| 摘 要： | Most geologists believe that there are no Early and Middle Triassic strata in the W. Gandisê stratigraphic subregion, but the present authors have found Early Triassic conodonts for the first time in the Shiquanhe area, including five conodonts genera (Form genera): Pachycladina, Neohindeodella, Cornudina, Hadrodontina and Hibbardella sp. etc. Then we affirm that Early Triassic deposits exist in the Gandisê stratigraphic subregion, and establish the Tangnale Formation. The conclusion is new important complementary basal data for Triassic stratigraphy division of Gangdisê, reconstructing palaogeography and studying Gangdisê from Paleozoic to Mesozoic island-arc evolution and transi-tion.

| Abstract: | Most geologists believe that there are no Early and Middle Triassic strata in the W. Gandisê stratigraphic subregion, but
the present authors have found Early Triassic conodonts for the first time in the Shiquanhe area, including five conodonts
genera (Form genera): Pachycladina, Neohindeodella, Cornudina, Hadrodontina and Hibbardella sp. etc. Then we affirm that Early Triassic deposits exist in the Gandisê stratigraphic subregion, and establish the Tangnale
Formation. The conclusion is new important complementary basal data for Triassic stratigraphy division of Gangdisê, reconstructing
palaogeography and studying Gangdisê from Paleozoic to Mesozoic island-arc evolution and transition.
