For further information contact the UOW Library: [email protected] Early Palaeozoic continental growth in the Tasmanides of northeast Gondwana and its implications for Rodinia assembly and rifting Abstract Gondwana formed in the Neoproterozoic to Cambrian mainly from collision along the East African and Kuunga orogens at about the same time that the Gondwana palaeo-Pacific facing margin became a long-lived active margin and formed the Terra Australis Orogen. This orogen, and in particular the Tasman Orogenic Belt (the Tasmanides) sector of eastern Australia, is distinguished by widespread shortening of quartz turbidite successions and underlying oceanic basement, with less abundant island arc assemblages. Early Palaeozoic accretionary development of the Tasmanides followed Rodinia breakup at 800-750 Ma to form the palaeo-Pacific cO ean. In eastern Australia, a second rifting episode at 600-580 Ma is more widely developed with siliciclastic sedimentation and rift-related igneous activity. In parts of the Delamerian Orogen of South Australia and northwestern New South Wales and in the exposed northern Thomson Orogen of north and central Queensland, the rift-related sedimentary successions have a dominant 1.3 to 1 Ga detrital zircon age signature implying local sources. -
Geological and Geophysical Studies in the Amadeus Basin, Central Australia

Lambeckl Teleseismictravel-times recorded acrossthe central Australian basins and Musgrave and Arunta Blocks impose signifrcant constraints on crustal and upper mantle structure. Major discontinuities in lateral structure are required, particularly acrossthe Redbank-Ormiston Thrusts in the Arunta Block and the Woodroffe-Mann Thrusts in the Musgrave Block. The deep structure of these tectonic units exhibit considerablesimilarity, and in both instances the thrusts dip at about 45" through to the Moho. Major offsets in Moho depth are produced which have persisted since the time of the last movements on the faults, about 300 Ma ago in the case of the Redbank Thrust and much earlier in the case of the Woodroffe-Mann Thrusts. The teleseismic models are consistent with deep crustal seismic reflection observations across the Redbank Thrust Zone, and they confirm the conclusion drawn from gravity studies that the region as a whole is not in local isostatic equilibrium and that maximum stress- differenceswithin the crust and upper mantle are of the order of 100MPa.

GOTHIAM California. The truncation of these 1.8–1.0 Ga orogenic belts in southwest- ern and northeastern Laurentia suggests KETILIDEAN that they once extended farther. We propose that Australia contains the con- tinuation of these belts to the southwest LABRADORIAN and that Baltica was the continuation to the northeast.

1 SUPPLEMENTARY INFORMATION to Copper and Its Isotopes in Organic-Rich Sediments: from the Modern Peru Margin to Archean Shales
SUPPLEMENTARY INFORMATION TO Copper and its isotopes in organic-rich sediments: from the modern Peru Margin to Archean shales S1. Peru Margin sample location and details The Peru margin, along with the Chilean margin, is considered as the most productive up- welling system in the world ocean [S1], driven mainly by the southeast trade winds [S2]. The hydrography is dominated by the Peru Current, with the poleward Peruvian Undercurrent and the equatorward Chile-Peru Deep Coastal Current being the main coastal currents [S3-S4, and references therein]. The upwelling-fed high productivity of this region results in the permanent eastern South Pacific oxygen minimum zone (OMZ), with its core located between 5 and 13°S. At these latitudes the OMZ reaches its maximal vertical thickness of about 600 m, with an upper boundary at ≤ 100 m water depth [S1]. The vertical thickness of the OMZ and the location of its upper boundary, however, fluctuate with the El Niño Southern Oscillation (ENSO) cycle, as well as with the variable influence of the southeast trade winds and northerly winds off the coasts of Peru and Chile [S1]. The seafloor below the OMZ and along the margin is dominated by two main sedimentary facies: (i) a lens-shaped, up to 100m thick, diatomaceous (up to ∼16wt.% opal), organic-rich mud at depths between 50 and 500m at 11-14°S; and (ii) a coarser-grained, less organic-rich, calcareous mud on the shallow shelf at 8.5°S and 15-17°S [S5]. Thus, the most organic-rich sediments are deposited between 11 and 14° S, which are the latitudes targeted here. -

