“…The eastern and north-eastern boundary of Sibumasu is formed by sutures that represent the main Palaeo-Tethys ocean. These Palaeo-Tethyan sutures are, from north to south, the Changning-Menglian suture in SW China, the Chiang Mai-Chiang Rai (re-named in Metcalfe et al, 2017) and Chanthaburi sutures in Thailand and the Bentong-Raub Suture in the Malay Peninsula (Figures 2 and 3). The Sibumasu Terrane is the eastern part of the Cimmerian continent of Sengör (1984) and is here regarded as including the Baoshan and Tengchong blocks of western China and extending to the South Qiangtang Block of Tibet.…”

“…Barber et al, 2011;Gardiner et al, 2016), the Chiang Mai suture (Metcalfe, 2002) and the Chiang Mai-Inthanon Suture Zone (Metcalfe, 2013a). Because of the historically varied names applied to this suture zone, and to avoid confusion with the Inthanon fold and thrust belt zone, Metcalfe et al (2017) propose that this suture be named the Chiang Mai-Chiang Rai Suture Zone and this name is adopted here. Suture zone rocks, including elements of the suture thrust westwards and located in the Inthanon Zone, include Mid Ocean Ridge Basalts (MORB), pelagic radiolarian cherts, pelagic limestones, and pelagic mudstones and turbidites that range in age from Middle Devonian to Middle Triassic (Metcalfe, 2013a, Metcalfe et al, 2017; see Figure 15).…”

“…Palaeogeographic reconstructions including Japan have been proposed by various authors (e.g. Maruyama et al 1997, Metcalfe, 2006Oh, 2006;Isozaki et al 2011;Seton et al 2012;Torsvik et al 2012;Cawood et al 2013;Okawa et al 2013;Wright et al 2013;Metcalfe et al 2017;Safonova et al 2017). Isozaki et al (2010aIsozaki et al ( , 2011 suggested that most of the geologic entities of proto-Japan were formed along the South China margin following the break-up of the supercontinent Rodinia, about 750 Ma ago.…”

It is generally accepted that oceanic plate subduction has occurred along the eastern margin of Asia since about 500 Ma ago. Therefore, the Japanese Islands have a >500 Ma history of oceanic plate subduction in their geological records. In this paper, the accretionary history of the Japanese Islands is divided into six main stages based on the mode and nature of tectonic events and the temporal gaps in the development of accretionary processes. In the first stage, oceanic plate subduction and accretion started along the margin of Gondwana. After detachment of the North and South China blocks in Devonian time, accretionary complexes developed along island arcs offshore of the South and North China blocks. After the formation of back arc basins such as the Japan Sea, accretionary processes occurred only along the limited convergent margin, e.g. Nankai Trough. Detrital zircons of sandstones revealed the accretionary history of Japan. An evaluation of a comprehensive dataset on detrital zircon populations shows that the observed temporal gaps in the development of the Japanese accretionary complexes were closely related to the intensity of igneous activity in their provenance regions. Age distributions of detrital zircons in the accretionary complexes of Japan change before and after the Middle Triassic period, when the collision of the South and North China blocks occurred.

“…Mesogondolella monstra has a relatively wide distribution, including, at least, the Urals (Chernykh, 2005;2006), Nevada (Chernykh et al, 2016), Central Iran (Balini et al, 2015) and Thailand (as M. cf. monstra) (Metcalfe et al, 2017), and is a deep-water species that can provide correlation between the Paleotethys and western North America. Material is from the unpublished MSc thesis of Elinda Dehari at the University of Calgary.…”

The Sakmarian Stage represents a critical time interval because the Late Paleozoic Ice Age reached its acme during this time. After extensive studies, we herein use the First Appearance Datum (FAD) of the conodont Mesogondolella monstra within the lineage from M. uralensis→M. mons-tra→M. manifesta at Bed 26/3 of the Usolka section in the southern Urals, Russia, as the primary signal for the base-Sakmarian GSSP. The first occurrence of the conodont Sweetognathus binodosus within the lineage from Sw. aff. merrilli→Sw. binodosus is used as an auxiliary marker for the base of the Sakmarian Stage. An extrapolated age for this GSSP is 293.52 ± 0.17 Ma produced by a Monte Carlo simulation based on two ash beds dated by chemical abrasion isotope dilution thermal ionization mass spectrometry (CA-ID-TIMS). The 87 Sr/ 86 Sr isotopic value based on conodont apatite for the base of the Sakmarian Stage is approximately 0.70787. Two minor negative excursions in δ 13 C carb are present at the boundary levels and the upper one is consistent with the GSSP level. The documentation of fusulinaceans, ammonoids, brachiopods and palynology also aid intercontinental and marine-terrestrial correlation. The Usolka section meets the requirements for the GSSP and a monument has been established; correlation with sections in North America and South China is also well documented.
