1区域成矿背景多宝山铜矿床位于黑龙江省黑河市嫩江县,构造位置上属于中亚造山带东段大兴安岭北部的早古生代陆缘增生构造带-多宝山奥陶纪岛弧型活动带,该矿床位于兴蒙造山带最东端,大兴安岭褶皱带与吉黑褶皱带的接合部位(韩振新,2004)。矿区内出露地层主要是奥陶系和志留系火山-陆源碎屑岩及砂泥质岩,其中中奥陶统多宝山组为矿体的顶部围岩。与成矿关系密切的侵入
1 Regional Metallogenic Background The Duobaoshan copper deposit is located in Nenjiang County, Heihe City, Heilongjiang Province. It is characterized by the Early Paleozoic continental margin tectonic belt - Duobaoshan Ordovician arc belt in the northern Da Hinggan Mountains in the eastern part of the Central Asian orogenic belt. The deposit is located at the junction of the Daxinganling fold belt and the Jihe fold belt at the eastern end of the Xingmeng orogenic belt (Han Zhenxin, 2004). The exposed strata in the mining area are mainly Ordovician and Silurian volcano-terrigenous clastic rocks and sandy shaly rocks, of which the Middle Ordovician Duobaoshan Formation is the top of the ore body.
