摘要
对柯树背岩体的岩石化学、稀土元素、微量元素及铀金成矿元素进行了系统的研究,研究结果表明:柯树背岩体F9大断裂(鹰潭—安远深大断裂)以东部分(东体)与F9大断裂以西部分(西体)在稀土分布模式、微量元素、铀金成矿元素及矿化特征上存在很大的差别,东体与寨背岩体类似,为同熔系列花岗岩,对铀成矿不利;西体为重熔再生岩浆成因的改造型花岗岩,对铀成矿有利,具有良好的成矿远景。
In this paper, element geochemical characteristics and its ore-forming significance of Keshubei rock mass has been detailed studied. The results show that the western and eastern parts of rock mass has obvious differences in REE patterns, trace element, U-Au ore-forming element and mineralization characteristics. The eastern part of rock mass is similar to Zhaibei rock mass, being regarded as syntectic series granites, and has disadvantageous to U ore-forming. Whereas the western part of rock mass is regarded as reformed series granites and has advantageous for U mineralization.
