| Abstract: | The analysis and prospect on development trends of instrument, technique of data processing, theory and method, applications of gravity and magnetic prospecting in the 21st century are discussed here. In order to improve capability of data acquisition, airborne gravity scalar ,vector and gradient surveys, airborne full gradient magnetic surveys, three component magnetic surveys will be carried out. The satellite gravity and magnetic surveys will be carried out, so satellite data will be used for combined airborne and ground surveys data to study Earth's structure and tectonics. The technique for high precision data processing will be developed, such as the extraction of weak signal, the determination of anomalies resulted from sources at different depths, the reduction to the pole at low latitude with varying magnetic inclinations, the continuation of potential field to curved surface. The techniques of multi parameter 3D inversion and its visualization in complicated conditions and rapid auto inversion will be studied. The multi parameters of magnetic properties will find their new applications. The full use of magnetic prospecting will be made in environment pollution investigations, and its new applications will be open up. |
