital zircon ages from Proterozoic and Early Palaeozoic sandstones and their bearing on the early geological evolution of Tasmania

Autor: Lance P. Black, Clive R. Calver, David B. Seymour, A. R. Reed

Publikováno v: Australian Journal of Earth Sciences. 51:885-900

Detrital zircons from 13 Late Mesoproterozoic to Early Neoproterozoic sandstones and two Palaeozoic sandstones from Tasmania were dated in order to improve constraints on depositional ages, to test correlation between Proterozoic inliers, and to char
