| 摘 要： | 利用最新的航空伽马能谱数据,分析了宁安盆地以及501铀矿床的航空伽马能谱特征。并利用铀转换参数(初始铀、活性铀、铀迁移系数)分析了本区的铀源条件,结合盆地基底、构造、岩相岩性、水文地质等成矿条件进行了铀成矿分析和远景预测。最终预测了3处铀成矿远景区段,对本区进一步找矿具有指导意义。

| Abstract: | Using the latest airborne gamma ray spectrum data,airborne gamma ray spectrum characteristics around Ning'an Basin and 501 uranium deposit were analyzed at first in this paper.Uranium transformation parameters (initial uranium,active uranium and uranium migration coefficient) was then used to analyze the uranium source condition of the region.Prospect of uranium mineralization was forecasted with the metallogenic conditions of basin basement,structure,lithofacies and lithology,hydrology geology and finally 3 favorable areas of uranium mineralization are selected finally for further prospecting in this area. |
