我国部分地区E1^3—E2^1孢粉属种演变的古气候意义

PALAEOCLIMATIC IMPLICATION OF THE DEVELOPMENT OF PALYNOLOGICAL SPECIES AND GENERA FROM THE LATE PALEOCENE TO THE EARLY EOCENE IN SOME AREAS, CHINA

通过对我国部分地区古新世晚期 -始新世早期孢粉植物群演化发展规律的分析研究 ,结合国内外地层学研究的新进展 ,提出我国古新世晚期气候以暖湿为特征 ,且暖期的结束与始新世 /古新世界限相吻合或接近 。

Based on the study of development of palynological flora from the Late Paleocene to the Early Eocene in some areas, China, it is suggested that the paleoclimate condition in Late Paleocene in China was warm and wet. The end of warm and wet climate was coincident with (or near at least) the boundary between the Paleocene and the Eocene, which can be regarded as the top of Paleo- cene.
