The Palaeozoic tectono-metallogenic evolution of the northern Tasman Fold Belt System, Australia: Interplay of subduction rollback and accretion

Temporal correlation of magmatic-tectonic events in the lower and upper crust in north-east Australia

“…The 86 Kr peak was measured as a gas blank and was subtracted from the 86 Sr signal. Replicate analyses of the international standards BHVO-2 and SRM 987 are given in Black and McChulloch (1990) 420 Ma granitoids SHRIMP U-Pb Black and McChulloch (1990) 260-280 Ma S-and Itype granitoids SHRIMP U-Pb zircon dating by Davies et al (2002) whole-rock Sm-Nd and Rb-Sr ages by Champion and Chappell (1992) 300-320 Ma I-type granitoids whole-rock Sm-Nd and Rb-Sr by Champion and Chappell (1992) (Bruce and Niu 2000) and formation of microcontinents (Fergusson et al 2001) Back-arc extension mantle upwelling preceded Siluro-Devonian magmatism (Vos et al 2007) Back-arc extension mantle upwelling basaltic magma underplating preceded Carboniferous and Permian magmatism, which occured during compression, arc accretion and basin closure (Vos et al 2007) Back-arc extension, mantle upwelling, and basaltic magma underplating preceded Carboniferous and Permian magmatism, which occured during compression, arc accretion and basin closure (Vos et al 2007) Archaean and Proterozoic plume and/or plate margin activity (Betts et al 2010) 900-1300 Ma Rodinia supercontinen amalgamatioñ 740-825 Ma Rodinia supercontinen break-up (Li et al 2008 Murgulov et al (2007Murgulov et al ( , 2009. BKD is the Black Cap Diorite and LG is the Lochaber Granitoid collectors in static mode, and the signal for each mass was recorded as a function of time.…”

“…It was most likely associated with intrusion of basaltic magma around the crust-mantle boundary in response to back-arc basin extension and mantle upwelling (Vos et al 2007) in the Georgetown Inlier and Broken River Province from 530 to 470 Ma (Kositcin et al 2009). Zircon Hf-isotope data indicate that these *420 Ma granitoids were produced by remelting of heterogeneous Mesoproterozoic to Archaean crust.…”

“…However, this is not required; modelling of the zircon data simply suggests remelting of the heterogeneous *1,550 Ma crust. Basin closure and arc accretion (Vos et al 2007) were associated with crustal reworking followed by juvenile addition prior to the *340 Ma magmatic events (Champion and Chappell 1992) on both sides of the Palmerville Fault (Fig. 1).…”

Numerical models of slab migration in continental collision zones

“…Ranalli et al, 2000;Regard et al, 2003;Toussaint et al, 2004); (2) part of the continental buoyant crust is delaminated from the lithospheric mantle and accreted onto the overriding plate, allowing continuation of plate convergence (delamination) (e.g. Cloos, 1993;Chemenda et al, 1996;Kerr and Tarney, 2005;Vos et al, 2007) or (3) the slab breaks off as a consequence of tensile stress from the pull of the sinking oceanic lithosphere in the mantle connected to the continental part of the plate (e.g. Wortel and Spakman, 1992;Davies and von Blanckenburg, 1995;Wong-A-Ton and Wortel, 1997;Duretz et al, 2011;van Hunen and Allen, 2011).…”

Onland signatures of the Palawan microcontinental block and Philippine mobile belt collision and crustal growth process: A review

“…Such recognition provides crucial information for further understanding the geological features observed not only in the Philippines, but in other areas of arc-continent collision (e.g. Aitchison et al, 1995;Huang et al, 1995;Byrne and Liu, 2002;Brown et al, 2006;Vos et al, 2007).…”
