This paper introduces some applications of two types of apparatus named CD 3 computerized ground γ ray spectrometry and CD 1 α cup measurement to the study of the mineral formation conditions in the middle southern section of Kang Dian Axis.

This paper systematically expounds abundance of uranium of granitoids with γ-energy spectrum and fundamental features of granitoids-type uranium mineralization in Kangdian axis, on the basis of correlation with U-bearing granitoids in south China, perspective of a search for franitoids-hosted uranium ores in Kangdian axis is discussed.

Based on the geological features of gold mineralization in Shimian-Huili section of Kangdian axis,this paper investigates the isotopic ages,isotopes of hydrogen,oxygen,carbon,sul-fur and lead,suggestes the classification of ore-forming fluids,the sources of carbon,sulfur,lead as well as gold.
