摘要
Huancabamba铜多金属矿区位于秘鲁南部阿普里马克省,其划属Apurimac始新世—渐新世斑岩—矽卡岩型铜矿带。矿区以出露中新生带砂岩、碳酸盐岩为特征,渐新世花岗闪长岩、石英闪长岩侵入,造成地层矽卡岩化、矿化。矿区A1、A2、A3分别表现为铜银矿化、铜矿化、金矿化,地表矿体受到硅化破碎带的控制,规模较大。根据地表矿化特征及其区域地质背景,综合分析认为Huancabamba铜多金属矿区深部具有寻找斑岩-矽卡岩型铜多金属矿的前景。
Huancabamba Cu polymetallic mine is located in Apurimac province,south of Peru.It belongs to Apurimac Eocene epoch-oligocene porphyry-skarn type copper ore belt.The mine is characterized by meso-cenozoic sandstone outcropping and carbonate rocks,intruded by Oligocene granodiorite and quartz diorite,resulting in skarn alternation and mineralization.A1Area,A2 Area and A3 Area of mine show signs of Cu-Ag mineralization,Cu mineralization and gold mineralization respectively.Ground orebody is controlled by silicified fracture belt on a large scale.According to ground orebody mineralization characteristics and regional geological background,it’s believed after comprehensive analysis that deep section of Huancabamba Cu polymetallic mine has a prospect for finding porphyry-skarn type Cu polymetallic ores.
