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。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很密切。最后,认为在外围的笋叶林矿区寻找铜矿有较好的前景。

Abstract: Sunyelin copper deposit in Sichuan Jiulong is located in the north of Jianglang magma - metamorphism core complex, and is one of mining areas in Liwu copper mine. The Geological Characteristics of Sunyelin copper deposit was analyzed from the stratum, structure, wall-rock alteration, ore-body characteristics and ore nature. By deep proof with drilling, the extension variation in depth on S-3 and S-4 ore-body was studied. It was showed that wall-rock had a strong alteration. And its grade and thickness of the stratoid ore-body vary in depth. There are multi-storied ore-body with low grades. Metallization is connected with silicified quartz reef, sericitization and garnet, and so on. Thus there is a good prospection for hunting copper deposits surrounding the Sunyelin copper deposit.
