摘要：
Based on the data of palynology from the Dahonggou Section, Daqaidam area in northeast marginal Qaidam basin. 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 the Tarim basin, Qaidam basin and Xining-Minhe basin can be well compared.
