The provenance and paleogeography of the Upper Triassic deep-sea flysch Langjiexue Croup (LG) of the Shannan Terrane in the northeastern Himalaya orogen, south of Yarlung Zangbo, have been disputed in recent years since
its affinity to the Tethys Himalaya was suspected during the early 2000s. Based on the earlier discoveries of the Upper Permian-Triassic basalts and mafic dykes from the LG and of coeval detrital zircons from the Qulonggongba Formation
(QF) in shallow shelf sediments of the Tethys Himalaya, the previous viewpoints on the basin and tectonics of the LG have been recently tejected. We compared the tu'o units of the Upper Triassic, and our results reveal a number of differences, discrepancies, and inconsistencies in the debate, raising crucial questions on the postulation and provenance model of the remote Gondwanide Orogen for the LG. It is suggested that more observations and evideine are needed to further improve the paleogeographic understanding and relationship ofthe two units.
