| 摘 要： | 弥沙河断裂带为金沙江断裂带的南段，其构造变形复杂。该断裂带由构造混杂带和推覆构造带两个构造单元组成。构造混杂带宽约２ｋｍ，由劈理化基质和构造岩片组成。推覆构造带由五套推覆体构成。这些推覆体在空间上层层叠置，并形成构造倒序结构。弥沙河断裂带的早期活动是在晚海西期，大规模的逆冲－推覆作用是在喜马拉雅期。

| Abstract: | The Mishahe fracture complicated in the structural deformation , is the southern section of the Jinshajiang fracture. The fracture is composed of the tectonic melange zone and the nappe structure zone.The former 2 km wide,is made up of the cleavaged base and the tectonic slice, the latter is composed of five nappes.These nappes are overlapped one after another in space and form the construction of structural reversed order.The early active period of the Mishahe fracture is in the late Hercynian stage, while the large scaled thrust nappe is during Himalayan stage. |
