摘　　要：马关县曼家寨铜矿位于滇东南老君山花岗岩体,已发现的大多数矿体呈、透镜状沿层间断层破碎带分布,中寒武统田蓬组(∈2t)碎屑岩及大理岩化、矽卡岩化为之近矿围岩。老君山花岗岩浆的侵入活动为该铜矿、锡矿的形成提供了成矿热液。Manjiazhai Cu deposit, Maguan is in the outer contact of Laojunshan granite body in SE Yunnan. The most discovered ore bodies are lenticular, distributed along the interlayer fracture zone. The wall rock near ore body is Middle Cambrian Tianpeng Formation （ ∈2t ） clastic rock, marbleization, skamization. Laojunshan granite intrusion provides the metallogenetic thermal fluid for the formation of Cu-Sn deposit.
