【Abstract】 By radioactivlty geophys1cal surveying, the authors have got the geochemical data required in geological research and used them to divide the lithodemic units of magmatic rocks and to set up the rank systems in order to solve the subdivision and assignments of the intrusive bodles which belong to different sequences. This simple. convenient and feasible method opens up a new way for large-scale geologlcal mapplng and for dividing the geological mapping units.更多还原
