| Abstract: | Uranium mineralizations in Preterozoic Era in the middle-south partion of Kangdian area, were subdivited into four main types and seven subtypes in this paper. The author sumerized the general features of uranium mineralizations in Preterozoic Era, and pointed out that uranium mineralizations (960-600Ma) were formed in Jingning-Chengjang tectonic period, which is consistent with the reform-enrichmental period of Copper mineralization in the same strata. The metellogenic prospects of unconformity-type uranium deposits were discussed. It is a posible target to searching for unconformity-type of uranium near the unconformity of middle-upper Preterozoic in the area. |
