黑龙江省奥陶纪浊积岩及金矿床找矿远景

以多宝山—罕达气地区为例阐述了黑龙江省奥陶纪浊积岩及特征,并与国外典型浊积岩金矿床对比。指出该区曾处于西伯利亚板块和中朝板块之间的早古生代褶皱带,呼玛县兴隆地区和黑河市罕达气地区处于西伯利亚板块南缘的弧间盆地或弧后盆地,奥陶纪浊积岩十分发育,具有浊积岩型金矿床容矿岩石的典型特征;本文以省内浊积岩分布区金矿为实例,说明该地区将成为奥陶纪浊积岩金矿床的找矿远景区。

Ordovician turbidite and its potential in gold exploration in Heilongjiang Province

Occurrence and features of turbidite in the Heilongjiang Province are discussed by examining those in the Duobaoshan-Handaqi area,and compared to the host rocks of typical trubidite-type gold deposits in abroad.It is suggested that the region was an Early Paleozoic foldbelt between the Siberian and Sino-Korean plates,and the areas Xinglong of Huma and Handaqi of Heihe were either intra-or back-arc basins,in which Ordovician turbidite was well developed and shows typical characterizations of the turbidite-type gold deposits as host rock.The listed examples of gold deposits in the province indicate that the Ordovician turbidite is great potential in this area for further gold exploration.
