摘　　要：本文结合承德县西南沟银铅多金属矿地质背景,分析其各比例尺化探异常特征和矿化蚀变特征,初步明确了矿床成因。经土壤扫面测量及后期槽探查证,银铅锌矿化与区内分布的燕山期花岗斑岩体时空关系密切。银铅多金属矿化体受近东西向断裂控制,同时花岗岩为成矿提供了热源和物源,这为研究区后期找矿提供了借鉴。This article combines the geological background of the Southwest Gou silver lead polymetallic deposit in Chengde County,analyzes its various scale geochemical anomaly characteristics and mineralization alteration characteristics,and preliminarily clarifies the genesis of the deposit.Through soil scanning measurement and later trenching verification,it has been found that the silver lead zinc mineralization is closely related in time and space to the Yanshanian granite porphyry bodies distributed in the area.The silver lead polymetallic mineralization is controlled by nearly east-west faults,while granite provides heat and material sources for mineralization,which provides a reference for later exploration in the study area.
