“…Palaeoproterozoic tectonism was dominated by extension, whereas Mesoproterozoic tectonism occurred in two stages between 1330-1280 Ma and 1225-1140 Ma (Clark et al 2000;Kirkland et al 2011;.…”

S U M M A R YGroup and phase velocity maps in the period range 2-20 s for the Proterozoic east AlbanyFraser Orogen, Western Australia, are extracted from ambient seismic noise recorded with the 70-station ALFREX array. This 2 yr temporary installation provided detailed coverage across the orogen and the edge of the Neoarchean Yilgarn Craton, a region where no passive seismic studies of this scale have occurred to date. The surface wave velocities are rather high overall (>3 km s −1 nearly everywhere), as expected for exposed Proterozoic basement rocks. No clear signature of the transition between Yilgarn Craton and Albany-Fraser Orogen is observed, but several strong anomalies corresponding to more local geological features were obtained. A prominent, NE-elongated high-velocity anomaly in the northern part of the array is coincident with a Bouguer gravity high caused by the upper crustal metamorphic rocks of the Fraser Zone. This feature disappears towards longer periods, which hints at an exclusively upper crustal origin for this anomaly. Further east, the limestones of the Cenozoic Eucla Basin are clearly imaged as a pronounced low-velocity zone at short periods, but the prevalence of low velocities to periods of ≥5 s implies that the uppermost basement in this area is likewise slow. At longer periods, slightly above-average surface wave velocities are imaged below the Eucla Basin.

The Antarctic rock record spans some 3.5 billion years of history, and has made important contributions to our understanding of how Earth's continents assemble and disperse through time. Correlations between Antarctica and other southern continents were critical to the concept of Gondwana, the Palaeozoic supercontinent used to support early arguments for continental drift, while evidence for Proterozoic connections between Antarctica and North America led to the 'SWEAT' configuration (linking SW USA to East Antarctica) for an early Neoproterozoic supercontinent known as Rodinia. Antarctica also contains relicts of an older Palaeo-to Mesoproterozoic supercontinent known as Nuna, along with several Archaean fragments that belonged to one or more 'supercratons' in Neoarchaean times. It thus seems likely that Antarctica contains remnants of most, if not all, of Earth's supercontinents, and Antarctic research continues to provide insights into their palaeogeography and geological evolution. One area of research is the latest Neoproterozoic-Mesozoic active margin of Gondwana, preserved in Antarctica as the Ross Orogen and a number of outboard terranes that now form West Antarctica. Major episodes of magmatism, deformation and metamorphism along this palaeo-Pacific margin at 590 -500 and 300-230 Ma can be linked to reduced convergence along the internal collisional orogens that formed Gondwana and Pangaea, respectively; indicating that accretionary systems are sensitive to changes in the global plate tectonic budget. Other research has focused on Grenville-age (c. 1.0 Ga) and PanAfrican (c. 0.5 Ga) metamorphism in the East Antarctic Craton. These global-scale events record the amalgamation of Rodinia and Gondwana, respectively. Three coastal segments of Grenville-age metamorphism in the Indian Ocean sector of Antarctica are each linked to the c. 1.0 Ga collision between older cratons but are separated by two regions of pervasive Pan-African metamorphism ascribed to Neoproterozoic ocean closure. The tectonic setting of these events is poorly constrained given the sparse exposure, deep erosion level and likelihood that younger metamorphic events have reactivated older structures. The projection of these orogens under the ice is also controversial, but it is likely that at least one of the Pan-African orogens links up with the Shackleton Range on the palaeo-Pacific margin of the craton. Sedimentary detritus and glacial erratics at the edge of the ice sheet provide evidence for the c.

“…Growing interest is also being paid to U-Pb chronology of detrital rutile as a provenance indicator (Allen and Campbell, 2007;Birch et al, 2007;Rösel et al, 2011;Meinhold et al, 2011;Okay et al, 2011). While U-Pb chronology of rutile by ID-TIMS is a well established technique and allows high precision ratios to be measured (e.g., Ludwig and Cooper, 1984;Schärer et al, 1986;Corfu and Andrews, 1986;Mezger et al, 1989;Davis, 1997;Cox et al, 2002;Treloar et al, 2003;Schmitz and Bowring, 2003), rutile can also be dated by microprobe (secondary ion mass spectrometry -SIMS, LA-ICP-MS) techniques (Sircombe, 1995;Clark et al, 2000;Vry and Baker, 2006;Harrison et al, 2007;Storey et al, 2007;Kooijman et al, 2010;Meinhold et al, 2011;Schmitt and Zack, 2012;Taylor et al, 2012).…”

“…Alternatively, making use of the observation that rutiles contain very low Th (hence negligible radiogenic 208 Pb from 232 Th decay), the measured isotopic ratios can be corrected for common Pb by measuring 208 Pb and assuming it is virtually entirely common Pb (Clark et al, 2000;Allen and Campbell, 2007;Kooijman et al, 2010;. Currently, strategies are not available for handling reference material data with variable common-Pb to determine normalisation factors for LA U-Pb dating.…”

In response to the general lack of sufficiently abundant and high quality rutile U-Pb reference materials for in situ geochronology, we have characterised two new potential rutile ~ 1.8 Ga reference materials (Sugluk-4 and PCA-S207) from granulite facies belts of the Canadian Shield, namely the northern Cape Smith Belt of Quebec and the Snowbird Tectonic Zone (Sasatchewan). Characterisation includes ID-TIMS and LA-ICP-MS U-Pb dating, imaging, and trace element analysis. We compare these materials with existing rutiles used already (R19 and R10;Luvizotto et al., 2009;
