In this paper, 5 palynological assemblages are recognized as follows: Quercoidites-Ephedripites-Meliaceoidites from the upper Lulehe Formation belongs Early Eocene; Quercoidites-Piceaepollenites-Meliaceoidites from the bottom of Lower Ganchaigou Formation belongs to Middle Eocene; Ephedripites-Qinghaipollis-Nitrariadites from the middle of Lower Ganchaigou Formation belongs to Later Eocene-Early Oligocene; Ephedripites-Chenopodipollis-Nitrariadites from the bottom of Upper Ganchaigou Formation belongs to Middle Oligocene; Betulaepollenites-Ephedripites-Pinus from the top of Upper Ganchaigou Formation belongs to Late Oligocene. Palynological assemblage from Tarim Basin, Qaidam Basin and Xining-Minhe Basin can be well compared.
