| 摘 要： | 四川九龙笋叶林铜矿床位于江浪岩浆-变质核杂岩北部，是里伍铜矿外围一个矿区。本文从地层、构造、岩浆岩、围岩蚀变、矿体特征、矿石特征等方面进行矿床地质特征分析。并通过钻孔深部验证，着重对S-3和S-4矿体的深部延伸情况进行了研究。研究发现笋叶林矿区围岩蚀变十分强烈；矿体呈似层状产出，品位、厚度等在深部变化较大，深部发现多层矿化体，矿石品位普遍不高；硅化石英脉、绢白云母化、石榴石化与矿化关系密切。最后，认为在外围的笋叶林矿区寻找铜矿有较好的前景。 |

| Abstract: | The Sunyelin copper deposit which is situated periphery of Liwu copper ore field is near the north of Jianglang magma - metamorphic core complex. Here the stratum, structure, magma intrusion, wall - rock alteration, ore - body feature and ore characters of Sunyelin deposit are reported to introduce the met- allogenic environment. The extension status of S -3 and S -4 ore -body to the deep is investigated by deep drilling, which shows intensive alteration in the whole ore- body, and the grade and thickness of the strati- form - like ore - body changed greatly, and grade of the most ore - body is poor. The mineralization is closely related to some wall -rock alteration, such as silicification, sericitization and garnatization etc. It＇s indicated that the Sunyelin copper deposit has got great prospecting potential in the Liwu copper ore field. |
