As one of the most important copper minerals, bornite extensively occurs in the Jiama Cu-polymetallic deposit. The research on the detachable portion of bornite ore and the formation conditions of gladite ore in this ore deposit shows that bornite ores were mainly formed in the medium-high temperature phase(225 ℃～450 ℃), with a few formed in the medium temperature stage (175 ℃～225 ℃) in the Jiama copper polymetallic deposit. A study of sulfur isotopic composition of copper minerals shows that sulfur was mainly derived from magmatic sources in this ore deposit. Mineralogical studies of bornites have confirmed that the formation of the Jiama copper polymetallic deposit was related to Miocene magmatic activity rather than to SEDEX held by previous researchers.
