“…This indicates that the end-Permian mass extinction in Australia is essentially the same age in both terrestrial and marine sequences of high-latitude Gondwana and in low-latitude northern hemisphere marine and terrestrial sequences (Metcalfe et al, 2008;Shen et al, 2011). There appears to be little support for a diachronous end-Permian mass extinction (e.g.…”

“…In Eastern Australia the δ 13 Cisotope negative excursion occurs in the basal part of the Rewan Group in the Bowen Basin and within the Protohaploxypinus microcorpus palynology zone (Morante 1995) (Fig. 16) interpreted to be of late Changhsingian age (Metcalfe et al, 2008). In the Sydney Basin, the δ 13 C-isotope negative excursion occurs at the top of the Newcastle Coal Measures in the northern Sydney Basin (Morante, 1996) and in the lower Wombarra Claystone 1 m above the top of the Bulli Coal in the southern Sydney Basin (Williams et al, 2012; Fig.…”

“…Although several significant stratigraphical gaps are apparent in the Lopingian successions of the Western Australian basins (Gorter and Davis, 1999), several basins do appear to host sediments spanning the crucial terminal phase of the Changhsingian and the Permian-Triassic boundary, marked notably by the deposition of the Kockatea (northern Perth Basin), Locker (Carnarvon Basin) and Blina (Canning Basin) shales, all of which extend from latest Changhsingian well through the Early Triassic (Thomas et al, 2004;Metcalfe et al, 2008). Lopingian intercalated continental and marine sandstones, mudstones and minor coals and limestones are preserved in offshore parts of the Canning and Bonaparte basins of northwestern Australia (Mory, 1988).…”

This paper presents an overview of the space and time distributions of Lopingian strata and biotas in Australia, New Zealand, Timor and New Caledonia. Based on this review, we propose a new schematic Late Permian (Lopingian) regional palaeogeographical reconstruction and marine palaeobiogeographical synthesis. The latter also incorporates some key features of the ocean circulation patterns around southeastern Gondwana, inferred primarily from the distribution of regional marine Lopingian faunas.Across Australasia, Lopingian successions accumulated in a wide range of tectonic, palaeoenvironmental and palaeolatitudinal settings. In New Zealand, Lopingian strata are found in several tectonostratigraphical terranes, notably the Brook Street, Dun Mountain–Maitai, Caples, Waipapa and Torlesse terranes/superterranes, each originating as a distinctive basin, island arc or ocean ridge. For the most part, these successions represent displaced segments of volcanic arcs, arc‐flanking clastic aprons, intra‐ and fore‐arc basins and accretionary complexes, some of which have been traced via stratigraphical, biostratigraphical and petrological correlations into New Caledonia and eastern Australia. This spectrum of Lopingian tectono‐sedimentary environments in New Zealand is interpreted to have been originally located near northeastern Australia on a convergent continental margin (i.e. the Panthalassan margin of southeastern Gondwana). Brachiopod and bivalve faunas occur widely throughout the Lopingian successions of New Zealand and have been closely studied. A total of five successive faunal zones are recognized, ranging in age from mid‐late Wuchiapingian to the end of the Changhsingian.In Australia, Lopingian deposits are dominated by non‐marine successions in a large number of widely distributed sedimentary basins; onshore exposures of marine deposits are known only from the Gympie Terrane in eastern Australia and the Canning and Bonaparte basins in Western Australia. Lopingian terrestrial sediments are most extensively represented in eastern Australia within a major meridional foreland basin complex (the Tasmania, Sydney, Gunnedah and Bowen basins), for which the evolution through the Lopingian and Early Triassic was governed by the dynamics of the New England Orogen along the Panthalassan margin of southeastern Gondwana. Most of the non‐marine successions in eastern Australia are rich in coal measures and plant fossils and locally contain well‐preserved non‐marine invertebrate and vertebrate fossils. A succession of six palynostratigraphical zones has been recognized in eastern Australia spanning the Lopingian through the Early Triassic. Several of these palynozones have also been recognized in Western Australia, allowing the discrimination and correlation of Lopingian deposits in both onshore and offshore successions. In contrast to eastern Australia and New Zealand, the marine Lopingian successions of Western Australia and Timor are dominated by carbonates that are only locally interbedded with siliciclastic sediments and sparse volcaniclastics; these successions accumulated in a giant sedimentary basin located on a passive and actively rifting continental margin. Marine connections and free and frequent biotic interchanges between this Western Australian superbasin (including Timor) and the Himalayan region of Nepal, southern Tibet and northern India throughout the Lopingian are evident from the shared occurrences of many shallow‐marine invertebrate species.

High‐resolution Lopingian (Late Permian) timescale of South China

et al. 2010

The Lopingian represents the last epoch of the Palaeozoic Era and is bracketed by two severe biotic mass extinctions associated with dramatic environmental changes. The Lopingian Epoch lasted about 7 millions years and was also bracketed by large volcanic eruptions with the Emeishan volcanics at the base and the Siberian traps at the top. Considerable data have accumulated recently and in this paper we attempt to summarize these findings in a high-resolution Lopingian (Late Permian) timescale that integrates currently available multiple biostratigraphic, isotope chemostratigraphic, geochronologic and magnetostratigraphic data. In South China at least 13 conodont zones, multiple polarity zones and large carbon isotope fluctuations in the Lopingian are recognized and provide the high-resolution calibration that is essential to study this Late Permian interval characterized by Earth's largest biotic extinction. We also present a global correlation chart for the marine Lopingian Series.
