In the Yinshan—Dexing district in northeast Jiangxi, the faults, oredeposits ,o rebodies and element zones demonstrate a series of nonlinearity and complexity . The fractal of the faults system is 166, close to the fractality of the f aults induced by earthquakes all over the world. The regional zoning of the geo chemical elements， ore veins and ore deposits own a selfsimilarity. The ductile shear zone system in the northeast of Jiangxi has a typical 3D “quasiMenger sponge” structure. In the Yinshan mining area, the ore veins have the conventional CuPbZnAg zoning. However, their onehosting structure systems have differe nt fractal characteristics and display the complexity of “the totality is not the sum of parts”. There are two overlapping metallogenetic subsystems in the same space.All of these characters are of great significance to mineral resource prognosis in this district
