At the same time, British researcher G.F. Dai Weixun first put forward the theory of brine mineralization in 1964. He believes that all kinds of metal deposits formed in unrealistic environment in the past (for example, abnormal atmosphere, special volcanic eruption, rivers with strange chemical composition, etc.). According to the current experience, it may be formed by underground salt water mixed or unmixed with magmatic water. Later, D.E. White (1968), K.C. Dunham (1966, 1970), T.C. Cao Cenijie (1972) and others all studied on the basis of a large number of actual data. K.C. Dunham also suggested that deep groundwater, especially sealed ancient seawater and oilfield brine, may play an important role in mineralization. Geologists in the Soviet Union (former Soviet Union), the United States and other countries have provided a lot of evidence to support the above theory.
W.S.Fyfe published a monograph "Fluid in the Crust" in 1978, mainly discussing the significance of fluid in metamorphism, tectonism and chemical migration.
As early as A.D. 147, China drilled a natural gas well in Qionglai, Sichuan Basin, and in A.D. 280, he produced gas in Zigong artesian well in southern Sichuan to extract brine and boiled salt. The high salinity pore fissure water in the upper Triassic sandstone-mudstone sedimentary system is as famous as gas production. After the founding of New China, large-scale exploration and development of deep brine and hot water, especially oil and gas fields, accumulated a lot of geological and hydrogeological data and published many guiding research works. However, in the decade after the mid-1960s, the research work was almost at a standstill. Since the mid-1970s, domestic researchers have begun to study the paleohydrogeology of deep brine, hot water, oil and gas fields and metal deposits. , and published several works in succession. According to incomplete statistics, there are monographs published by Wang Yunpu, Wang Yunpu, Wang Yunpu and Wang Xu. (1982) "Formation of deep brine and its research methods", Wang Yunpu, Zhao Baozhong, Zhang Jinlai, etc. (1987) "Paleohydrogeology and Hydrogeochemistry of Oilfield", Shen, Wang Yunpu, Wen Dongguang, Wang Min.

Geological fluid is the most active material component in the sedimentary system, and it is a powerful geological force that actively transfers energy and materials in the process of geological history and participates in various geological processes and mineralization. Water is the most widely distributed and abundant component in geological fluid, which can be called ubiquitous and ubiquitous. It goes without saying that the research on the mineralization and mineralization law of liquid, gaseous and solid metallic and nonmetallic deposits will focus on the circulation law of ancient water activities in the sedimentary system and take it as the basic or core research content, which will effectively promote and promote the progress of paleohydrogeology. Geological fluid has become one of the frontier fields and research hotspots in contemporary earth science research.
New data and achievements have been obtained in the study of geological fluids abroad. However, in recent years, most domestic hydrogeologists have devoted themselves to short-scale shallow water and environmental geology research, and the number of subjects, funds and researchers involved in long-scale deep water research has decreased compared with the past, and the research work has lagged behind that of foreign countries.
