Abstract: In order to investigate the radioactive geophysical features, uranium metallogenetic geological setting and metallogenetic conditions at Haizishan area, the ground total gamma survey and geology-gamma spectrometric profile survey were conducted. The radioactive background of Haizishan area was preliminarily cognized through the ground total gamma survey and the radioactive features were identified. The anomaly properties of Late Yanshan granites were roughly confirmed through geology - gamma spectrometric profile survey, and the detailed statistical analysis was done for radionuclide contents of each major lithostratigraphy. The results show that Late Yanshan granites in this area have higher total gamma background value, and the distribution of total gamma anomaly is almost consistent with Late Yanshan granites. The uranium background value of the granites is higher, showing the uranium sources are favorable in this area. There is Chaqingka hot-spring anomaly in the western periphery of Haizishan area, which is in connection with the northwest fault. The sinter on the ground has very high total gamma measurement value, and the uranium - thorium anomaly occurrence is shown through gamma spectrometric survey. According to the geological and radiometric properties of Chaqingka hot-spring anomaly, combined with the uranium metallogenetic geological setting and metallogenetic conditions in the area, the authors identified that the potential source of uranium is bearing fluids containing uranium or the uranium is likely to be abundant in deep Late Yanshan granites. The uranium is migrated to deposit and enrich at the surface, which provides a prospecting target for further uranium exploration.
