黑龙江嘎拉山、福草山地区金矿控矿因素及找矿标志

Discussion on Ore-controlling Factors and Prospecting Indicator of Gold Deposit in Galashan and Fucaoshan Region,Heilongjiang Province

研究区位于东乌珠穆沁旗—嫩江Ⅲ级成矿带之多宝山—黑河Ⅳ级铜、钼、金、铁、锌成矿亚带上,成矿地质条件优越。近年来,通过开展省补"矿调"项目,相继在该区发现了一批具有较大找矿潜力的矿点和矿产地,显示了研究区具有较好的找矿远景。本文通过分析研究区地层、构造、岩浆岩及航磁异常与金成矿关系,对研究区主要的控矿因素有了进一步的认识,并初步建立和总结了本区的成矿模式及找矿标志,为该区下一步金矿找矿指明了方向。

The research area lies on Duobaoshan-Heihe Cu-Mo-Au-Fe-Zn metallogenetic belt,which is the subbelt of Dongwuzhumu-Nenjiang metallogenetic belt.Lots of ore deposits and prospective areas are discovered by the investigating programs of minerals and resources of Heilongjiang Province,which indicates that the research area is excellent in ore-prospecting potential.The thesis focuses on the relationship among strata, tectonic,magmatic rocks,aerial magnetic anomaly and gold-metallogeny,and the major ore-controlling factors are discussed.The metallogenic model and prospecting sign are Preliminary established and summarized.The research is helpful to the further ore-hunting in the area.
