Abstract

This paper analyzes both from the ecozone divisions of shell fauna including Kinnella-Plectothyrella zone (< BA3), Draborthis-Toxorthis zone (BA3-4) and Paromalomena-Aegiromena zone (BA4-5) or some other elements (indicating ecospheres of < BA3 or > BA4-5), and from the combination of the lithology of rock containing these shell faunas, sedimentary, the differentiation features inside the Yangtze ocean basin that could be divided into central deep-water basin with black siliceous shale (> BA4-5), eastern neritic clastic basin (mainly in BA4-5) and western neritic carbonate rock-clastic rock (mainly in < BA3) parts. This paper also probes the changes of water-depth from south to north in the above-mentioned parts of the Yangtze basin. In the central basin, from south to north, the Yangtze basin became deeper and deeper, indicating that, in the south it is deeper from BA4-5 and in the north, much deeper from BA4-5, with the depositional center located in Hubei and the middle of Hunan. In the western basin, from south to north, the Yangtze basin became deeper, that is, in the northern Guizhou and eastern Sichuan, the corresponding ecozone was located in < BA3, and in the northern Sichuan and southern part of Shaanxi, the ecozone is located in BA4. In the eastern basin, from south to north, the Yangtze basin also became deeper and deeper, for example, in Tonglu and Changshan, the corresponding ecozone is located in < BA3, while in Jingxian and Nanjing, it is located in ≥BA4-5.
