Shoaling-upward succession of the Miaolingian Zhangxia Formation at the Anjiazhuang section (location is shown in Fig. 2). a The succession consists of a third-order sequence (equals to DS5 in Fig. 1) which is further subdivided into three subsequences (I to III, as seprated by dotted lines). The upper part of subsequence III comprises three parts, i.e., b, c, and e, upwards, representing three types of carbonate rocks as follows; b Oncolitic- and oolitic-grainstones; c, d Massive oolitic grainstones; e Massive limestones dominated by dendrolites with the intergrowth of leiolites, which is the key target of this study
