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。
The Middle Proterozoic Shuangqiaoshan Group in Northern Jiangxi Province is a complete turbidite fan body. Among them, the Cilin Group has turbidites sequence with far-end source and lack of bottom, the structure of underwater flow is very developed, the ancient flow is single, the interaction between purple and gray-green is the characteristic sign of the external fan. Strengthening the study on fan deposition in the Cering Forest Group can greatly deepen the study on the basic geology of the former Sinian in the north Jiangxi Province.
