摘　　要：夏家庄铁矿床是宁芜矿集区西南部雍镇矿田内的代表性铁矿床,但有关夏家庄矿床的成因研究目前还比较薄弱,阻碍了对雍镇矿田的认识。通过该区内区域地质特征、矿床地质特征及其他找矿信息的阐述,结合矿区地质工作成果,详细分析了成矿物质来源和成矿环境,总结了矿床成因。研究发现,岩浆岩与围岩接触带构造中的岩凹构造是本区主要的控矿构造;膏盐层为后期矿质沉淀提供有利空间,是研究区重要成矿特征;寻找下接触带磁铁矿体是本区下一步找矿方向之一。The Xiajiazhuang Iron Deposit is a representative iron deposit in the Yongzhen ore field in the southwest of the Ningwu Ore-concentrated Area.However,the research on the genesis of the Xiajiazhuang deposit is still relatively weak,which hinders the understanding of the Yongzhen ore field.Through the elaboration of regional geological characteristics,geological characteristics of deposits and other prospecting information in the area,combined with the results of geological work in the mining area,the source of metallogenic materials and metallogenic environment are analyzed in detail,and the genesis of deposits is summarized.It is found that the rock concave structure in the contact zone between magmatic rock and surrounding rock is the main ore-controlling structure in this area.Gypsum salt layer provides favorable space for later mineral precipitation,which is an important metallogenic feature in the study area.Finding the lower contact zone magnetite ore body is one of the next prospecting directions in this area.
