摘要
康滇地轴是中国重要的多金属成矿带之一,而铀矿地质工作一直未能取得突破性进展。本文阐述了江川—建水地区与不整合面有关的铀矿化特征及铀成矿模式。认为该区存在有与中新元古界不整合面有关的铀矿成矿条件,具有较大的找矿潜力,指出下一步找矿的重点部位应放在切穿中新元古界不整合面的断裂构造蚀变带上。
The Kangdian axis is one of important polymetallic mineralization belts in China, but geological investigation for uranium ores has not made breakthrough progress. This paper makes an approach to the characteristics and genetic model for uranium mineralization related to the unconformity between Mesoproterozoic and Neoproterozoic in the Jianchuan-Jianshui area, south section of the Kangdian axis. The study indicates fracture-alteration zones cutting the unconformity is of U-searchingh promising.
