Abstract: A strategic overview is presented on the adaptation of geophysics to the present situation of geological exploration in which decp-burried deposits are principally concerned in China. To meet this demand it is imperative that the entire exploration capacity reach the depth of 300-500 meters with integrated applications of various geophysical methods and techniques. Meanwhile, based on the improvement of three dimensional whole-space geophysical exploration capacity, high-advanced techniques with good resolution and great exploration depth should be primarily developed in order to renew the conventional techniques and stimulate the development of metallic resource exploration. The overall exploration capacity is thus expected to be up to 1.5-2 km by the advent of the 21st century.The authors believe that whether the problems involved in metallic resource exploration can be solved or not will eventually be determined by the correct recognization of the relationship between metallic resources and the deep structure of the crust and the uppcr-mantal, so MT surveys should be carried out to investigate the roots of great mines.
