AbstractDomestic understanding of the causes and meanings of adakite has been debated for 20 years. Twenty years of research shows that the adakite is related to the high pressure background and can be raised into theory. Although there are still many problems about the formation and evolution of the adakite and there is still a heated debate about the adakite, these do not prevent the gradual formation and improvement of the adakitic theory. "The formation of adakite is related to the high pressure background" has proven to be an approximate correct theory. The author emphasizes that the characteristics of enrichment of Sr and depletion of Yb of adakite cannot be explained by conventional geochemical methods, and can only be explained by the theory of residual phase theory, indicating adakite and eclogites (which are eclogites, not garnets) are in balance. One important reason why adakitic theory can be called theory is that it has scientific foresight. The three prophecies that this paper proposes about adakitic theory are : (1) adakite does not coexist with Nanling type granite; (2) C-type adakite is formed in plateau and mountains; (3) adakite is related to gold and copper mineralization. The author welcomes global scientists to test the above three predictions. This article also re-proposed the "Eastern China Plateau" issue, pointing out that there have been a lot of plateaus and mountains that have disappeared at home and abroad. How to restore it and identify it, there are no ready-made examples, methods and ideas in foreign countries. The proposal of "Eastern China Plateau" has certain basis and is worthy of further study. This may open up a new direction for scientific research. This paper proposes to deploy regional and strategic prospecting work based on adakitic theory to carry out global and national surveys of medium-acid rock. This paper focuses on identifying the temporal and spatial distribution of adakite and Nanling type granite, and divides the area of crustal thickening and crustal thinning. Gold and copper prospecting work is carried out in the adakite development area and tungsten-tin prospecting work is carried out in the Nanling type granite development area.
