Abstract 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.
