摘要
本文阐述了研究区地质特征及成矿地质条件,对控矿因素进行分析和探讨,总结成矿规律,为下一步找矿方向提出建议。安徽泾县芦椒山铅锌多金属矿矿床类型为中低温热液型矿床,矿体受控于北东向构造,具有钼—铜—铅锌分带特征、成矿温度自中高温到中低温转变的特点,含矿热液物质来源于燕山期上侵的岩浆,与燕山期茂林岩体及中酸性脉岩相关。
This paper describes the geological characteristics and metallogenic geological conditions of the study area,analyzes and discusses the ore-controlling factors,summarizes the metallogenic rules,and puts forward suggestions for the follow-up mineral exploration targeting.The Lujiaoshan Pb-Zn polymetallic deposit in Jingxian County,Anhui Province is a middle and low temperature hydrothermal deposit with ore body controlled by NE-trending structure.It exhibits Mo-Cu-Pb-Zn zonation,and mineralization of change from medium-high to medium-low temperature.The ore-bearing hydrothermal materials originate from the Yanshanian overthrusting magma,and are related to the Yanshanian Maolin rock mass and intermediate-acid dyke rocks.
