摘要
克停哈尔铜锌矿床是近年来在东昆仑造山带西段新发现的一处矿床,并且在隐爆角砾岩中发现了锌矿体,为查明隐爆角砾岩成因及与成矿的关系,对隐爆角砾岩进行了主量、微量及稀土元素的分析和研究。研究结果显示,w(SiO_2)为64.13%~66.54%,w(Al_2O_3)为14.55%~15.59%,w(Na_2O+K_2O)为6.29%~7.24%,K_2O/Na_2O比值为0.87~1.17,A/CNK比值为0.971~1.121,属于过铝质高钾钙碱性岩石系列;稀土元素总量中等,轻稀土元素富集,中等负铕异常;富集大离子亲石元素(Rb、K)、活泼不相容元素(Th)和轻稀土元素,相对亏损高场强元素(Ta、Nb、Ti、P、HREE),总体反映具壳源为主的花岗岩特征,形成于碰撞造山晚期并开始向陆内造山伸展环境转变,至少存在2期爆破3期成矿,第二期爆破是铅锌矿的主要成矿期。
        The Ketinghaer copper-zinc deposit is a polymetallic deposit recently discovered in the western part of the East Kunlun Mountains, and the zinc orebody was found in the cryptoexplosive breccia. In order to find out the genesis of the cryptoexplosive breccia and its relation to metallogenesis, the authors studied major elements, trace elements and rare earth elements of the cryptoexplosive breccia. The results show that the values of major elements of the cryptoexplosive breccia are w(SiO_2) from 64.13% to 66.54%, w(Al_2O_3) from 14.55% to 15.59%, w(Na_2 O+K_2 O)from 6.29% to 7.24%, Na_2 O/K_2 O ratios from 0.87 to 1.17, and A/CNK ratios from 0.971 to 1.121, suggesting peraluminous high potash calc-alkaline series. ΣREE values of the cryptoexplosive breccia are medium, exhibiting enriched LREE and moderate negative Eu anomaly; the breccia is strongly enriched in LILE(K, Rb), and mobile incompatible elements(Th) as well as LREE and depleted in HFSE(Ta, Nb, Ti, P, and HREE), implying that magma was dominated by crustal rocks and was formed in the late collision orogeny which began to be converted into a post collisional extension environment. There existed at least two phases of blasting and three phases of minera lization in the cryptoexplosive breccia, with the second phase being the main mineralization phase of Pb-Zn ore.
