西呼和楚鲁地区位于大兴安岭北段,由于森林沼泽覆盖和自然保护等原因,地质调查工作程度低,尚未取得找矿突破。近期开展的地球化学调查成果显示,与陆壳克拉克值相比,区域Ag、Pb、W、As、Sb、Bi元素富集,尤其是在石炭系莫尔根河组和早石炭世闪长岩、晚泥盆世石英闪长岩中含量很高,Cu、Au、Sn相对贫化;大多数成矿元素在区域内分布不均匀,尤其是Au、Ag、Mo、Bi在侏罗系满克头鄂博组、石炭世二长花岗岩和闪长岩体出露区分异极强,Cu在泥盆系大民山组、早白垩世花岗岩中,Au在石炭系莫尔根河组、晚泥盆世石英闪长岩中呈强分异型分布,在局部区域存在富集甚至强烈富集,较为利于成矿。区域主要成矿元素为Au、Pb、Ag、Mo、Cu,伴生成矿元素为W、As、Sb、Sn、Mn、Bi、Zn,主要成矿类型为热液型、火山岩型。根据区域地球化学特征,预测区域成矿潜力较大的地区为锡尼河-那日斯毛德、大架子山、一支沟-小孤山等地。
Western call and Chulu area is located in the northern part of Daxingan Mountains. Due to the coverage of forest swamps and nature conservation, the geological survey has a low degree of workmanship and has not yet made any prospecting breakthrough. Recent geochemical survey results show that the elements Ag, Pb, W, As, Sb and Bi are enriched in the area compared with the continental crust values, especially in the Carboniferous Morgen and Early Carboniferous diorites , The late Devonian quartz diorite is high in content, Cu, Au and Sn are relatively depleted; most of the ore-forming elements are unevenly distributed in the region, especially Au, Ag, Mo and Bi in the Jurassic Upper Obo Formation, Carboniferous monzogranite and diorite body are very different from each other. Cu is widely distributed in the Devonian Damingshan Formation and Early Cretaceous granite. Au is mainly distributed in the Carboniferous Morgan Group, In the quartzite diorite, there is a strong heterogenous distribution, which is enriched or even strongly enriched in the local area, which is more conducive to metallogenesis. The main ore-forming elements in the area are Au, Pb, Ag, Mo and Cu, and the associated ore-forming elements are W, As, Sb, Sn, Mn, Bi and Zn. The main metallogenic types are hydrothermal and volcanic types. According to regional geochemical characteristics, the regions with large potential for metallogenetic prediction in the area are the Sinai River - Nazi Maude, Dajiasizi, Yizigou - Xiaogushan and other places.
