岩石学、岩石化学、微量元素、稀土元素、稳定同位素（Ｓｒ、Ｐｂ、Ｏ、Ｈ和Ｃ等）和同位素年代学研究表明，安家营子金矿田与金矿有关的二长花岗岩小侵入体为下地壳基性岩石重熔成因，属Ⅰ型花岗岩类（或磁铁矿系列花岗岩），为金矿的同源岩和矿源岩。岩体以易活化金丰度高为突出特征。同源花岗岩源岩的含金性对斑岩金矿床的Ａｕ－Ｃｕ匹配有重要影响。 Petrology, petrochemistry, trace elements, rare earth elements, stable isotopes (Sr, Pb, O, H, C, etc.) and isotopic chronological studies show that the small gold intrusive granite intrusive For the lower crust basic rock remelting genesis, is a type of granite (or magnetite series of granite), gold ore source rock and source rock. The rock mass is characterized by the high abundance of activated gold. The gold content of homologous granite source rocks has an important influence on the Au-Cu matching of porphyry gold deposits.
