The Shanggong gold deposit is a typical tectonic altered rock type gold deposit occuring in the Xionger terrane, southern margin of the North China craton. The isotopic data about this deposit are systematically analysed and comprehensively summarized, and some new understanding about the source of ore-forming material and ore-forming fluid are achieved. The D-O-C isotopic system shows that, the ore-fluid came neither from the Yanshanian magmatic hydrothermal solution nor from the devolatilization of the Taihua Group, Guandaokou Group and Luanchuan Group, but from mantle or mantle source magma, and it evolved to meteoric water in the metallogenic course. The S-Pb-Sr isotope ratios imply the ore-forming materials were derived from mixture of the crust and mantle, the mantle and Taihua Group may both contributed partial metallogenic materials. In the Indochina period, as a result of the collision of the Yangtze and North China plates, strong interaction between the crust and upper mantle took place, meanwhile the deep seated fluid transported upward, it was under this tectonic background that the Shanggong gold deposit formed.
