%X Some of our views on the correlation of graptolite and some shelly fossil sequence from the latest Ordovician to earliest Si'urian and on the division of the Ordovician-Silurian boundary have been presented in the past papers (Wang et al., 1980, 1983a, b; Lai et al., 1982; Xu et al., 1983). The present paper will further inquire into these problems in the light of biostratigraphy, isotope age dating sedimenatry facies and priliminary paleomagnetic research from the Ordovician-Silurian boundary sections of the eastern Yangzi (Yangtze) Gorges (pl. 1-2).
