| 摘 要： | 华北地台南缘,主要出露青白口纪—早古生代地层,属被动大陆稳定克拉通盆地发育过程,以台地碳酸盐沉积为主。通过对十余条实测剖面及主干、辅助路线的观察研究,青白口纪—早古生代奥陶纪早期,测区可区分出二个巨层序、十二个三级层序。本文通过三级层序的划分,建立了华北地台南缘青白口纪—早古生代奥陶纪早期层序地层格架、探讨了各岩石地层单位的变化规律。

| Abstract: | At the southern fringe of North China Platform are substantially outcrops of the Qingbaikou period-early Paleozoic strata,developed in passive continental craton basin and dominated by platform carbonate deposit.Based on more than 10 measured profiles as well as major and auxiliary routes of observation,the Qingbaikou period-early Paleozoic early Ordovician strata can be divided into 2 huge sequences and 12 three-class sequences in the surveyed area,on such basis,the sequence stratigraphy framework was set ... |
