摘　　要：甘肃桦树为铁铜矿床地质、同位素地球化学、包裹体地球化学、同位素年代学研究表明，该矿床形成于震旦纪裂陷海盆环境，矿床成因属典型的热水沉积成矿。Huashugou Fe-Cu deposit is located in the western part of Northern Qilian Caledonides. The deposit was formed in Sinian rift sea-basin system. According to deposit geology, geochemical study of S, Pb,C, O isotopes, fluid inclusion and isotope chronology, the metallogenic material is related to a deep fluid; themetallogenic fluid is a thermal water of acid and reduction ; the Fe-Cu ore bed is a type of syngenetic sedimentry. The main metallogenic process is submarine exhalation-sedimentry.
