四川九龙中咀铜矿床为近年来新发现的一个产于江浪变质核杂岩中的富铜矿床。矿体呈似层状,受韧性剪切带控制,矿体在走向和倾向上延伸稳定。主要矿石类型为浸染状、网脉状、角砾状、块状铜锌矿石。矿石建造为FeCu-Zn建造。金属矿物由黄铜矿、磁黄铁矿、闪锌矿、方铅矿等组成。主要蚀变类型为石榴子石化、绢云母化、绿泥石化、黑云母化。矿体铜品位较高,平均品位为1.65%。目前该矿床仍在进行详查地质工作,矿区向东和向北西方向仍具有较好的找矿前景。该矿床的发现与评价,对于重新认识里伍铜矿床外围找矿潜力和进一步指导该区找矿工作具有重要意义。
The Jiulong Zhongzui copper deposit in Sichuan Province is a newly discovered copper-rich copper deposit in Jianglang metamorphic core complex recently discovered. The orebodies are stratified and controlled by ductile shear zones, and the orebodies extend and stabilize in the direction and tendency. The main ore types are disseminated, reticulate, brecciated, massive copper-zinc ore. Ore construction was built for FeCu-Zn. Metal minerals from chalcopyrite, pyrrhotite, sphalerite, galena and other components. The main alteration types are pomegranate, sericitization, chloritization and biotite. Copper ore grade higher, with an average grade of 1.65%. At present, the deposit is still undergoing detailed geological work, and the mining area still has a good prospecting prospect to the east and to the northwest. The discovery and evaluation of the deposit are of great significance for the re-understanding of the potential for prospecting in the periphery of the Liwu copper deposit and for further guiding the prospecting work in the area.
