Abstract
Three exposures of the Upper Ordovician Xiazhen Formation at Zhuzhai, Yushan, Jiangxi Province, China are re-measured and described in detail. Comparison of palaeontological and lithological data from the exposures (designated sub-sections ZU1, ZU2 and ZU3) reveals that the sub-sections overlap stratigraphically. Nearly identical assemblages of trilobites and brachiopods occur in mudstones of ZU1 and ZU3, whereas a different assemblage occurs in those of ZU2. Identical coral species occur in the overlapped intervals of ZU1 and ZU2, and ZU1 and ZU3, respectively. In addition, a distinctive identical lithological succession consisting of brachiopod-bearing nodular limestone at the base to coral floatstone at the top is evident in the overlapped interval of ZU1 and ZU2; prism-cracked algal laminites are found in the same interval; and bioclastic limestone beds, which represent bioherms consisting mainly of corals and stromatoporoids, occur in both ZU1 and ZU3. A thrust fault system appears to be responsible for the repetition in the subsections, and the faulting was probably due to the major post-Ordovician structural movements exerted on the Zhe-Gan Platform of the Jiangnan Region of the South China Block.
