Eocene Palynoflora From Changchang Basin, Hainan Island And Its Bearing On The Implications Of Palaeovegetation And Palaeoclimate

Plants are regarded as good indicators as they are sensitive to climatic and environmental changes. Much environmental information can be obtained from plant mega-fossils, spores and pollen grains and other micro-fossils preserved in the strata when studying the Tertiary climate and environment changes, which is presently an important research area in the global sphere.With the development of many new and novel methods and techniques of study such as leaf physiognomy, coexistence approach, dendroclimatology and climate analysis of endemic species, research precision has improved for qualitative analysis and quantitative reconstruction.In the present thesis, the Eocene palynoflora from Changchang Basin, Hainan Island has been studied, and the data used for the coexistence approach established by Mosbrugger & Utescher (1997) to reconstruct the climate and vegetation in this basin during Eocene time.Palynoflora recovered from Changchang Basin, Hainan Island is characterized by the dominance of angiosperm pollen, accounting for 94.5% of the total pollen and spores. Fagaceae pollen is overwhelmingly predominant among the angiosperm pollen, constituting 88.9% of the total...
