| 摘 要： | 四川东北寨金矿床严格受岷江南北向构造带的垮石岩断裂带的控制。该断裂可分为8个构造岩带,各带在成矿过程中具不同的控矿作用。构造动力作用于岩体使之产生形变破碎、驱动含矿流体运移、加热、元素活化迁移及组分分异等。断面形态的空间变化既控制矿体的赋存部位,又是构造岩带差应力和最小主应力的突变界面,其变化显著部位是成矿的有利地段。

| Abstract: | The Dongbeizhai gold deposit is strictly controlled by Kuashiyan fault zone which is a partof north-south tectonic zone of Mingjiang. The fault zone can be divided into eight tectonic subzones.Each of them has it's own controlling mineralization in the minerogenetic process. As the kinetic tec-tonism acted on the rock body, and made it to be deformed. Meanwhile the ore solution was to be heat-ed and driven. The elements were to be activated, and the composition was to be segregated. The spatialchange of the fault shape not only controlled the position of orebody but also was a abrupt interface ofstress difference, and also of minimum principal stress. The significantly deformed position of fault sur-face is advantageous for mineralization. |
