摘要
北大岩金矿位于三道湾子岩金矿的外围,是近年来黑龙江省地勘局发现的品位较高的岩金矿之一。本文论述了该矿床地质背景、矿体特征、成矿期次、流体包裹体特征,对矿床成因进行了探讨,对矿床形成条件进行了总结,提出了北大沟金矿为与火山热液有关的中-低温浅成热液矿床。
The Beidagou gold deposit is located in the periphery of Sandaowanzi gold deposit which is one of the higher grade gold deposits discovered by Bureau of Geologic Exploration and Mineral Development of Heilongjiang Province in recent years.The authors described geologic setting of ore deposits,characteristics of orebodies,ore-forming stages and times,and fluid enclosure characteristics,discussed genesis of the ore deposit,summarized the formation conditions,and proposed that Beidagou deposit belongs to mid-epithermal ore deposit related to volcanogenic hydrothermal solution.
