摘要
漠河地区火山岩分布较广泛， 共有３ 期火山活动。以中基性岩为主， 夹有中酸性岩。目前已发现４ 处与中酸性火山活动有关的岩金矿（化） 点， 产出受 Ｎ Ｎ Ｅ、 Ｎ Ｅ向及环形断裂控制， 成矿时代为燕山晚期， 属中—低温火山热液型。
The distribution of volcanic rocks in Mohe are extensive. There are three periods of volcanic activities in this region. The rocks are mainly neutral basic rocks, mixed with neutral acid rocks. At present, four rock gold mineralization points related with neutral acid volcanic activities have been found. The produces are controlled by ring faults trending NNE and NE. The metallogenic epoch is late Yanshan period. The gold mineralized points belong to meso epithermal volcanogene hydrothermal type.
