| 摘 要： | 在野外和室内工作的基础上,结合前人研究成果,对四川龙门山区北川县下泥盆统永利村谢家湾剖面进行了岩石地层、生物地层、层序地层及年代地层的多重地层划分,认为:1)研究剖面定为甘溪组谢家湾段较为合理;2)根据化石特征自下而上建立了Euryspirifer延限带和Otospirifer富集带;3)研究剖面属于典型的Ⅱ型沉积层序,由陆架边缘体系域、海侵体系域和早期、晚期高位体系域组成;4)研究剖面应属埃姆斯阶下部的中上部分,并可与广西、贵州相当地层进行对比。

| Abstract: | Base on the field work and previous achievements,identification and analysis of the sheet rock in the Lower Devonian section in Xiejiawan,Yongli village,Beichuan country,the Xiejiawan section,as a type section,was restudied in detail in Lithostratigraphic subdivision,Biostratigraphic subdivision,sequence stratigraphy subdivision and Chronostratigraphic subdivision.It is suggested that: 1) it is more reasonable that the Xiejiawan section belongs to the Xiejiawan subdivision,Ganxi Formation.2) Through the stu... |
