| 摘 要： | 内蒙古大井大型锡多金属矿床是一个与次火山热液有关的脉状矿床,其成矿元素组合复杂,具有亲氧(锡)和亲硫(铜铅锌银)两套成矿元素组合.矿区范围内脉岩发育,与成矿关系密切,可分为霏细岩和英安斑岩两大类.霏细岩以斑晶不发育、硅化绢云母化强烈及Eu亏损明显等为特征,与早期阶段的锡成矿有关;英安斑岩以斑晶发育、黄铁矿化强烈及Eu异...

| Abstract: | The Dajing tin-polymetallic deposit, Inner Mongolia, is a hydrothermal vein-type deposit related to volcanic and sub-volcanic rocks. The ore-forming elements are complicated, which have oxyphile (Tin) and chalcophile (Cu, Pb, Zn, Ag) ore-forming elements combination. Dykes in this mining area well development. They can be divided into two categories: felsitic rock and dacite porphyry rock. In the felsitic rock, phenocrysts are not developed, silicified and sericitization strongly, and the features of loss o... |
