富锂盐湖中锂的物质来源和流体来源

锂资源是新技术、民用和军工行业的重要原料,全球富锂盐湖多分布在板块俯冲带和碰撞带以及板块转换带,卤水中的锂资源量占全球锂资源总量的80%。富锂盐湖中的锂主要来自于深部和浅部的水-岩作用、早期的含盐岩系以及岩浆作用,其次是盆地周围岩石的风化以及大气来源。富锂盐湖流体主要来源是大气降水、地表水、地下水、再循环卤水和岩浆水以及其它流体。地表水和地下水为富锂盐湖中锂的重要来源,其次是岩浆水和再循环卤水。岩浆作用对于富锂盐湖的形成至关重要,其不仅直接为富锂盐湖带来了成矿物质和成矿流体,还为其中的水—岩反应提供了热源。不过,幔源组成对于富锂盐湖的贡献度还需要作进一步研究。

Material sources and fluid sources of lithium-rich lithium salt lake

:Lithium is an important raw material for new technology, civil and military industry. The brine lithium resources comprise 80% in the whole world, and lithiumrich salt lakes are mainly distributed in plate subduction zones, collision zones and plate transformation zones. The sources of lithium in lithiumrich salt lakes are mainly dominated by deep and shallow waterrock interactions, early saltbearing formation and magmatism, secondarily are the weathering of the rock around the lakes and atmospheric input. The lithiumrich salt lakes fluids can come from atmospheric precipitation, surface water, groundwater, recycling brine, magmatic water, etc., of which the surface water and groundwater with the largest contribution, following by recycling of brine and magmatic water. Magmatism plays a crucial role in lithiumrich salt lakes forming, which not only brings the oreforming elements and fluids, but also provides the heat source for the waterrock reaction. However, further studies about how the mantle source fluid being added into the lithiumrich salt lakes were needed.
