Abstract:Abstract: The district of concentrated metallogenesis is an area where mineral deposits are densely concentrated in a certain range. In the area superlarge, large, median, and small deposits, occurrences and mineralization of different minerals or different types are distributed in a certain space. There is a certain interrelation in spatial and temporal distribution of the mineral deposits in a district of concentrated metallogenesis. The district of concentrated metallogenesis is an important base of mineral resources and is of great significance to supplying mineral resources necessary for economic development. Meanwhile, the district of concentrated metallogenesis is also an important exploration area with potential mineral resources and districts of concentrated metallogenesis where many old mines are located are still important prospect areas of China. To strengthen the study and exploration assessment of districts of concentrated metallogenesis is an important way for increasing mineral reserves and has great significance for alleviating the deficiency of mineral resources in old mines.
