| 摘 要： | 本文从构造环境与成矿作用关系的角度，论述了研究区不同构造单元的成矿特征。宗乃山－沙拉扎山岛弧区有利于寻找热液型、矽卡岩型的铁、铜矿床和多金属矿床；查干础鲁－霍尔森边缘海蛇绿混杂带是寻找铬铁矿的有利地带；雅布赖－巴音诺尔公大陆弧区的成矿作用比较复杂，随着构造的演化有铜、镍－铜、铁－钨、锡和萤石等矿化的演变过程。与边缘海洋壳俯冲有关的那仁哈拉韧性剪切带很可能形成原生金矿。

| Abstract: | In view of the relationship between tectonic setting and mineralization,thispaper discusses mineralizational features of various tectonic units in this area.Zongnaishan-Salazashan island are zone is favourable to finding hydrothermal-skarn typeiron,copper and polymetal deposits;Huoerseng-Chaganchulu marginal sea ophioliticzone is favourable to finding the ores of ferrochromite;with its tectonic evolution,Yab-ulai-Bayinnuoergong continental arc has copper,nickel-copper,iron-wolfram,tin andfluorite mineralization.Narenhala ductile shear belt,as it was related to the subductionof marginal sea,may probably have formed original gold deposits. |
