The researching region is located in the north eastern part of North 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, middle to large solid coral and massive coral has all been found. The diversification of the coral genera and species and the proportion of the 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 tropical-subtropical zone (near equator) in the Late Carboniferous.
