摘要
黑龙江省多宝山-宽河成矿带铜金矿产十分丰富.区内于早奥陶世初形成的“四隆四拗”构造格局控制了以后各地质时期地层、岩浆演化及矿产的分布.通过对矿带成矿地质背景、物化探异常、典型矿床特征的分析与归纳,总结了铜金成矿规律、成矿条件与找矿标志,预测出9个找矿重点靶区.
The Duobaoshan-Kuanhe metallogenic belt is abundant in copper and gold resources. In early Ordovician, the structural framework was formed with four uplifts and four depressions, which were developed as NE-trending deep fault belts and NW-trending splitting belts and controlled the stratigraphy, magmatism and distribution of minerals in the area. By study on the metallogenic conditions and regularities of the copper and gold deposits, with analysis on the geological background, geophysical and geochemical anomalies and characteristics of the typical deposits within the belt, nine significant targets are located.
