| REDISCUSSION ON THE DIVISION AND CORRELATION OF THE ORDOVICIAN-SILURIAN BOUNDARY |
| Some of our views on the correlation of graptiolite and some shelly fossil sequence from the latest Ordovician to earlist Silurian 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). |
