江西省上高县七宝山铅锌铁钴矿床为一个半隐伏矿床,矿体均产于高岽山背斜的北西翼F1逆掩断层的下盘.面积为0.33 km2.矿化具一定分带性,矿体严格受地层层位控制,分别赋存于棋子桥—余田桥组、锡矿山组及黄龙组中.岩层和构造是该矿区金属工业矿床形成的主要因素,但本矿区的热液作用,也是主要条件.矿床形成作用分为两个阶段:在沉积成岩阶段中,成矿物质初始富集,局部矿体已成雏形.在后期改造阶段中,伴随印支、燕山运动,地温增高,地下热水循环作用加强,成矿元素经迁移,沿断层上侵,在有利空间,叠加富集、改造同生层状矿体或贫矿层.%The Qibaoshan lead and zinc iron cobalt deposit in Shanggao county Jiangxi province is a subconcealed deposit, ore bodies is produced in the footwall of F, overthrust fault to the north of the west wing Gaoong shan anticline. Area is 0. 33 square kilometers. Mineralization with a certain zoning, ore strictly controlled by the strati-graphic position, respectively, occur in the group Qizi qiao- Shetian, Xishangroup and Huanglong group. Rock stratum and construction are the main factor which the metal industry deposit forms, but the mining of hydrother-mal, it is also the main conditions. The role of deposit formed in two stages: in the diagenesis stage, as the initial concentration of minerals, has become the prototype of the local ore. In the later stages of transformation, with the Indosinian movement, Yanshan movement, soil temperature increased, strengthening the role of geothermal water circulation, forming elements by the migration of the intrusion along the fault, look for favorable space transformation , superposition of syngenetic stratiform ore bodies enriched or depleted seam.
