| 摘 要： | 苏浙皖交境地区沉积了一套岩性比较稳定的早石炭世地层——金陵组 ,保存于该套地层中的生物化石有腕足类和孢粉化石。孢粉组合中的主要分子 Densosporites、Cymbosporites、Dibolisporites、L ycospora通常分布在早石炭世 ,可与我国许多地区 (如新疆准噶尔盆地滴水泉组 )的孢粉组合对比 ,反映该区金陵组属早石炭世杜内期(Toum aisian)沉积物。综合生物化石和岩石学特征 (包括沉积构造、岩石组分等 )的研究 ,金陵组为海陆交互相沉积环境。

| Abstract: | Stable Early Carboniferous strata (Jinlin Fm.) were deposited at the border between Jiangsu,Zhejiang and Anhui, where fossil brachiopods, sporopollen are preserved. Sporopollens are dominated by Zonotriletes spores (Densoporites, Cymbosporites, Dibolisporites, Lycospora). These fossil spores usually occur in the Early Carboniferous. This sporopollen assemblage may be compared with that from the Dishuiquan Fm.of the Juggar Basin and shows an Early Carboniferous Tournaisian age. The synthetic study of fossils and lithological character (including sedimentary structures, lithological components, color etc.) indicate a marine-continental sedimentary environment for the Jinlin Formation. |
