摘要:
泥岩的沉积序列和地球化学特征包含大量地质信息,广泛应用于沉积学及其物源分析等?豫西巩义地区上石炭统本溪组富集锂资源,但对于锂资源的来源?沉积条件等控制因素及赋存的矿物等不明确?基于野外露头等资料,综合分析豫西巩义地区上石炭统本溪组主量?微量和稀土元素特征,阐明本溪组锂富集特征,探讨本溪组的源岩?岩石风化程度?沉积物分选状况和古环境特征,进而分析本溪组锂富集的成因?结果表明:本溪组锂资源丰富,主要富集在泥岩中(Li平均质量分数为1487×10-6),而铝土矿Li含量较低;沉积序列表明,本溪组主要以细粒沉积物为主,形成于潟湖环境;B/Ga?Sr/Cu值等参数表明沉积时期海水为微咸水,气候条件为温湿—干热气候,处于还原环境;微量和稀土元素等综合图解分析表明,物源区母岩以长英质岩浆岩为主,灰岩和泥岩等是次要物源,化学蚀变指数?风化指数参数及图解表明源岩遭受强烈的风化作用,经历沉积再旋回作用?本溪组富锂泥岩的物源?沉积特征等综合分析表明,锂资源的富集与泥岩中高岭石?绿泥石等黏土矿物关系密切,本溪组源岩为锂富集提供物质基础,沉积物的再旋回过程?沉积环境等沉积特征影响锂资源的富集?
