滇西云龙锡矿床处于马来西亚锡矿带北延段,澜沧江、怒江与温泉断裂夹持的三角地带。含锡地层主要为下古生界崇出群(Pzch)的一套混合岩化岩石。主要锡矿体均赋存于断裂发育、层间滑动带及硅化、电气石化强烈的碎裂混合花岗岩内,呈脉状、似层状“盲矿“隐伏于地表之下20—150米深处。常见共生金属矿物有黄铁矿、磁黄铁矿、毒砂、锡石等硫化矿物,很多地质学者认为该矿床属高温热液矿床。
The Yunlong-tin deposit in western Yunnan is located in the delta zone of the northern extension of the tin belt in Malaysia, the Lancang River and the Nu River and the hot spring fracture. The tin-bearing strata are mainly a set of mixed petrified rocks of the Lower Paleozoic Pzch. The main tin deposits are hosted in the development of faults, interlayer sliding zone and silicification, electrocracking strong fission mixed granite, was veins, like stratiform “blind mine” hidden in the depths of 20-150 meters below the surface . Common symbiotic metal minerals are pyrite, pyrrhotite, arsenopyrite, cassiterite and other sulfide minerals, many geologists believe that the deposit is a high-temperature hydrothermal mineral deposits.
