研究区位于华北板块的东北部，晚石炭世为海陆交互相沉积。海相灰岩层中产有大量珊瑚、(竹蜓)、腕足类及双壳类化石。共描述皱纹珊瑚7属15种，其中新种11个，1个未定种。珊瑚化石组合中，小型单体珊瑚、中大型单体珊瑚和群体珊瑚共同繁育，种属分异度高，且地方性种数量大，表现为热带-亚热带生物区系的特点，说明华北板块晚石炭世古地理位置应位于古赤道附近的热带-亚热带，为古特提斯洋中的古板块之一。

The researching region is located in the north ea stern part ofNorth China Plate. The Late Carboniferous depositional environment of this region was alternate phase of marine and continent. There are a lot of Coral, Fusulinacea, Brachopoda and Bivalvia fossils in the marine strata. 7 genera and 15 species including 11 new species and 1 undefined species have been described in this paper. Among the coral assemblage, the minor solid coral, mid dle to large solid coral and massive coral has all been fou nd. The diversification of the coral genera and species and the proportion of th e endemic species are high, which may hint that the coral assemblage belongs to tropical and subtropical provincialism. We may also conclude that the North China Plate, as one of the paleo-plates in Tethys, was located in tropi cal-subtropical zone (near equator) in the Late Carboniferous.
