摘　　要：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．Study on the S,Pb,C,O,H and Sr isotopes shows that:(1)the oreforming substances of Anjiayingzi gold field were mianly derived from deep magmatic source;(2)the oreforming fluid was reequilibrated magmatic water;and(3)Anjiayingzi adamellite mass related　to gold deposits was derived from remelting lower crust rocks,it should belong to AuCu series granitoidThe minerogenetic ages of gold deposits are 120～130Ma
