通过对尕龙格玛铜多金属矿区侵入体(花岗闪长岩和石英闪长岩)岩石学特征、岩体侵位年代、地球化学特征、岩浆演化过程进行分析研究，认为本区花岗闪长岩和石英闪长岩可能形成于后碰撞构造背景，岩体侵位时限定位印支期晚三叠世较为适宜，格仁涌花岗闪长岩属分异的 I 型花岗岩。本区侵入岩体可能为矿体的形成提供了持续的热动力条件，为成矿带来了部分成矿物质，岩浆侵入对本区铜多金属矿形成有明显控制作用。

Through analyzing petrologic characteristics,age of rock emplacement,geochemical characteris-tics,magma evolution process of the intrusive bodies (granodiorite and quartz diorite)in Galonggema Cu polymetallic mine area,this paper argues that the granodiorite and quartz diorite may be formed in post-colli-sion settings,and it should be appropriate to determine that the emplacement age is in late Triassic of Indo-chinese epoch,and granodiorite in Gerenyong should be differential type I granite.The intrusive rocks in the area may have provided thermo-motive for the formation of rock bodies,and have brought part of the metal-logenic materials for mineralization.The magmatic intrusion obviously controls the formation of Cu poly-metallic ores.
