新疆阿尔泰诺尔特地区经历了前泥盆纪基底陆壳演化期、上叠盆地发育期、上叠盆地的关闭期和造山后期4个阶段; 在地质演化过程中伴随着一系列成矿作用.区域化探资料显示,区内下石炭统中-酸性火山岩出露区以Au、Pb、Zn、Cu为特色的化探综合异常带规模大,强度高,化探异常浓集中心明显,在部分异常区内已经先后发现多处金、铜、多金属矿床、矿点和矿化点.区域构造演化富集了成矿元素,特别是下石炭统红山嘴组火山岩为金、铜、铅、锌矿源层,燕山期岩浆活动对矿源层中的成矿元素进一步富集,并在构造有利部位成矿.本文通过研究区区域成矿条件和区域化探异常特征分析,指出诺尔特地区具有较大的找矿潜力.

The Nurt area has four evolution stages, i.e., the Pre-Devonian continental basement formation stage, the basin evolution stage, the basin closed stage and post-orogenic evolutional stage; with the long time geological evolution, extensive mineralization developed. The regional exploration geochemical data indicate that the Au, Pb, Zn, Cu exploration abnormities are in large-scale, high intensity and obvious abnormity concentration centers. These Au, Pb, Zn, Cu exploration abnormities distributed along the Lower Carboniferous volcanic rocks distribution region, and the Lower Carboniferous Hongshanzui Formation volcanic rocks are important ore-bearing strata. A number of copper, gold and polymetallic deposits, mining, and mineralization points have been found in the exploration abnormities. Ore-forming elements were further enriched and formed gold ore bodies in beneficial structural parts during Yanshanian magmatic activities. The regional exploration geochemical abnormities and mineralization conditions show that the exploration potential is large in Nurt region.
