青海省金矿资源比较丰富,原生金矿,砂金矿以及伴生金矿均有。其中松树南沟金矿物化探方法找矿效果较好,特别是磁法和次生晕方法很有效,起到了间接和直接的找矿效果。 一、矿区地质概况 松树南沟金矿位于红沟矿带的中部,属北祁连加里东褶皱带。矿区构造简单,为一走向北西西,倾向南西的单斜构造。地层为上奥陶统下火山岩组,以细碧玢岩为主,其
Qinghai Province, rich in gold resources, primary gold, gold sand and gold associated with both. Among them, the method of gold and geophysical and geochemical exploration of the Nanchong gold deposit in the Songqin River is better, especially the magnetic and secondary halo methods are very effective and play an indirect and direct ore prospecting effect. I. Geology of Mining Area The Songqin Nanogou gold deposit is located in the middle part of Honggou ore belt and belongs to the North Qilian Caledonian Fold Belt. The mining area has a simple structure and is a monoclinic structure that goes northwest and west and tends to the southwest. The strata are Upper Ordovician volcanic formations, dominated by fine bi-rock
