摘要
This paper has systematically discussed geological characteristics and ore-forming processes of Quaternary littoral facies underground brine, including its burial conditions and aerial distribution. The results indicate that the water-bearing layer of shadow underground brine is No.1 layer existing in Holocene, whereas the water-bearing layers of pressurized underground brine are No.1-4 layers in Pleistocene. The underground brine is a complex water-salt system derived from seawater and subjected to intense evaporation and concentration in Quaternary sediments.
