Pollen-Based Reconstructions of the Ek1 and the Lower Part of Es4 of the Paleogene Vegetation and Climatic Characteristics in Dongying Depression
Abstract:
Based on the analyses of pollen samples from Well Haoke-1, this paper studies the Paleogene pollen sub-assemblage sequences of the Ek1 and the lower part of Es4 in Dongying Depression. Four sub-assemblages are distinguished, and then four phases are recognized. Through the study, it is found that the Ek1 and the lower part of Es4 in Dongying Depression belonged to the climate of subtropical semi-arid zone and the seasonal differences of climate became increasingly great with the evolution of the earth.
