| 摘 要： | 江西修水地区下志留统新开岭组中上部笔石化石自下而上可分为３个带：①Ｐｒｉｓｔｉｏｇｒａｐｔｕｓ ｃｙｐｈｕｓ－－Ｍｏｎｏｃｌｉｍａｃｉｓ带；②Ｐｒｉｓｔｉｏｇｒａｐｔｕｓ ｇｒｅｇａｒｉｏｕｓ带；③Ｍｏｎｏｇｒａｐｔｕｓ带。通过与其它地区同期笔石带对比，发现本区笔石动物群属扬子区和江南区的过渡类型，并且早志留世早期可能存在一定规模的间断。

| Abstract: | Graptolites in the middle-upper part of the Lower Silurian Xinkailing Formation in Xiushui area of Jiangxi can be divided in ascending order into the following three zones:1) Pristiograptus cyphus-Monoclimacis zone; 2)Pristiograptus gregarious zone; and 3)Monograptus zone. Correlation with other areas has revealed that the graptolite fauna in this area belongs in a transitional type between the Yangzi area and the Jiangnan area, and that a break of a certain magnitude may have existed in early Early Silurian times. |
