枣庄地区寒武纪—早奥陶世处于被动大陆边缘陆棚环境 ,沉积序列受海平面的周期性变化所控制。由寒武系底部不整合面和怀远运动间断面所限定的地层组合 ,可划分为A ,B两个二级层序和 1 2个三级层序 ,其中张夏组底界面与二级层序底界面一致 ,为一个由陆源浑水沉积环境向碳酸盐清水沉积环境演化的转换面
The Cambrian-Zao’aozao area in Zaozhuang area is in the continental margin of the passive continental margin, and the sedimentary sequence is controlled by the periodic change of the sea level. The stratigraphic combination, defined by the unconformity at the bottom of the Cambrian and the inter-section of Huaiyuan Movement, can be divided into two second-level sequences A and B and 12 third-level sequences. The bottom boundary of Zhangxia Formation and the second-level The sequence bottom interface is the same as that of a transition surface from the terrigenous muddy water sedimentary environment to the carbonate clear water sedimentary environment.
