With the rapid development of China's national economy,the contradiction between mineral resources requirements and support capabilities have become increasingly prominent.The metal ore exploration has become an important task of geological work.Increasing the depth of exploration,so also will increase the difficulty of prospecting,geophysical prospecting techniques which provide for the development of space.This paper summer arises the technique of high precision aeromagnetic,airborne electromagnetic measurement techniques,airborne radioactivity measurement techniques,airborne gravity measurement technology,ground electromagnetic measurement techniques,borehole geophysical measurement technique,the metal mining seismic exploration technology,portable seismic array and deep seismic detection techniques,etc.,summarizes a more comprehensive exposition of these methods and application of technology.These methods and techniques are currently effective mineral exploration geophysical methods and techniques developed in recent years,and of a far-ranging application prospect in a new round of mineral exploration.However,multiple explanations of geophysical exploration results have long imposed difficulty on application of geophysical methods.So how to choose and employ these methods and how to take full use of their own advantages become particularly important.This overview just summarized achievements made in methods and techniques,basic principles,technical characteristics,application scope and conditions,case study and results,in hope of giving some guidance for metallic ore exploration.
