| 摘 要： | 在区域性盆地研究的基础上,通过对沙拉岗锑 (金 )矿区沉积相与层序地层分析,初步识别出Ⅰ类和Ⅱ类不同性质的层序界面,划分出 8个三级层序,包括 2个Ⅰ类层序和 6个Ⅱ类层序,所有层序均具有清晰的三分结构。将江孜盆地斜坡背景的沉积充填演化划分为四个阶段:相对陡的陆源斜坡阶段、相对平缓的陆源斜坡阶段、硅质海底扇阶段、陆源海底扇阶段

| Abstract: | Based on the detailed regional geological setting analysis,this paper deals with the research of ore bearing basin,the depositional facies and sequence stratigraphic analysis have been done for the first time in Shalagang mining region.And all kinds of characteristic gravity flow sediments,for erample,slide,debris flow and turbidity deposits,are significantly documented. Siliceous submarine fans made up of different grain sizes and different types of siliceous rock are also discovered for the first time in Gyangze basin.The evolution stages of depositional filling with slope setting are divided in Gyangze basin |
