摘要
郭仓乐玛锌铜矿位于青海省西南部,三江多金属成矿带北西段。矿区圈出7个锌矿体、1个铜矿体,矿体严格受北西向断裂控制,含矿岩性为碳酸盐化硅化碎裂岩,围岩为二叠纪开心岭群诺日巴尕日保组灰岩。结合郭仓乐玛地区区域地质构造背景,阐述了矿区地质特征、物化探异常特征及矿化体特征等,进而确定了矿床控矿因素和找矿标志,探讨了矿床成因,证实郭仓乐玛矿区具有较好的找矿潜力。
Guocanglema zinc-copper deposit is located in the southwest of Qinghai Province,in the north-west section of the Sanjiang polymetallic metallogenic belt.Seven zinc orebodies and one copper orebody have been identified in the mining area.The orebody is strictly controlled by NW trending faults.The ore-bearing lithology is carbonate silicified cataclasite.The Ore-bearing rock is the limestone of the Permian Kaixinling Group,Nuoribagaribao formation.Based on the regional geological tectonic setting of Guocanglema area,the geological features,geophysical and geochemical anomalies and mineralized body features of the mining area are all described.The ore-controlling factors and prospecting criteria are determined.The Genesis of the deposit is discussed about.It is proved that Guocanglema mining area has better prospecting potential.
