摘　　要：保山―镇康地块位于澜沧江断裂带和怒江断裂带之间,是重要的铜、铅、锌、铁、金、银等多金属成矿带,芦子园铅锌矿床是近年来经勘查发现的发育于此成矿带内的超大型铅-锌-铁-铜多金属矿床。目前对于芦子园铅锌矿床主要矽卡岩矿物类型的厘定以及矽卡岩矿物特征的研究环节较为薄弱。本文在详细的光、薄片鉴定分析的基础上,据矿床地质特征、矿物共生组合及相互穿插关系,表明该矿床的形成具有多期多阶段性,对矽卡岩矿物进行系统研究,详细把握该矿床主要矽卡岩矿物类型和矽卡岩矿物特征及矿化期次,对完善矿床成因及指导矿石选冶都有十分重要的意义。Located between Lancang River fault zone and Nujiang River fault zone,the Baoshan-Zhenkang land block is an important polymetallic metallogenic belt of Cu,Pb,Zn,Fe,Au,Ag,etc.Luziyuan Pb-Zn deposit is an ultra-large scale Pb-Zn-Fe-Cu polymetallic deposit which was developed in this metallogenic belt and was found in recent years.At present,the research on main types of Skarn minerals in Luziyuan Pb-Zn deposit and the characteristics of Skarn minerals is inadequate.Based on the detailed optic and thin section authentication,and according to the geological characteristics of deposits,paragenetic association of minerals and its interrelationship,this paper shows that the development of this deposit consists of multiple phases, and it performs systematic research on the Skarn minerals,and determines the main types of Skarn minerals in the deposit and the characteristics and mineralization epochs of Skarn minerals.This article completes the research on genesis of the deposit and can be used as guidance in dressing and processing of ores.
