摘要
哈萨克斯坦巴尔喀什成矿带科翁腊德斑岩型铜矿床从发现至今已经走过了70年的历程,它是发育在陆缘弧环境的典型超大型斑岩型矿床,具有花岗闪长岩型斑岩铜矿成因模式。矿床围岩蚀变与矿石矿物组合的垂直和水平分带明显,氧化带和次生硫化物富集带矿石品位高,易开采。矿床整体属于浅部成矿,受环状构造控制,次生石英岩和泥化等蚀变与矿床的关系最为密切。目前该矿床已开发殆尽,前景堪忧。
The Kounrad porphyry copper deposit was discovered 70 years ago in the Balkhash Metallogenic Belt of the Central Asian Metallogenic Domain,.It is a typical super-large porphyry copper deposit developed under the tectonic environment of continental margin arc,with a metallogenic model of granodiorite.The vertical and lateral zonings of the wall rock alteration and ore mineral assemblages are obviously observed in the deposit.High content ore in the leaching zone and the ore deposition at a very shallow depth made it easy to be mined.It is suggested that the metallogenesis of the deposit was controlled by the circular structure,and had a very close relation with the secondary quartzite and argillic alteration.
