| Abstract: | uranium deposit, a typical volcanic type deposit, can be divided into two kinds of mineralization,i.e.Fe-U type and U-Mo type.The main host rock is trachyte with distinctive pockmark structure. The deposit's metallogenic mechanism has been discussed and metallogenic model has been established on the basis of its geochemical features of petrochemistry ,paragenetic and accompanying elements,rare-earth elements,stable isotope,metallogenic temperature and age . |

| Keywords: | volcanic uranium deposit geochemical features mechanism of metallogency metallogenic geochemical model |
