///The study area, i. e. the southern margin region of the Wutai Mountain, is a conjoining region between the Jin-Yu-Shan in the southern part and the Yanliao Rift Troughs in the northern part of the Mesoproterozoic in the North-China Craton. A set of clastic rocks of the tidal-flat deposition system makes up the Changzhougou Formation, and a set of tidal-flat carbonate rocks does the Gaoyuzhuang Formation, both of which constitute the Mesoproterozoic of the study area. Its bottom boundary is an angular unconformity covering the Paleoproterozoic Hutuo Group, and top boundary is a leurodiscontinuity with a stratigraphic hiatus more than 1 000 Ma underlying the Cambrian system. Further, the research and introduction on sequence-sequence features that are marked by depositional successions for the Mesoproterozoic at the Chenjiazhuang section in Wutai County of Shanxi Province will provide a useful clue for further study on the Precambrian sequence stratigraphy in the North-China Craton.
