| 摘 要： | 文章在分析江川-建水地区区域地质背景和铀矿化特征的基础上，对矿体空间定位、含矿主岩、围岩蚀变、矿体形态等进行了详细研究，提出该区铀成矿主要受沉积建造和断裂构造控制的观点，并认为该区铀矿化与中上元古界不整合面有关。作者在深入分析江川-建水地区的铀成矿条件之后，提出了下一步找矿工作的方向。

| Abstract: | Based on the analysis of regional geological setting and uranium mineralization in Jiangehuan- Jianshui area, this paper makes a detail study on the host rock, shapes and location of orebody, and proposes that the uranium metallization are controlled by sedimental formations and fracture structures. The mineralization is believed to be related to the unconformity between Middle and Upper Proterozoic. After deeply analysising uranium metallogenic condition of Jiangchuang-Jiangshui area, the author has put forward the oreintation for next prospecting. |
