摘要: 如何扩大和发展老的铀矿点(带)是当前铀矿找矿紧迫的任务之一。基于相山矿田大成矿的地质背景,本文论述了相山矿田梅峰山地区的地质特征,分析了该地区控矿地质因素及找矿前景。通过与同类型铀矿床在控矿因素、地质条件等方面进行对比,认为梅峰山地区与邻近的铀矿床处于同一地质构造单元,它们的成矿地质条件和控矿因素较相似,具有较好的找矿潜力,推覆体下隐伏的次火山岩体(次花岗斑岩)的变异部位是该区进一步的找矿方向。Abstract: One of the most important and urgent prospecting tasks is how to expand and develop the old uranium ore spots or ore zones. On the basis of the geological backgrounds of the Xiangshan ore field, the geological features, ore-controlling factors and prospecting potentials of the Meifengshan area are discussed in this paper. Comparison with the same type of uranium deposits in ore-controlling factors and geological conditions suggests that the Meifengshan area has the same tectonic units with the uranium deposits in adjacent areas and the similar metallogenic geological conditions and ore-controlling factors, indicating it is of good prospecting potential. It can be concluded that the variation positions of secondary volcanic rock mass or granitic porphyry hidden in nappes be future prospecting directions in this area.
