| 摘 要： | 辽宁瓦房店金刚石矿田是我国重要的金伯利岩型金刚石矿集区.为了更好地发挥物探在该区寻找金刚石矿的作用，对以往物探工作程度、使用的方法、取得的成果进行了系统梳理.通过总结发现，地面磁测在圈定浅地表金伯利岩体中发挥了重要作用；在寻找深部隐伏金伯利岩体时，音频大地电磁测量、井中物探发挥了重要作用；在研究金刚石矿控矿因素等问题时，1∶5万区域重力测量、大地电磁剖面测量发挥了重要作用.总之，物探是瓦房店矿田金刚石矿勘查中的重要组成部分，合理的方法组合能够解决相应的地质问题.

| Abstract: | The diamond orefield in Wafangdian of Liaoning Province is an important kimberlite-type diamond concentration area in China. The work degree, methods and achievements of previous geophysical prospecting are systematically analyzed so as to better apply geophysical prospecting for diamond deposits in the area. It is concluded that ground magnetic survey plays an important role in delineating shallow-surface kimberlite rock mass; audio magnetotelluric (AMT) survey and borehole geophysical exploration in the search for deep concealed kimberlite rock mass; while the 1:50 000 regional gravity survey and magnetotelluric profile survey, in the study of ore-controlling factors of diamond deposits. To sum up, geophysical prospecting is an important part of diamond exploration in Wafangdian orefield and reasonable combination of methods can solve corresponding geological problems. |
