摘　　要：根据黔西北地区铅锌(铁)矿,基于地球物理场中的物性响应特征及固有物理性质,及矿床分布与物探异常的空间关系,建议今后黔西北地区物探找矿工作,要大力提倡综合方法找矿,围绕①以区域重磁资料为基础背景研究平台-建立找矿靶区,②以开展1∶5万地面高精度磁测扫面为常规研究手段-确定找矿选区,③以1∶1万或1∶5千及更大比例尺的重磁电联合探查-发现有用异常,④对有价值异常综合信息评价及重要地段加密采样测量与有效工程验证-摸清异常原因等四个层面进行。According to the correspondent eigenvector and intrinsic physical proper base on geophysical field in the lead-zinc deposit in northwest Guizhou,the relation of deposit distribution and geophysical prospecting abnormality,it＇s suggested that the comprehensible method should be strengthened in the future geophysical prospecting.The target area should be set up which the basic studying background is the regional gravity –magnetic information.Ensure the elected area by the general method of 1∶50 000 surface high accuracy magnetic survey reconnaissance.Find the abnormality by gravity,magnetism and electricity combined method of 1∶10 000,1∶5000 or bigger scale.Access the valuable abnormality information;resampling test and effective engineering verification in the important area;find out the reason of abnormality.
