| 摘 要： | 本文对北部湾XI钻孔岩芯中各种沉积相中的重矿物组合分别作了研究,结果表明,在湖相沉积物中自生黄铁矿物含量高,滨海相沉积物中稳定矿物(钛铁矿、电气石、锆石)特别富集,浅海相沉积物中则出现大量的自生海绿石,由此说明,重矿物组合的研究对阐明沉积相是有其重要意义的。

| Abstract: | The heavy mineral assemblages of different sedimentary facies were studied in the XI Core sediment samples of Beibu Gulf . The study results show that the high content of authigenic pyrite is found in the lake facie sediments. The stable minerals (ilmenite, tourmaline, zircon) are concentrated in the littoral facie sediments. A lot of authigenic glauconite are widely distributed in the shallow sea facie sediments. According to above data, it may be concluded that the study of heavy mineral assemblages is important for understanding of the sedimentary facies. |
