Nujiang Canyon ophiolites(eastern Tibetan Plateau): Records of early Jurassic subduction initiation at passive continental margin of the Lhasa block?
《Science China Earth Sciences》2025年第3期730-749,共20页Qing QIAN Baolu SUN Feiyu DONG 
supported by the National Natural Science Foundation of China (Grant Nos. 42072076, 42472070 & 41472058);the Second Tibetan Plateau Scientific Expedition and Research Program (STEP) (Grant No. 2019QZKK0801)。
The formation ages and genesis of the Nujiang Canyon ophiolites in the eastern Tibetan Plateau are still unclear, and it has been debated whether they belong to the Neo-Tethyan or Paleo-Tethyan suture zones. This stud...
