准噶尔盆地中央坳陷早侏罗世孢粉组合与古气候
The Early Jurassic sporo-pollen assemblages and paleoclimate of the central depression in the Junggar Basin
摘要
Abstract
According to palynological assemblages from the analysis of sporo-pollen sample collected in drilling hole, sporo-pollen assemblages of the Zheng 1 well in the central depression in the Junggar Basin were recognized by observing and identifying under microscope. The Lower Jurassic in the Zhengshacun of Juggar Basin can be divided into two sporo-pollen assemblages: the Cyathidites-Cycadopites assemblage from the Badaowan Formation and Cyathidites-Classopollis assemblage from Sangonghe Formation. By researching the kinship between the sporo-pollen assemblages and vegetation types, it is concluded that the Early Jurassic consists mainly of herbaceous Filicinae and arbor, Coniferales and ginkgo belonged to bush and cycad,and indicates that the paleoclimate belongs to subtropical climate.关键词
