| 摘 要： | 英城子金矿床是小兴安岭-张广才岭成矿带极具代表性的矿床.金矿体呈脉状、透镜状产出于叠加在韧性剪切带之上的脆性断裂带内.矿床地球化学分析表明,容矿的二长花岗岩、流纹岩具有钙碱性系列岩石特征,形成于火山弧和同碰撞构造环境,由原始地幔岩浆演化形成.成矿流体具有中低温中低盐度幔源流体特征,金矿成矿与后韧性剪切变形时期的构造-岩...

| Abstract: | Yingchengzi gold deposit is a representative deposit in Xiaoxing'anling-Zhangguangcailing metallogenic belt.With vein or lentiform shape,the gold orebodies locate in brittle fracture belts,superpositioning over ductile shear belts.The geochemical analysis on the deposit reveals that the ore-bearing adamellite and rhyolite possessed the characteristics of calc-alkali series rock,they formed in volcanic arc and collision structural environment,and evoluted from original mantle magma.The ore-forming fluid had ... |
