摘要
相山铀矿田邹家山工区 5 0m中段发现含铀凝灰岩 ,化学分析结果显示 ,这种凝灰岩铀矿石中铀含量达 7 1 3 % ;该矿石中绿泥石含量较高。笔者认为 ,在相山铀矿田中 ,花岗斑岩与凝灰岩接触部位应有富铀矿体存在。
At the -50 m level of Zoujiashan ore district,Xiangshan uranium ore field,uranium?bearing tuff was discovered.Chemical analysis indicates that uranium ores in such tuff may contain uranium up to 7 13%.Content of chlorite in such ores is high.Authors suggest that rich uranium ore bodies must exist at the contact between granite?porphyry and tuff at Xiangshan uranium ore field.
