| Abstract: | In this paper, a review has first been made as to the achievements scored during recent years in such aspects as aerogeophysical prospecting, regional gravity survey, geophysical prospecting for metallic and nonmetallic ore deposits as well as for coal basin, hydrologic and engineering geophysical exploration, and geophysical survey for information at great depths, with an enumeration of geologic results achieved and methods and instruments newlyadded for utilization, then some tentative ideas have been put forward concerning the future work, arguing that geophysical exploration should be advanced to a new stage to achieve four objectives; discussion is also given on some important subjects, e. g., to conduct the second-generation aerogeophysical work; to extend the regional gravity prospecting to complicated areas; to perform 1:50,000 integrated geophysical survey as an important component part of the geophysical prospecting work; to speed up the geophysical work in aspects of hydrologic engineering prospecting and geothermal prospecting; to enable geophysical prospecting for metallic and nonmetallic deposits to tackle increasingly complicated and variable problems; to further strengthen geophysical prospecting for coal basins; and to work out a long-term plan of deep-seated geophysical survey for systematical work. At the end of the paper, some expectations have been made for improving techniques and instruments. |
