白龙江中上游地区微细浸染型金矿，是受地层和构造双重控制的金矿床。在阐述矿床空间分布规律、控矿因素、区域矿化和地球化学特征等基础上，初步建立了地质地球化学成矿模式。 Finely disseminated gold deposits in the middle and upper reaches of Bailongjiang are gold deposits controlled by both strata and structure. Based on the description of the spatial distribution of ore deposits, ore-controlling factors, regional mineralization and geochemical characteristics, the geo-geochemical metallogenic model has been initially established.
