| 摘 要： | 六盘山盆地海原凹陷肖家湾构造的海参1井钻遇中生代地层。其中安定组见孢粉化石Pinuspollenites-Ali-sporites-Araucariacites组合,时代定为晚侏罗世。和尚铺组含介形类和孢粉化石Cypridea(Cypridea)unicosta-ta-Cypridea(Ulwellia)koskulensis组合、Pinuspollenites-Classopollis-Schizaeoisporites组合和大量Peckisphaera paragranulifera,李洼峡组含轮藻和孢粉化石Aclistochara huihuibaoensis-Mesochara cf. voluta-Sphaerochara组合、Classopollis-Cicatricosisporites-Granudiscus组合和介形类Damonella cf. mediocris,Cypridea(Yumenia) sp.等,和尚铺组和李洼峡组的时代可归于早白垩世早中期(Hauterivian—Barremian)。乃家河组产轮藻化石Raskyae-chara sp.,Obtusochara cf. subcylindrica等,时代可能是晚白垩世。

| Abstract: | Well Haican-1 is located in the Xiaojiawan tectonic belt,Haiyuan Depression,Liupanshan Basin,Ningxia,and contains several Mesozoic units recognized from drilling cores. A sporopollen assemblage consisting of Pinuspollenites-Alisporites-Araucariacites indicates that the Anding Formation belongs to the Late Jurassic. An ostracode assemblage of Cypridea (Cypridea) unicostata-Cypridea (Ulwellia) koskulensis,a sporopollen assemblage of Pinuspollenites-Classopollis-Schizaeoisporites and numerous charophyte fossil... |
