| 摘 要： | 广西“南丹型”泥盆系以黑色泥岩为主,富含浮游生物竹节石等,是一套受基底构造控制的并受其两侧碳酸盐台地影响的台间海槽沉积。沉积相类型主要为深水含竹节石泥岩相,泥灰岩相及硅质岩相。台间海槽从益兰期开始出现,其形成和发展在塘丁—纳标—榴江期,封闭可能在早石炭世之后。

| Abstract: | The Devonian deposits of the Nandan type in northern Guangxi are composed mainly of dark mudstones, marls, which are typically of planktonic and nektonic facies. It is a deep water trough deposit that is controlled by the structure of basement, and affected by carbonate platform which is located in both sides of the trough, which expands from Yilan to Liujiang in ages. |
