| Abstract: | The Upper Cretaceous Bolinxiala Formation,named by Guo Tie-ying et al.(1991) based on a type section at Bolin of Zanda,southwestern Tibet,mainly consists of marls and limestones.The basal Bolinxiala Formation consists of glauconitic limestones and conformably overlies the glauconitic quartze sandstones of the upper Gajie Formation.Planktonic foraminiferal fossil assemblages identified from the Bolinxiala Formation at Bolin,Zanda,southwestern Tibet,give an age of latest Albian to Maastrichitan.The fossil contents of the Bolinxiala Formation allow its correlation with successions across a platform-to-basin transect of the Late Cretaceous Tethyan Himalaya passive margin.The new planktic foraminiferal biostratigraphic data indicate that the Bolinxiala Formation in Zanda has a much longer duration than that of the Zongshan Formation.Therefore,the Bolinxiala Formaton should not be substituted by the Zongshan Formation. |
