The Seashore And Inland Brines Typical Distribution Areas Late Quaternary Environmental Evolution And The Brines Formation

Firstly, I summarize the quaternary seashore underground brine characters, geology and physiognomy in south Laizhou Bay in this paper. Owning to the previous studies on the quaternary environmental changes around Bohai Sea and Core-E sediment stratum materials in the Laizhou Bay, I master the late Quaternary environmental evolution trend preliminary.By through analyzing the quaternary brine chemical Characteristics in Laizhou Bay and contrasting the chemical composition curve in evaporation and freezing processes, I think the Laizhou Bay seashore underground quaternary brine is formed by evaporation, combining the previous study on the quaternary environmental evolution in this area, I consider that the Late Quaternary alternating wet and dry climate is the climatic factor in seawater evaporation process, the Sedimentary facies changes in the process of transgression and regression conserves the concentrated ancient seawater.At the foundation of the previous materials, recapitulating the Charham Salt Lake brine and the geology and physiognomy in this area. By through combining the Charham Salt Lake basin formation process and the quaternary environmental evolution in this area, discussing the formation of the Charham Salt Lake brine. Finally, from three aspects including the geographical environment, the source of salt and the climate conditions, studying the influencing factors in the formation processes of the Laizhou Bay quaternary seashore underground brine and the Charham Salt Lake brine.
