摘要
嫩江-黑河地区多宝山岛弧多宝山矿集区新发现了晚三叠世二道坎大型银矿床,铜山矿床深部取得重大找矿突破;科洛-新开岭构造杂岩带新发现晚三叠世孟德河金矿床,三合屯金矿区外围深部也发现了金矿化;塔溪岩浆弧新发现了早白垩世宝泉小型铜矿床.这些矿床与区域圈定的化探异常较吻合,成矿规律较明显.依据新发现的铜金矿成果,总结了嫩江-黑河地区近年来取得的新近展,指出了下一步找矿方向和今后勘查工作部署建议,为即将实施的战略找矿行动勘查部署提供参考依据.
The large Late Triassic Erdaokan silver deposit is discovered in Duobaoshan ore concentration area of Duobaoshan island arc in Nenjiang-Heihe area,and the exploration in the deep part of Tongshan deposit also makes a great breakthrough.The Late Triassic Mengdehe gold deposit is found in Keluo-Xinkailing tectonic melange belt,and the gold mineralization in the deep of Sanhetun goldfield periphery as well.The small Early Cretaceous Baoquan copper deposit is discovered in Taxi magmatic arc.These deposits are consistent with regionally delineated geochemical anomalies with obvious ore-forming regularity.Based on the new discoveries of copper and gold deposits,the paper summarizes the latest prospecting progress in Nenjiang-Heihe area in recent years,pointing out the next exploration direction and suggestions for future prospecting and providing reference for the upcoming strategic prospecting deployment.
