摘要
云南澜沧老厂银铜铅锌矿床为我国西南三江地区重要的多金属矿床.文中综合分析了该矿床的地质特征,认为其成因与火山喷流沉积作用、火山期后热液改造作用密切相关,成矿流体为岩浆水和大气降水或海水的混合水,成矿物质主要为幔壳混合来源.
The Laochang Pb＋Zn deposit in Lancang, Yunnan Province is an important polymetallic ore deposit in the Sanjiang area in Southwest China. Based on a comprehensive analysis on the geological characteristics of the deposit, its origin is considered to be closely related with volcano-eruption sedimentation metallogenesis and post-volcanic exhalative hydrothermal reformation metallogenesis. The metallogenic fluid is the mixture of magmatic water and meteoric or sea water. The source of ore materials is crust-mantle mixture.
