U-Pb dating and tectonic implication of ophiolite and metabasite from the Song Ma suture zone, northern Vietnam

The volcaniclastic series from the Luang Prabang Basin, Laos: A witness of a triassic magmatic arc?

“…As for the Ailaoshan Suture, these rocks are Devonian to Carboniferous in age (e.g., Trung et al, 2006;Vuong et al, 2013;Zhang R.Y. et al, 2013Zhang R.Y. et al, , 2014.…”

When Did the Paleotethys Ailaoshan Ocean Close: New Insights From Detrital Zircon U‐Pb age and Hf Isotopes

“…The superimposing structures have hampered previous tectonic reconstruction attempts of the Ailaoshan Ocean, especially on the question of when the ocean eventually closed. Previous proposals about the closure time vary greatly from the Devonian‐Permian (Gatinsky, ; Gatinsky & Hutchison, ) to Triassic (Huang & Opdyke, ; Jian et al, ; C. Liu, Deng, et al, ; Liu, Tang, et al, ; Nakano et al, , ; Wang & Metcalfe, ; F. Zhang et al, ; R. Y. Zhang, Lo, et al, ). Diachronous closure from the Permian to Triassic was also proposed (Cai & Zhang, ; Lai, ; J. Liu et al, ).…”

Geochronology and petrogenesis of Middle Permian S-type granitoid in southeastern Guangxi Province, South China: Implications for closure of the eastern Paleo-Tethys

“…14d) (Jian et al, 2009b;Chen et al, 2011a;Liu et al, 2012;Zi et al, 2012bZi et al, , 2013Wen et al, 2013;Lai et al, 2014b;Zhang et al, 2014). Closure of the Paleo-Tethys led to collision between the ICB and SCB in the Middle Triassic (~230 Ma) (Wan, 2011;Liu et al, 2012;Zi et al, 2012bZi et al, , 2013Wang et al, 2013a;Zhang et al, 2014), resulting in the development of NW/WNWtrending structures Wang et al, 2013a) and S-type granites at~230 Ma (Deng et al, 2004;Zhao et al, 2010;Chen et al, 2011b) in SE Guangxi region.…”

“…Vuong et al (2013) also reported Sm/Nd isochron ages for the Song Ma ophiolite at 387 ± 56-313 ± 32 Ma. However, Zhang et al (2014) obtained SIMS zircon U-Pb ages for the Song Ma ophiolite at 340 ± 29-315 ± 4 Ma and Lai et al (2014b) obtained UPb zircon ages for the Ailaoshan ophiolite in the range of 365 ± 7 to 334 ± 6 Ma. Ages of ophiolites in the Jinshangjiang, Ailaoshan and Song Ma suture zones are coeval with U-Pb and Sm-Nd ages of the Bangxi-Chenxing ophiolite (ESM Table 1 and Fig.…”

“…Geochemistry and tectonic settings of ophiolites, arc-/ collision-related granitoids and volcanic rocks widely distributed along this zone have been studied by various workers (e.g. Lepvrier et al, 2008;Jian et al, 2009aJian et al, , 2009bFan et al, 2010;Liu et al, 2012;Zi et al, 2012aZi et al, , 2012bZi et al, , 2013Liu et al, 2013;Vuong et al, 2013;Wu et al, 2013;Yang et al, , 2014Lai et al, 2014aLai et al, , 2014bZhang et al, 2014). A general consensus of these studies is that the opening of the Paleo-Tethys started during Late Devonian-Early Carboniferous (Jian et al, 2009b;Vuong et al, 2013;Lai et al, 2014b;Zhang et al, 2014), with subduction initiation during the Middle Permian and initial collision and amalgamation probably during Early-Middle Triassic Zi et al, 2012aZi et al, , 2012bZi et al, , 2013Liu et al, 2013;Wu et al, 2013;Zhang et al, 2014).…”
