Symposium on some problems in geoscience deployment and countermeasure was convened by the Geoscience Division of Chinese Academy in Beijing in November 22~24, 1990.Some important basis problems of geoscience which have potential important significance to geoscience development were digcussed at the symposium, they are:
    1. comparative planetology;
    2. deep ocean researches;
    3. deep Earth interior studies;
    4. present tectonic motion and dynamics;
    5. microphysical-chemical problems in minerals and in petrogenesis, metallogenesis;
    6. low-temperature geochemistry;
    7. palaeoenvironment and palaeoclimatology of the Earth;
    8. living beings evolution and the origin and evolution of human beings;
    9. ocean circulation and ocean dynamics;
    10. studies of thd basic theory of atmospheric physical and dynamic processes;
    11. the study of the dynamic change of the cryosphere;
    I2. the general process of Global climate system;
    13. the interaction between Geosphere and Biosphere;
    14. Earth fluid dynamics and- geoscience numerical simulation;
    15. the basic research of remote sensing in geoscience;
    16. the modulation study of Earth crust and man-Earth system.
