摘　　要：黑龙江伊春-延寿地槽褶皱系构造复杂,岩浆活动具多期性,成矿作用与岩浆岩关系密切,形成了与加里东期、印支期、燕山期侵入岩(火山岩)有关的金及多金属矿床,矿床类型属交代热液型矿床.研究区处于闭合边缘的岛弧或活动陆缘构造环境,与成矿有关的岩浆岩具高酸高钾特征.古元古界东风山群、古生界西林群、二叠系土门岭组、白垩系板子房组、甘河组、光华组火山岩为成矿提供了矿源.In the Yichun-Yanshou geocynclinal zone with complicate tectonics and structures,the metallogenesis is closely related to the magmatic intrusions,which acted in multiple episodes.The gold and polymetallic deposits of hydrothermal and metasomatic type are related to Caledonian,Indosinian and Yanshanian intrusions（or volcanic rocks）.The studied area belongs to island-arc or active continental margin environment,in which the magmatic rocks are characterized by high-Si and high-K.The volcanic rocks from Proterozoic Dongfengshan group,Paleozoic Xilin group,Permian Tumenling formation,Cretaceous Banzifang,Ganhe and Guanghua formations are the source of ore material.
