| 摘 要： | 修水地区志留系殿背组和坟头组腕足类化石自下而上分为：Ｍｅｒｃｉｅｌａ Ｚｙｇｏｓｐｉｒａｅｌａ组合；Ｎａｌｉｖｋｉｎａ Ｓｔｒｉｓｐｉｒｉｆｅｒ组合；Ｘｉｎａｎｏｓｐｉｒｉｇｅｒ Ｖａｌｄａｒｉａ组合，与川鄂等地志留纪腕足类生物地层带能很好地对比。通过对腕足类生态分异、共生分子及沉积相的研究，识别出４种腕足类生态类型，确认两组为一套中陆架—内陆架沉积。

| Abstract: | Brachiopods in the Silurian Dianbei Formation and Fentou Formation of the Xiushui area may be divided in ascending order into the Merciella Zygospiraella assemblage, Nalivkina Striispirifer assemblage and Xinanospirifer Valdaria assemblage, which can be correlated very well with the brachiopod zones in Sichuan and Guizhou. On the basis of the brachiopod ecological differentiation, coexisting elements and sedimentary facies, 4 brachiopod ecological types are recognized, and the two formations are ascertained as middle and inner shelf deposits. |

| Keywords: | Xiushui area Silurian brachiopods biostratigraphic sequence |
