摘　　要：云南省德钦县茂顶铜矿区有两种类型的铜矿体,一种以MKT1铜矿体为代表,呈透镜状赋存于二叠系上统(P2b)灰岩与花岗闪长岩体接触的矽卡岩带中,为矽卡岩型铜矿床,其空间分布上受岩体接触带矽卡岩控制;另一种以MKT2铜矿体为代表,赋存于上元古界(Pt3?)内断层构造(F6、F7)破碎带中,该类矿体受构造破碎带控制明显,为产于破碎带中的热液型脉状铜矿.There are 2 types of Cu orebodies in Maoding Cu orefield of Deqin,Yunnan,one of them is representative by the Cu orebody MKT1,lenticular in the skarn zone of contact between Upper P limestone(P2)and granodiorite body,the skarn-type Cu deposit,controlled by the skarn of contact zone in the space distribution;another is representative by the Cu orebody MKT2,in the fault fracture zone(F6,F7)of Upper Proterozoic(Pt3?),controlled clear by structural fracture zone,belonging to the veined hydrothermal Cu deposit in fracture zone.

关 键 词：矽卡岩型矿床、热液型矿床 云南德钦茂顶
