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.

The dissertation is supported by China National Nuclear Corporation project, studying“The uranium resources potential evaluation of Kangdian Axis”and“The depth portion drilling verification of 306 uranium in Jiangchuan of in South Section of Kangdian Axis”as a backing.
