摘　　要：莱西市萌山地区位于胶东半岛金矿集区西北部,为提高萌山地区找矿认识并为胶西北等地区提供指导,于区内开展了激发极化法的应用研究,取得主要成果如下:认为激发极化法在区内圈定激电异常区、获取电性结构分布方面优势明显,在甄别含石墨地层、区分矿致和非矿致异常方面存在问题,并分别提出增设复电阻率法、土壤地球化学测量的改良建议;提出下一步金矿勘查重点方向可能为IP1、IP5重点激电异常区和深部,应围绕这2点加强物化探及地质工作研究程度。本文深入分析了激发极化法在萌山地区金矿勘查中的技术优势和存在弊端,提出了该区下一步的金矿勘查重点方向,对胶西北地区及胶东集矿区开展后续金矿找矿工作具有重要意义。Mengshan area of Laixi City is located in the northwestern part of Jiaodong Peninsula gold mining district.In order to improve the understanding of mineral prospecting in Mengshan area and to provide guidance for the northwest Jiaodong Peninsula and other areas,this paper carried out the application research on induced polarization method in the area,and achieved the main results as follows:It is considered that the induced polarization method has obvious advantages in circling the excitation anomaly area and obtaining the distribution of electrical structure in the area,and there are problems in screening graphite-bearing strata and distinguishing between mineralized and non-mineralized anomalies,and it is proposed to add the complex resistivity method and geochemical soil survey for improvement respectively.It is proposed that the next key direction of the gold mine exploration may be the key excitation anomaly area and the deep part of the IP1 and IP5,and the research degree of physical and chemical exploration and geological work should be strengthened around the 2 points.This paper deeply analyzes the technical advantages and disadvantages of the induced polarization method in the gold mine exploration in Mengshan area,and proposed the next key direction of gold exploration in the area,which is of great significance for the follow-up gold mine searching work in the northwestern Jiaodong Peninsula and Jiaodong mining district.
