摘要
芦子园铅锌多金属矿床位于"三江成矿带"南段保山—镇康地块,矿体赋存于上寒武统沙河厂组第二、三段(∈3s2、∈3s3)中的一套碳酸盐岩系中,矿体呈似层状、透镜状、脉状,严格受构造控制,矿体及其周围发育大量的矽卡岩矿物。通过各类岩(矿)石主量元素特征分析,并结合矿床地质特征,认为该矿床为赋存于碳酸盐岩地层中明显受构造控制的热液充填交代矽卡岩型铅锌矿床。
Luziyuan Pb-Zn polymetallic deposit is located at Zhenkang-Baoshan block which is in southern sec-tion of Sanjiang metallogenic belt.Ore-bodies occur in a set of carbonate rock series of ∈3s2 and∈3s3 of Sha-hechang Formation of Upper Cambrian System and they are in stratoid,lenticular and veined structures. Strictly controlled by tectonics,a large amount of skarn mineral occurs in and on the peripheral area of ore-bodies.After analyzing characteristics of major elements of various rocks （ores）and on consideration of geo-logical characteristics of the deposit,it is believed that the deposit occurs in hydrothermal packing and meta-somatic Skarn Pb-Zn deposit which is in carbonate formation and is obviously controlled by tectonics.
