  • 摘要: 针对广西晚二叠世聚煤盆地中锂、镓元素地球化学异常问题,选取扶绥和贤按两个典型晚二叠世煤田,通过系统取样测试,研究煤系中锂、镓丰度,并结合成矿地质背景,分析煤中锂、镓的富集控制因素。结果表明:研究区锂和镓均有一定的工业前景,扶绥煤田锂和镓的平均丰度分别为83.5 μg/g和30.8 μg/g;贤按煤田锂、镓丰度分别为199.1 μg/g和33.4 μg/g。锂主要富集于合山组底部K1煤层、炭质泥岩及铝土岩段,而镓在合山组底部各岩性中的丰度并无明显差异。云开古陆及周边中酸性火山岩是锂、镓物质的基础来源,合山组底部高铝沉积岩系可能是合山组K1煤层中锂、镓的直接物源。镓元素在各岩体之间的迁移比较活跃,其物源区的含量水平起主导作用,而锂元素的富集除了受控于物源外,沉积环境及后期地质作用的影响更为明显。研究成果为广西煤系中锂、镓资源的勘查预测及其综合利用提供科学依据。
