| 摘 要： | 应用地质异常致矿、控矿理论和ＧＩＳ空间结构分析方法，探讨川西北地区金成矿的地质异常控制。研究结果表明，该区金矿的形成玑分布明显受控于各类致矿地质异常，并显示一定的内在成生联系和时空配置关系。其中大地构造格架、区域构造样式对本区金矿化的区域性展布及产状起主导控制作用；地层－岩相组合异常、岩浆活动及热源异常对金成矿的物质来源和热动力条件有密切关系和重要影响；而深部构造异常结构与金矿床（点）的产出与分布

| Abstract: | Geo anomly confrol of Au mineralization in northwest Sichuan province is discussed on basis of the theory of geoanomly leading to ore and control on ore and GIS analysis method. The results show that formation and distribution of Au ore in the area are clearly controled by various geo anomlies which always lead to ore and are in inherent genetic and spatial and temporal relation. Geotectonic frame and regional structure style dominate the regional distribution and occurrence of the mineralization. Strata rock facies association anomly, magmatism and heat source anomlies are closely related to ore forming material source and dynamic condition, pattern of the deep structures matchs directly to the occurrence and distribution of Au doeposits and targets. Then creteria for regional geo anomly prospect are pointed out. |
