Notes:
The newly discovered marine horizon at Zhepure Syncline, north of Qomolangma, revises timing of the closure of the eastern Neo-Tethys seaway in the central Himalayas. The marine Pengqu Formation conformably overlies a Lutetian shallow-water carbonate platform and comprises shales interbedded with sandstones deposited in a neritic shelf environment. The strata are dated by nannofossils and foraminifera as late early Lutetian to late Priabonian age (NP15–NP20, deposited ≈ 47–34 Ma), indicating that the final closure of the Tethys seaway in this region occurred at ∼ 34 Ma. The newly discovered strata provide evidence about emplacement of a major thrust sheet south of southern Tibet prior to ∼ 37 Ma, which affected the regional climate.
