焦家金矿床构造岩中广泛发育变形石英颗粒,这些变形石英颗粒的三维有限应变分析表明:金矿床定位于断裂带的扩容空间中,付林参数普遍表现为拉伸型.体积应变为增加型。金矿体就位于强应变与相对弱应变的转换部位。构造岩的有限应变输球体拉伸轴主要集中于NE一SW向,含矿热浪运移方向与焦家断裂带平行.成矿过程中体系是开放的,有大量体系外物质迁入。
The deformed quartz grains are extensively developed in the tectonic rocks of Jiaojia gold deposit. The three-dimensional finite strain analysis of the deformed quartz grains shows that the gold deposits are located in the expansion space of the fault zone, and the parameters of the forking are generally tensile. Volume strain to increase type. Gold ore body is located in the strong strain and relatively weak strain conversion site. Tensile axis of the finite strain lose body of tectonic rocks mainly concentrates in NE-SW direction, and the migration direction of the ore-bearing heat waves is parallel to the Jiaojia fault zone. In the process of mineralization, the system is open, and a large number of materials outside the system are moved in.
