白牛厂矿区发育在多旋回演化的裂谷盆地之中 ,超大型银多金属矿床由中寒武世海底喷溢沉积作用形成。海底热液来源于裂谷盆地沉积物中超高压流体 ,热液属于富含 K+、SO2 -4的卤水 ,w ( Zn) /w ( Zn+Pb) <0 .7,与世界超大型 SEDEX矿床特征相似。滇东南下寒武统可能为重要的矿源层 ,该区具有良好的找矿前景
The White Cattle mining area is developed in a multi-cycle evolution rift basin, and the superlarge silver-polymetallic deposit is formed by the mid-Cambrian seabed overflowing and sedimentation. The seabed hydrothermal fluids originate from the ultrahigh-pressure fluid in the sediments of the rift basins. The hydrothermal fluids belong to brine rich in K +, SO2-4, w (Zn) / w (Zn + Pb) <0.7, similar. The Lower Cambrian in southeastern Yunnan may be an important source rock, which has a good prospects for prospecting
