| 摘 要： | 辽宁义县金家沟义县组砖城子层的孢粉组合是以无肋双囊类花粉为主(占组合的70%左右),伴以少量Cicatricosisporites,Jugella,Ephedripites,Jiaohepollis等为特征,其基本面貌与北票黄半吉沟义县组尖山沟层的孢粉组合类似,时代同属早白垩世贝利亚斯期,反映温暖湿润的气候环境。

| Abstract: | The Zhuanchengzi Beds are the basal sedimentary interbeds in the Yixian Formation,a volcanic-sedimentary rock sequence distributed in Yixian area (Wang et al.,2003).The palynological assemblage from the Beds is dominated by non-striate bisaccate pollen (about 70% in content),associated with a few pollen and spores of Cicatricosisporites,Jugella,Ephedripites,Jiaohepollis,Classopollis etc.,but lacks any angiospermous pollen.This assemblage is very close to that from the Jianshangou Beds,the basal beds of the ... |
