小武当断陷红盆铀矿成矿潜力

小武当断陷红盆位于浰源岩体北部，该岩体位于大东山—贵东岩浆岩带东段，属南岭产铀岩体，二者呈断裂接触，断陷盆地位于该断裂带上盘。该处成矿地质条件与岩体上覆盆地亚类型铀矿床极为相似，从成矿背景、盆地类型、盆地年代、沉积环境、含铀建造等多方面与黄子洞矿床这一典型的岩体上覆盆地亚类铀矿床进行类比分析，认为岩体北部小武当断陷红盆深部具有较大的找矿潜力，为研究区新型铀矿床的勘探提供新的找矿方向和找矿思路。

Metallogenic potential of the uranium deposit in the red basin of Xiaowudang fault depression

The red basin of Xiaowudang fault depression is located in the northern part of the Liyuan rock mass that is in the eastern section of the Dadongshan-Guidong magmatic rock belt and falls into the Nanling uranium-producing rock mass. They are in fault contact. As the hanging wall of the fault zone, the metallogenic geological conditions of the Xiaowudang fault basin are very similar to the subtype uranium deposits in the overlying basins of the rock mass. Based on an analogy analysis of metallogenic setting, basin type, basin age, sedimentary environment, uranium bearing formation of the Huangzidong deposit, a typical subtype of uranium deposit in the overlying basin of the rock mass, it is believed that the deep part of the red basin of Xiaowudang fault depression in the northern part of the Liyuan rock mass has great prospecting potential. The paper provides new prospecting directions and ideas for exploring new types of uranium deposits in the study area.
