摘　　要：生物地层学是地层学中最基本的也是应用最广泛的一个分支学科。通过多年来对华南扬子区、江南过渡带到珠江区奥陶纪和志留纪生物地层学的研究 ,不但完善了地层的精确对比 ,而且结合岩相、生物相的研究 ,还对广西运动的始末提供了准确的时限 ,从而延伸到大地构造学的研究领域中 。Biostratigraphy is one of the basic and widely applied branches in stratigraphy. The studies of the Ordovician and Silurian biostratigraphy from the Yangtze region through Jiangnan transitional belt to the Zhujiang region provide a precise correlation of this interval. Combining with the study of lithofacies and biofacies,it dates the begining and closing of the Kuangsi orogeny. Thus,a biostratigraphic study extends into the field of tectonics.Italso makes a connection between regional and global tectonic events.
