摘　　要：通过岩石学、岩石化学、微量元素、稀土元素等研究确定了达巴特铜矿与一火山机构密切相关 ,该火山机构由火山管道相的流纹质熔岩和次花岗斑岩组成 ,铜矿化主要产于火山管道两侧 ,并指出应在火山管道南侧下盘寻找隐伏铜矿体。By studying the petrology, petrochemistry, trace elements, rare earth elements, etc, the authors have ascertained that Dabate copper ore deposit is closely related with a volcanic edifice. The volcanic edifice is composed of rhyolitic lava, rhyolitic welded tuffs and granitic porphyries. The copper ore bodies occur on both sides of the conduit. And the authors suggest that the blind copper ore bodies may underlie the south side of the volcanic edifice.
