摘要
小红山铜矿位于西伯利亚板块南缘阿尔泰陆缘活动带中,区内构造演化复杂,岩浆活动强烈,具有较好的成矿条件。通过对小红山铜矿地表、深部原生晕空间套合与叠加分析,以及稀土、微量、同位素等岩石地球化学测试,研究了矿体空间分布规律、矿床成因和成矿机理,认为小红山铜矿属于中低温岩浆热液铜矿床,受构造及变霏细岩的控制。对铜矿区进行了成矿预测,划分出找矿靶区5处,其中A类和B类找矿靶区各1处,C类找矿靶区3处。
Xiaohongshan Cu deposit is located at Aletai continental marginal belt of the south margin of Siberia plate.The deposit area is complicated in tectonic evolution history and strong in magmatism with favorable metallogenic condition.Spatial distribution,genesis and metallogenic mechanism based on overprinting the primary halo at surface and depth,geochemical analysis of REE,trace element and isotopes of the Cu deposit show that the deposit is a magmatic meso-epithermal deposit controlled by structure and meta-felsite.5 targets are predicted of which 1 is classⅠ ,1 class Ⅱ and 3 class Ⅲ.
