| Abstract: | This belt has 5 super large volcanic hydrothermal vein type uranium deposits and 6 large size volcanic hydrothermal vein type uranium deposits with a total reserve of 330 000 t and holds an important position in the hydrothermal vein type uranium resources of the world.The study shows that the metallogenesis of the uranium deposits in this metallogenic belt has features of abruptness on time.The metallogenic epoches are concentrated in early Cretaceous,and uranium metallization are controlled by a united Mesozoic continental taphrogenic volcano magmatic activity.The metallogenic media are moderate low temperature volcanic hydrothermal solutions originated from the mixing of deep volcano magmatic water,meteroric water and metamorphic water.The ore forming materials are mainly derived from Mesozoic deep enrichment type magmatic source. |
