摘要
岩峰锡矿矿体呈脉状,赋存于北西向断层构造破碎带中,矿体围岩为三叠系上统湾甸坝组上段(T_3wn^2)之灰色岩屑长石石英杂砂岩;与锡矿有关的矿化主要有硅化、电气石化;属高-中温热液交代充填锡石—石英电气石型锡矿床。
The ore body of Yanfeng Sn dep [osit is veined in NW fault fracture zone. The wall rock Upper Triassic Wandianba Formation Upper Member（ T3wn2） gray debris feldspar quartz greywacke. The alteration in relation to the Sn deposit is silicification,tourmalinization,belonging to the high-middle T hydrothermal metasomatic filling cassiterite-quartz tourmaline type Sn deposit.
