The mid-Cretaceous Langshan Formation, which crops out on the north Lhasa subterrane, central Tibet, is composed of a thick carbonate sequence with local volcanic rock and sandstone interlayers. In this study, we present data from the Asuo area, including fossil assemblages within carbonates, detrital zircon U–Pb ages of sandstone interlayers, zirc...
Due to the unclear tectonic setting of the Jurassic ophiolites within the Bangong-Nujiang suture, how and when intra-oceanic subduction initiated within the Bangong Meso-Tethys remain controversial. Based on the new petrological, geochemical, and geochronological data reported in this paper, ∼190–180 Ma MORB-like ophiolites and OIB-like mafic rocks...
As a part of the Bangong-Nujiang suture, the Shiquanhe-Namco ophiolite mélange belt (SNM), together with the Bangong-Nujiang ophiolite mélange belt (BNM), records the evolutionary history of the Mesotethys. In terms of the closure of the Mesotethys, previous sedimentological research has focused on the BNM, while the SNM remains insufficient. On th...
Although voluminous Jurassic ophiolites have been reported along the Bangong–Nujiang Suture Zone (BNSZ), the tectonic setting of ophiolites and the Jurassic evolution history of the Meso-Tethys Ocean remain mysterious. This study presents petrological, geochronological and geochemical data for newly discovered Jurassic ophiolitic complex in the Asa...
Turbidites from the Shiquanhe–Namco Ophiolite Mélange Zone (SNMZ) record critical information about the tectonic affinity of the SNMZ and the evolutionary history of the Meso-Tethys Ocean in Tibet. This paper reports sedimentologic, sandstone petrographic, zircon U-Pb geochronologic, and clastic rocks geochemical data of newly identified turbidites...

... Its evolution, from north to south, is primarily recorded in the rock strata of Turkey, the Levant, Arabia, Oman, India, Mozambique, Madagascar, Sri Lanka, and East Antarctica (e.g., Meert, 2003;Jacobs and Thomas, 2004;Bybee et al., 2010;de Wall et al., 2012;Fritz et al., 2013;Santosh et al., 2017;Mole et al., 2018;Collins et al., 2021;Baba et al., 2022 and references therein). Recently, some scholars discovered rocks providing evidence of the Neoproterozoic oceanic crustal rocks in the central and southern parts of Tibet, suggesting that they may represent the remnants of the Mozambique Ocean (Zhang et al., 2014aHu et al., 2016Hu et al., , 2018aZeng et al., 2018a;Zhang et al., 2021;Yu et al., 2023 and references therein). Insights into these Neoproterozoic magmatic rocks can give us an opportunity to explore the Precambrian evolution of Tibetan Plateau and the north range of Mozambique Ocean. ...

... This suture was formed during the Late Triassic in response to subduction of the Paleo-Tethyan oceanic plate and the ensuing continental collision event (Wu et al., , 2024. The Shiquan River-Nam Tso Mélange Zone (SNMZ) to the south of the BNSZ separates the Northern Lhasa Block from the Lhasa Block and is composed predominantly of Jurassic supra-subduction zone (SSZ) ophiolites (Qian et al., 2020;Zhang et al., 2020;Li and Wang, 2022;Zeng et al., 2022). Early Jurassic SSZ-type ophiolites have been identified within the BNSZ and SNMZ and compositionally resemble the geological record of subduction initiation in the Izu-Bonin-Mariana arc (Qian et al., 2020). ...
... More recently, provenance analysis of peripheral foreland basins has developed, shedding new light on the understanding of the region (Fan et al., 2015;Chen et al., 2020;Peng et al., 2020a;Luo et al., 2021;Hu et al., 2022;Lai et al., 2022;Zhu et al., 2022). Moreover, the majority of the research has been conducted in the western section (Bangong Co-Amdo) of the Bangong-Nujiang Suture Zone and on its northern side (Sun et al., 2019;Li et al., 2019bLi et al., , 2020Fan et al., 2021;Xiao et al., 2022;Zeng et al., 2022;Zhu et al., 2022;Wang et al., 2024), while the eastern section (Amdo-Basu) remains relatively less studied (Li et al., 2017c;Chen et al., 2018Chen et al., , 2020Xu et al., 2020Xu et al., , 2022, making comparisons with the southeastern part in Yunnan difficult (Fig. 1). ...
... The Bangong-Nujiang suture zone, separating the Qiangtang Block to the north from the Lhasa Block to the south, marks the relic of the vanished Neo-Tethys Ocean in central Tibet (Yin and Harrison, 2000), and is characterized by several discontinuous belts of ophiolites (including seamounts, topographic ridges, or oceanic plateaus) scattering in an extensive belt up to 200-300 km wide and ~1700 km long across central Tibet (Fig. 12a; e.g., Zhu et al., 2006;Bao et al., 2007;Zhang et al., 2014a;Hao et al., 2019;Li et al., 2019;Zhang et al., 2019;Tang et al., 2020;Yan and Zhang, 2020;Zhang et al., 2021b). Numerous studies suggested that these ophiolites mainly formed in the Jurassic and had subduction geochemical affinities (e.g., Shi et al., 2008;Liu et al., 2016a;Wang et al., 2016;Huang et al., 2017;Zeng et al., 2021aZeng et al., , 2021b, indicating a Jurassic intra-oceanic subduction system developed within the Neo-Tethys Ocean (e.g., Li et al., 2019;Yan and Zhang, 2020;Hu et al., 2022). ...
