| 摘 要： | 秦岭－大别山是分隔中国南北大陆的重要造山带，对于中国大陆构造的形成与演化起着重要的控制作用。但由于南襄盆地的阻隔，人们对分处盆地东西两侧的东秦岭与桐柏－大别山是何关系？长期以来众说纷纭，莫衷一是。本文利用南襄盆地石油勘探开发进程中的钻井、物探资料，结合盆地周缘地层的岩性、岩相、构造相、古生物、同位素年龄测定、构造关系等资料，分析了前中生界展布规律，研究结果认为桐柏－大别山实即东秦岭的自然延伸部份。

| Abstract: | Qinling-Dabie Mountain, which is the main orogenic belt dividing the south and north continents of China, controlled the formation and evolution of tectonic structure of China. For a long time, there are different opinions about the relation between East Qinling and Tongbai-Dabie Mountain,located in the western and eastern parts of Nanxiang Basin respectively, and it is unable to decide which opini0n is right. The distribution of Pre- Mesozoic is analyzed in this paper using drilling and geophysical data co1lected during petroleum exploration and development in Nanxiang Basin and combining the lithology, lithicfacies, palaeobiology,isotopic age and structural relation, and it is concluded that Tongbai-Dabie Mountain is actually the natural extention of East Qin1ing. |
