Devonian to Permian plate tectonic cycle of the Paleo-Tethys Orogen in southwest China (I): Geochemistry of ophiolites, arc/back-arc assemblages and within-plate igneous rocks

Triassic high-strain shear zones in Hainan Island (South China) and their implications on the amalgamation of the Indochina and South China Blocks: Kinematic and 40Ar/39Ar geochronological constraints

“…As a result, the data mentioned earlier appear to indicate that, during late Paleozoic, the Bangxi-Chengxin ophiolitic zone in Hainan probably extended westerly to join the synchronous Song Ma-Ailaoshan tectonic zone, constituting an east-westerly convergent boundary between the Indochina and South China Blocks in spite that the tectonic nature of this zone is still unclear during the early Paleozoic ( Fig. 1a; e.g., Zhong, 1998, Jian et al, 1998, 2009aLan et al, 2000;Li et al, 2000;Z.X. Li et al, 2002;Carter et al, 2001;Carter and Clift, 2008).…”

Reconstructing South China in Phanerozoic and Precambrian supercontinents

“…4), the remnants of which are represented by the Changning-Menglian-Inthanon suture in SE Asia (Arboit et al, 2016a;Arboit et al, 2016b;Hara et al, 2012;Kamata et al, 2012;Metcalfe, 2013;. The Jinshajiang-Ailaoshan-Song Ma suture (Jian et al, 2009;Khin et al, 2014;Sone and Metcalfe, 2008), which defines the southeastern margin of the South China Craton (Fig. 2), represents a branch, or back-arc basin, of the Paleo-Tethyan Ocean ( Fig.…”

Mid-Triassic felsic igneous rocks from the southern Lancangjiang Zone, SW China: Petrogenesis and implications for the evolution of Paleo-Tethys

“…1; Metcalfe, 2002Metcalfe, , 2003Metcalfe, , 2006Metcalfe, , 2011Zhong, 1998). Voluminous Triassic igneous rocks crop out discontinuously along the two flanks of the Lancangjiang zone and extend northward into the Tibetan Plateau and southward into Southeast Asia (Jian et al, 2004(Jian et al, , 2008(Jian et al, , 2009aMetcalfe, 2002Metcalfe, , 2003Metcalfe, , 2006Metcalfe, , 2011Mo et al, 1998;Zhong, 1998). They form an elongated Triassic magmatic belt approximately parallel to the Paleo-Tethys sutures (Fig.…”

“…1). It includes high-pressure glaucophane schist, ophiolitic suites, mélange, and ocean island-, ocean ridge-and arc-related igneous rocks, together with some back-arc rock associations Jian et al, 2004Jian et al, , 2008Jian et al, , 2009aMo et al, 1998;YNBGMR, 1990;Zhang et al, 1985Zhang et al, , 1988Zhong, 1998). It is well documented that these remnants of the main Paleo-Tethys oceanic crust extend southward through Thailand to the Malay Peninsula and Sumatra.…”

“…The opening of the Paleo-Tethys Ocean occurred in the Early Devonian as evidenced by the ChangmingMenglian suture belt in the Lancangjiang zone, SW China, the Chiang Mai-Inthanon suture belt in northern Thailand and the Bentong-Raub suture belt in the Malay Peninsula (see Fig. 1; Feng et al, 2005;Jian et al, 2004Jian et al, , 2008Jian et al, , 2009aMetcalfe, 2002Metcalfe, , 2003Metcalfe, , 2006Metcalfe, , 2011Srichan et al, 2009;Zhong, 1998). Nonetheless, knowledge about the syn-to post-collisional history in this region remains limited.…”
