TY - RPRT TI - Application of gas geochemistry in the search for different types of uranium deposits. Final report for the period 15 November 1991 - 15 March 1994 AB - This paper presents the study of primary and secondary gas halo and application in the search for different types of uranium deposits in China. Through measuring Rn, CO{sub 2}, O{sub 2} and Hg in various deposits of geographical and climatic conditions for the gas geochemical survey. Three comprehensive measuring methods of CO{sub 2}, Rn and 0{sub 2} were thought to be optimum for gas geochemical exploration because of its portability, rapidity, low cost, simple operation and limited interference. Our experimental data can be briefly summarized that higher concentration of CO{sub 2}, Rn and lower concentration of secondary halo in soil show blinded deposits. Our project have finished the study of thermal emanating gas in soil and rock. The methods were confirmed by known deposits and can be used in uranium exploration or environment investigation. 4 refs, 23 figs, 26 tabs.
