摘　　要：了解勘查区的地球物理特征并据此开展物探方法试验性工作,是合理选择该区域适当的物探工作方法的前提,以达到增强找矿效果、降低勘查成本的目的。笔者在老挝丰沙里新寨铜矿开展了激电中梯、高频大地电磁试验工作,激电中梯在已知矿体上表现为明显的高极化率特征,高频大地电磁测深工作根据电阻率差异对深部岩层界线进行了划分。其试验效果可为周边开展物探工作提供参考依据。Understand the geophysical characteristics of exploration area and carrying out the experimental work of geophysical methods is the premise of selection of geophysical prospecting method suitable for this area, which is conductive to enhancing the prospecting effect and reducing exploration cost. Induced polarization intermediate gradient survey and HMT sounding had been carried through. The induced polarization anomaly is character of high in Apparent polarizability which is consistent property of known ore-body. Based on the impedance difference among different rocks, lithologies can be classified according to the HMT results. The object of this paper is to provide valuable information for choosing suitable geophysical prospecting method in adjacent regions.
