| 中文摘要: |
| 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。 |
| 英文摘要: |
| Jiaojia fault is a very important gold mineralization zone in Eastern Shandong. Deforme dquartz is widely developed in Jiaojia gold deposit. Three-dimension strain analysis of the quartz grains indicates that gold deposit is located in dilation space of the fault zone, Flinn parameters are usually extension style, volume strains are raised. Gold ore is located in transfer sites between strong 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. |
