摘　　要：Objective Lop Nur is one of the world’s largest Quaternary salt lakes and is currently a playa. In this lake, unique giant glauberite deposits occur, of which the intercrystalline pores host super-large liquid potash deposits. Recently, it has been thought that the potassium-rich brine was formed when the enormous quantity of glauberite deposited. To clarify this issue 14 C dating for brine is used to provide new evidence of chronology illustrating the relationship of potassium-rich brine with the host glauberite rock and improve our understanding of the formation mechanism of the brine in Lop Nur playa.
