| 摘 要： | 寒山金矿位于甘肃北祁连造山带西段、阿尔金大断裂带南侧.矿床受控于由阿尔金大断裂派生的北西向韧脆性剪切带中.文章从成矿地质条件、矿床地质特征等入手,分析了矿床的控矿因素,认为该矿床受含矿地层、韧脆性剪切带构造、岩浆岩等因素的制约.提出了新的找矿方向,认为韧脆性剪切带中的次级断层和矿体深部勘探,是该矿床今后找矿的重要方向.

| Abstract: | Hanshan gold deposit is located in the west part of north Qilian orogenic zone of Gansu, and south side of the Altyn fault belt. The deposit is controlled in NW - trending shear zone derived by Altyn fault. Based on ore - forming condition and ore geology, ore - controlling factors are analyzed. It is suggested that the deposit is controlled by ore - hosting strata, ductile - brittle shear zone and magmatism. New prospecting direction is proposed. Secondary fault in the ductile - brittle shear zone and deep part of ore body are the important direction for the next prospecting. |
