| 摘 要： | 吉黑东部是我国东北地区极具潜力的重要成矿区带.区内燕山期为最重要的成矿期,具有很高的工业价值.具找矿前景的主要矿床类型是与燕山早期岩浆侵入活动有关的细脉浸染型钼矿、接触交代型铁、多金属矿床和与燕山晚期火山喷发-超浅成侵入体有关的浅成低温热液型金(银)矿床、斑岩-浅成低温热液型金(铜)矿床.有利的找矿地段为1伊春-滨东-吉中地区燕山早期二长花岗岩、花岗闪长岩、花岗闪长斑岩分布区;2呼玛-黑河-逊克-嘉荫以南燕山晚期陆相火山岩分布区;3东宁-汪清-珲春地区燕山晚期陆相火山岩-超浅成侵入岩分布区.

| Abstract: | The eastern part of Jinlin and Heilongjiang provinces is a very important metallogenic belt with great potential in Northeast China. Yanshanian is the most significant metallogenic period of the area. The prospective ore deposits involve two major types. One is veinlet-disseminated Mo deposits and contact metasomatic Fe-polymetallic deposits, which are related to the Early Yanshanian magmatic intrusive activities. The other is epithermal Au (Ag) deposits and porphyryepithermal Au (Cu) deposits, which are connected with Late Yanshanian volcanic eruption-ultra hypabyssal intrusion. The favorable prospecting areas are: 1) the distribution of Early Yanshanian adamellite, granodiorite and granodiorite porphyry in Yichun-Bindong-Jidong; 2) the Late Yanshanian terrestrial volcanic rock distribution in the south of Huma-HeiheXunke-Jiayin; and 3) the Late Yanshanian terrestrial volcanic rock and ultra hypabyssal intrusion distribution in DongningWangqing-Hunchun. |
