哀牢山-金沙江新生代铜矿带是藏东最重要的铜矿带之一。位于该带北部的囊谦盆地,坐落于玉龙斑岩铜矿带东部100 km处。最近该盆地内发现有长英质侵入岩体。玉龙铜矿是中国最大的斑岩型铜矿之一,赋存于后碰撞构造环境下形成的过铝质、埃达克质的碱性岩浆中(Hou et al.,2003;Jiang et al.,2006;Liang et al.,2007)。囊谦盆地内的富碱侵入岩包括二长斑岩和正长斑岩,尽管近些年来进行了 Ailaoshan - Jinsha River Cenozoic copper belt is one of the most important copper belt in eastern Tibet. Located in the north of the cypress Qian basin, located in the Yulong porphyry copper belt 100 km east. In the recent basin, there have been the discovery of quartzite intrusions. The Yulong copper deposit is one of the largest porphyry copper deposits in China and occurs in peridotite and adakitic alkaline magmas formed in the post-collision tectonic setting (Hou et al., 2003; Jiang et al. , 2006; Liang et al., 2007). Alkali-alkali intrusions in the basin-scale basin include the monzonitic porphyry and the plagioclase porphyry, although in recent years