Thrust fault systems typically distribute shear 1 Introduction strain preferentially into the hanging wall rather than the footwall. The Woodroffe Thrust in the Musgrave Block of Continental fault and shear zone systems (e.g. Ramsay, 1980) central Australia is a regional-scale example that does not fit with displacements on the order of several tens to hundreds this model. It developed due to intracontinental shortening of kilometres generally show an asymmetric mylonite distri- during the Petermann Orogeny (ca. 560–520 Ma) and is inter- bution across the main fault horizon that is opposite for re- preted to be at least 600 km long in its E–W strike direction, verse faults or thrusts and normal faults or detachments. Fault with an approximate top-to-north minimum displacement of zones are predicted to become more viscous and broaden 60–100 km. -

D. EVANS Department of Geology & Geophysics, Yale University, New Haven, CT 06520-8109, USA (e-mail: [email protected]) Abstract: Palaeomagnetic apparent polar wander (APW) paths from the world’s cratons at 1300–700 Ma can constrain the palaeogeographic possibilities for a long-lived and all-inclusive Rodinia supercontinent. Laurentia’s APW path is the most complete and forms the basis for super- position by other cratons’ APW paths to identify possible durations of those cratons’ inclusion in Rodinia, and also to generate reconstructions that are constrained both in latitude and longitude relative to Laurentia. Baltica reconstructs adjacent to the SE margin of Greenland, in a standard and geographically ‘upright’ position, between c. 1050 and 600 Ma. Australia reconstructs adja- cent to the pre-Caspian margin of Baltica, geographically ‘inverted’ such that cratonic portions of Queensland are juxtaposed with that margin via collision at c. 1100 Ma. Arctic North America reconstructs opposite to the CONgo þ Sa˜o Francisco craton at its DAmaride–Lufilian margin (the ‘ANACONDA’ fit) throughout the interval 1235–755 Ma according to palaeomag- netic poles of those ages from both cratons, and the reconstruction was probably established during the c. -
Geomorphology of the Acraman Impact Structure, Gawler Ranges, South Australia
Cadernos Lab. Xeolóxico de Laxe Coruña. 2010. Vol. 35, pp. 209 - 220 ISSN: 0213-4497 Geomorphology of the Acraman impact structure, Gawler Ranges, South Australia WILLIAMS, G.E.1 and GOSTIN, V.A. 1 (1) Discipline of Geology and Geophysics, School of Earth and Environmental Sciences, University of Adelaide, SA 5005, Australia Abstract The late Neoproterozoic Acraman impact structure occurs mostly in felsic volcanic rocks (Mesoproterozoic Gawler Range Volcanics) in the Gawler Ranges, South Australia, and strongly influences the topography of the region. The structure is expressed topographically by three main features: a near-circular, 30 km diameter low-lying area (Acraman Depression) that includes the eccentrically placed Lake Acraman playa; a partly fault-controlled arcuate valley (Yardea Corridor) at 85–90 km diameter; and arcuate features at 150 km diameter that are visible on satellite images. Geological and geomorphological observations and apatite fission-track data indicate that Acraman is eroded several kilometres below the crater floor, with the structure originally comprising a transient cavity about 40 km in diameter and a final structural rim 85–90 km in diameter. Ejecta of shock- deformed fragments of felsic volcanic rock up to 20 cm across derived from the Acraman impact form an extensive horizon ≤40 cm thick in Ediacaran (about 580 Ma) shale in the Adelaide Geosyncline 240–370 km to the east of the impact site. A correlative band ≤7 mm thick of sand-sized ejecta occurs in mudstone in the Officer Basin up to 540 km to the northwest of Acraman. The dimensions of the impact structure and the geochemistry of the ejecta horizon imply that the bolide was a chondritic asteroid >4 km in diameter. -
