Ｓ、Ｐｂ、Ｃ、Ｏ和Ｈ同位素研究表明，安家营子矿田金矿成矿物质主要来自深部岩浆源，成矿流体为再平衡岩浆水．与金矿有关的安家营子二长花岗岩体为下地壳重熔成因，属金铜系列花岗岩类．金矿成矿年龄为１２０～１３０Ｍａ．
S, Pb, C, O and H isotope studies show that the gold deposits in the Anyijingyingzi orefield are mainly derived from the deep magmatic source and the ore-forming fluids are the re-equilibrated magmatic water. Related to the gold-bearing Anjiyingzi granite body is the cause of the lower crust remelting, is a bronze series of granite. Gold mineralization age of 120 ~ 130Ma.
