Abstract: By comparing Shuijingtun gold deposit with typical gold deposits in the same region on S-Pb-H-O isotopic geochemistry, the authors conclude that metallogenetic material was derived mainly from Shuijingtun structural stratigraphic unit. Archeozoic regional metamophism only resulted in initial enrichment of gold. Structural-magmatic activity in Indo-Chinese-early Yanshan epoch helped to bring about the main body of quartzveins. The inherited structural-magmatic activity in Yanshan epoch was the main factor of gold mineraliza-tion. Mineralizing fluid was mainly originated from magmatic water. It's defined that Shuijingtun gold deposit is of stratabound magmatic hydrotherm altype. Its metallogenic modle is established.
