Prototethyan Accretionary Orogenesis Along the East Gondwana Periphery: New Insights From the Early Paleozoic Igneous and Sedimentary Rocks in the Sibumasu

“…In fact, in the eastern Indochina region of East Gondwana northern margin, Wang et al (2020aWang et al ( , 2020bWang et al ( , 2020c revealed a northerly younging early middle Paleozoic (∼485-410 Ma with the majority at ∼460-430 Ma) igneous event related to convergent plate margin activity (Figures 3b and 3d). This igneous activity was accompanied by the ∼450-424 Ma metamorphism and regional unconformities among the late Cambrian and latest Silurian/earliest Devonian strata, along with coeval with deep-water turbidities and radiolarian-bearing chert (e.g., Maluski et al, 2005;Nakano et al, 2007;Nam et al, 2003;H.…”

“…Sr-Nd isotopic data for the Mandi mafic rocks and Greater Himalayan granite, Gangdese I-type granite, Lincang-Inthanon granite, Lachlan I-and S-type granites and Ordovician sedimentary rocks, South China early Paleozoic granite, and eastern Indochina early Paleozoic mafic rocks are from Robinson et al (2001), Miller et al (2001, Imayama and Arita (2008), Zhu et al (2012), and Wang et al ( , 2020aWang et al ( , 2020bWang et al ( , 2020c and references therein. Pb isotopic data for Tethyan Ocean, Indian oceanic turbidites and eastern Indochina early Paleozoic mafic rocks are from Petford andAtherton (1996), Miller et al (2001), Hou et al (2003), Wang et al (2008Wang et al ( , 2020aWang et al ( , 2020bWang et al ( , 2020c. DMM, OIB, NHRL, EMI, EMII, Altantic-Pacific Ocean MORB, Indian Ocean MORB and NCC are from Kay (1978), Hart (1984Hart ( , 1988, Zindle and Hart (1986), Hou et al (2003), andWang et al (2008).…”

“…A northerly propagating accretionary orogen, from ∼485 Ma in the Kontum to ∼430 Ma in the northern Truong Son zone, was proposed in response to the closure of the early Paleozoic Tam Ky-Phuoc Son Ocean (likely equivalent to the Yunxian-Menghai Ocean) and subsequent assemblage (e.g. Wang et al, 2020aWang et al, , 2020bWang et al, , 2020c. As a result, the early Paleozoic Yunxian-Menghai Ocean in the SW Yunnan and SE Asia portions of the Sibumasu is compatible with the Tam Ky-Phuoc Son Ocean in the eastern Indochina, corresponding to two segments of the Prototethyan Ocean.…”
