摘要
文章阐述了302铀矿床的围岩蚀变特征,重点分析了围岩蚀变分带及其地球化学特征,认为该矿床近矿围岩蚀变具有明显的水平分带性,垂向上也有一定的变化规律。根据蚀变带U、Co、Cr等元素含量的增加,指出铀成矿热液具有深源性;根据不同标高蚀变带元素组合特征,认为该矿床目前的开采部位还处于矿床中部,推测深部有较大的找矿前景。
The alteration characteristics in uranium deposit No.302 was elaborated,the zonation and the geochemistry characteristics was analysed in detail.It was found that near-ore wallrock alteration is with zonation in horizon and also some patterns in the vertical.It was proposed that content increases of U,Co,Cr in alteration rocks may indicate a deep origin of hydrothermal uranium mineralization.From the elements combination characteristics of the alteration zone at different level of the deposit,the exploration is still within the middle of the deposit,and therefore there is great space for deep exploration.
