摘要: 塘上铅锌多金属矿床位于浙江省西南部的龙泉市宝溪乡,在详细地野外地质调查和 综合分析前人资料的基础上,对该矿床的成矿地质条件、找矿标志以及矿体特征进行了分析,探讨 了该矿床的成因。取得以下认识:①塘上铅锌矿床的矿石类型可分为石英脉型铅锌矿石和蚀变岩 型铅锌矿石;②塘上铅锌矿床热液蚀变主要有绿帘石化、绿泥石化、碳酸盐化、钾化、矽卡岩化、赤 铁矿化以及萤石化,铅锌矿化的强度与钾化、绿帘石和绿泥石化的强度为正相关关系;③塘上铅锌 矿床为热液型铅锌矿床。

Abstract: The Tangshang lead-zinc polymetallic deposit is located in Baoxi Township,Longquan City,southwestern Zhejiang Province. Based on detailed field geological survey and comprehensive analy⁃ sis of previous data,the metallogenic geological conditions,prospecting criteria and ore body characteris⁃ tics of the deposit are analyzed. The following understandings are obtained : ①The ore types of Tangshang lead-zinc deposit can be divided into quartz vein type lead-zinc ore and altered rock type lead-zinc ore. ② The hydrothermal alteration of Tangshang lead-zinc deposit mainly includes epidotization,chloritization, carbonation,potassiation,skarnization,hematite mineralization and fluoritization. The intensity of leadzinc mineralization is positively correlated with the intensity of potassiation,epidotization and chloritiza⁃ tion. ③Tangshang lead-zinc deposit is a hydrothermal lead-zinc deposit.
