摘要
文章在系统分析和总结成矿地质背景、矿区地质特征、矿体形态及分布规律和矿石组构类型的基础上,分析了控矿因素和矿床成因,指出了找矿靶区。艾娜克铜矿赋存于背斜构造的两翼和封闭转折端,严格受上元古代洛伊赫瓦尔组地层控制,时空特征明显。同生成岩成矿期后的变质作用使成矿元素迁移富集,同时使岩矿定向排列,形成片理线性构造,认为艾娜克铜矿属于同生沉积变质矿床。
according to geological background and geological characteristics and ore body and ore construction type. These factor is anylisted and surmmied by arthor. Analysis of genesis of ore-controlling factor and that the prospecting targets. Aynak copper mine occur in anticline flanks and closed transition side, strictly by the Lantern of Ancient Louie hertz var Formation control, spatial and temporal charac- teristics significantly. Anticline axis as the Lantern of Ancient Vera Yawkey group amphibole schist and paragneiss, with two limbs of ancient Louie hertz varfor the Lantern Group dolomite, carbonate, biotite schist,carbonaceous quartz schist and carbonaceous schist. The mineralization is not associated with post-magmatie mineralization and linear structure ,The metamorphic rocks forming the role of post-migration lead to ore-forming elements enrichment. While making rock linage by orientation, the formation of schistosity linear structure. Then Aynak copper mine is belong to co-sedimentary deposits.
