As to age_dating methods,the author recommends that single Uranium_bearing mineral U_Pb method is to be adopted ,for the precambrian gold deposits but for the Phanerozoic one the 40 Ar/ 39 Ar,K_Ar and Rb_Sr isochron methods are recomended.

• 测年方法上，应采用单颗粒含铀矿物U－Pb法，而40Ar/39Ar、K－Ar法和Rb－Sr等时线法仅适于测定显生宙形成的金矿床
