阳山金矿自1997年发现以来，进行了不间断的勘查和科研工作，矿床规模不断扩大。其中阳山矿段发现23条金矿脉，以2号脉和13号脉为主，估算金资源量12957kg。前期激电中梯度测量高极化率异常显示较强，说明阳山矿段矿脉群还有继续研究的潜力。本文将衍生指数法应用于激电测深工作中，对13号脉群西延段进行研究，掌握了其空间分布规律，经钻孔验证，取得了很好的效果，对本区浅部矿产勘查具有指导意义。

With continuous exploration and scientific research work,the deposit scale expands unceasingly in Yangshan since gold deposits were found in 1 997.23 gold veins were discovered in Yangshan ore block,and No.2 and No.13 veins are primary ones in amount with the estimated gold resource amount of 12957kg.In the earlier stage,the IP gradient method shows anomalies of high polarizability,which indicates that vein groups in Yangshan ore block have prospecting potential.In this paper,derivative index method was applied in the research on west extension section of No.13 vein by the IP sounding method,and its spatial distribu-tion was determined.It has been verified by drilling and ideal results also have been achieved which has guid-ing significance in shallow mineral exploration of this area.
