Abstract

Quaternary underground brine in the littoral plain region of the Bohai coast is new type littoral facies evaporation ore deposit in liquid state. This model of “littorally-forming brine” is based on study of the distribution, depositional environment, forming/storing process, and genesis of underground brine in the coast of Laizhou Bay. Essential conditions for genesis of brine are arid and semiarid climate, abundant sources of ancient seawater, and geological and geomorphological environment of wide tidal beach along a coast. The process of underground brine genesis may be: seawater/tidal beach » evaporation and concentration » seeping and accumulation » brine/tidal beach » burial (evolution of the sea-land)» underground brine.

Underground brine is characterized by high content of chemical elements, shallow burial depth and easy exploitation. The process of extracting salt from underground brine present in the tidal flat is incomparably superior to that of producing salt from seawater, and has brough great economic benefits to the coastal areas of Laizhou Bay, Shandong Province.
