中国长白—朝鲜惠山地区成矿带划分、延伸及对比分析

Division,extension and contrast analysis of the metallogenic belt in Changbai-Huishan area,China and Korean

吉林省临江一长白地区与朝鲜惠山—利原成矿带、狼林古陆相接壤。但临江一长白地区目前所发现的矿产与朝鲜相比,尚有较大的差距。本文从区域角度多方位对鸭绿江两侧成矿地质条件进行对比分析,重点对长白—惠山一带的鸭绿江沿岸地区成矿带进行了具体的划分、延伸和对比;并对长白地区今后的找矿方向进行了讨论。

Jilin Linjiang-Changbai area is border on North Korea Huishan-Liyuan metallogenic belt, Langlin old land. But there are still large gap between the mineral discovered in the Linjiang-Changbai area and that in North Korea. In this paper, from the angle of region, the ore-forming geological conditions on the both sides of the Yalu River are compared and analyzed, focus on metallogenic belt of Changbai-Huishan area of the Yalu River coastwise area were divided, extended and contrasted, and the future prospecting direction in the Changbai area are discussed.
