江西赣中铁矿位于江西省新余市，属沉积变质型铁矿，围岩均不具有磁性，具备磁法勘探找矿的物性基础。赣中铁矿矿体具有薄且深的特点，以往对矿区磁法勘探的资料解释工作未取得较好效果，勘探工作多以地质勘查和钻探为主。在充分了解研究区工作现状的基础上，利用小波分析方法对杨家桥矿区磁异常进行了多尺度分解，提取了深部场并加以解释；将重磁异常边界识别技术应用到磁测资料的解释中，划分了深部找矿远景区；最后，应用井中三分量磁测资料解释技术对松山工区62勘探线进行了精细反演解释，提供了定量解释结果，指出井中三分量磁测是寻找深部矿的有效方法，为赣中铁矿深部及外围找矿提供了新的工作思路。

Located in Xinyu City, Jiangxi Province, the Ganzhong iron deposit is a sedimentary metamorphic iron deposit. As the coun?try rock in this area is non-magnetic, we have the base of physical properties to implement magnetic survey. The iron formation is thin and deep in this area. So far, the interpretation of the magnetic data has not achieved good results. The previous work was mainly fo?cused on the geological exploration and drilling. In this paper, the authors first studied the status of the geological work in the study are?a, and then used the wavelet multi-scale decomposition method to extract the deep field anomaly. The method of tilt-angle and the Theta Map was also employed to identify the boundary of the iron formation and, as a result, five prospecting areas were delineated which have good metallogenic potential. In addition, the authors applied meticulous inversion and interpretation along No. 62 exploration line of Songshan area based on the borehole data of ZK6209 and provided a quantitative interpretation result. It is pointed out that three-component borehole magnetic survey is an effective way to find the deep iron formation. This paper provides some new i?deas for the deep and peripheral prospecting in the Ganzhong iron deposit.
