| 摘 要： | 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，金矿定位于断裂带的扩容空间中，会林参数普遍表现为拉伸型，体积应变为增中型，金矿体就位于强应变与相对弱应变的转换部位，构造央垢有限应变椭球体拉伸轴主要中于ＮＥ－ＳＷ向，含矿热液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。

| Abstract: | Jiaojia fault is a very important gold mineralization zone in Eastern Shandong. Deformedquartz is widely developed in Jiaojia gold deposit. Three-dimension strain analysis of the quartzgrains indicates that gold deposit is located in dilation space of the fault zone, Flinn parametersare usually extension style, volume strains are raised. Gold ore is located in transfer sites betweenstrong and weak strain. The extensional axises of strain ellipsoid are mainly NE-SW direction.The ore fluid immigrates along Jiaojia fault zone. The ore-forming system is open and lots of materials are immigrated into the system during the mineralization. |
