摘　　要：江西宝山矿床位于南岭东西复杂构造带东段,诸广山隆起带的铅厂断陷盆地,区域成矿条件优越。为解决宝山矿区的深部找矿问题,在总结矿床地质特征的基础上,通过控矿因素和探采资料分析,得出“岩性+花岗岩顶面凹槽”的控矿规律,且凹槽的形态、产状和大小,直接控制着矿体的形态、产状和规模。结合矿床成因的分析探讨,建立了成矿模式,预测在茅草沟区段深部-500~-800 m深处可能存在另一个大的凹槽构造,具有较好的找矿远景。The Baoshan deposit in Jiangxi Province is located in the eastern part of the Nanling EW complex structural belt,and in the Qianchang fault basin of Zhuguangshan uplift belt.The regional metallogenic condition is superior.In order to solve the problem of ore prospecting at the deep place in Baoshan mining area,on the basis of summary of the geological characteristics of the deposit,and the analysis of ore controlling factors and exploration and mining data,the ore controlling regularity of"lithology+granite top groove"is obtained,and the shape,occurrence and size of the groove structure directly control the shape,occurrence and scale of the ore body.Based on the analysis and discussion of the genesis of the deposit,the metallogenic model is established,and it is predicted that there might be another large groove structure at the depth of-500—-800 m in the Maocaogou section,which has a good prospecting prospect.
