| 摘 要： | 通过地貌、地质构造、地球物理、区域成矿等方面的综合分析，论证了黑龙江右岸北西向小兴安岭大型-特大型有色、贵金属成矿带的存在.矿带主体部分为北西向小兴安岭山脉，长达1000 km，宽约500 km，矿带内的控容矿地质构造呈北西向展布，矿床（体）呈北西向带状分布.深部地球物理异常构造趋势揭示，成矿带是一大规模的北西向岩石圈-软流圈构造异常区.区域地质资料分析表明，该矿带历经了陆块形成、古亚洲构造域活动大陆边缘造山、滨太平洋活动陆缘造山三大构造-成矿演化阶段.该矿带的确认对于进一步认识中国东部构造-岩浆-成矿规律具有重要意义.

| Abstract: | A comprehensive analysis on the geographic,tectonic,geophysical and regional metallogenic data reveals the existence of the NW-trending Xiaoxinganling tectonic-metallogenic belt of nonferrous and precious metals on the right bank of Heilongjiang River.The main part of the metallogenic belt,1000 km long and 500 km wide,is along the NW-trending Xiaoxinganling mountain chains,in which the ore-controlling and hosting structures are distributed in northwest direction,with ore deposits occurring in a belt trending northwest.Geophysical data show that the metallogenic belt is consistent with a large lithospheric-asthenospheric structural anomaly zone.The regional geological data support the formation of the metallogenic belt through three tectonic-metallogenic evolution stages,which are the forming of landmass and active continental margin orogeny in the Pal-Asia tectonic domain,followed by active continental margin orogeny in the marginal-Pacific tectonic domain.The confirmation of the existence of this metallogenic belt is of great significance to better understand the tectonism-magmatism-metallogeny in East China. |
