| 摘 要： | Presented in this paper are some primary data on the well temperature, stratigraphical level and thickness of uranium mineralization in a certain uranium, ore deposit.Taking these data as the parameters.for the temperatures, pressures and geochemical conditions of uranium mineralization under ideal geological conditions, which constitute a finite variable series, in conjunction with the catastrophe theory developed by Rene Thorn (1968), we have proposed a swallow-tail model fitting to uranium mineralization.This model provide insights into the mechanism of uranium mineralization.The results of our study show that the uranium mineralizing process is a discontinuous or catastrophic event. Temperatures and pressures are considered important thermodynamic trap conditions which control the distribution pattern of uranium mineralization, and the principle of correspondence between the temperature and pressure conditions for uranium mineralization has been also derived, Geological bodies of minerogenetic importance serve as favourable geochemical media for capturing ore-forming materials. Uranium mineralization of industrial importance depends on a delicate coupling between temperature, prassure, and geechemical condition. The spurs of uranium mineralization in the model constitute the surface K, referred to as the surface of mineralizing enrichment on which minerogenetic dominance is expected.The model provides quantiatitively clnes to the process of uranium mineralization,i.e.,a process from quantitative change to qualitative change.
