| 摘要: |
| 赣北中元古界双桥山群是一个完整的浊积扇体。其中计林组具有远源缺底的浊积序列、水下流动构造甚为发育、古流向单一、紫红色与灰绿色交互等特点,为外扇沉积标志。加强对计林组外扇沉积作用研究,可以大大深化赣北前震旦纪基础地质研究。 |

| Abstract: |
| The Mesoproterozoic Shuangqiaoshan Group in northern Jiangxi appears as a complete turbidite fan. The Jilin Formation of the Group as an outer fan is characterized by the distal turbidite fan sequences,well-developed submarine flow structures,simple palaeocurrents,and alternating purplish red and grayish green rock beds. The study of the outer-fan deposition may assist in the examination of the pre-Sinian geology in northern Jiangxi. |
