摘　　要：俄罗斯远东地区是世界极其重要的内生金属聚集区,其金、银、铜、钨、锡等矿产资源量极其丰富。主要介绍研究区域涉及的地质构造单元,包括北亚克拉通东北部边缘之上扬斯克被动陆缘、上扬斯克—楚科奇造山带、鄂霍茨克—楚科奇造山(火山岩)带、科里亚克—勘察加造山带,简述俄罗斯远东地区东部地质构造演化,对鄂霍茨克—楚科奇成矿带及其毗邻地区的主要内生金属成矿作用进行了总结。在火山岩带,火山坳陷盆地的优势矿产是浅成低温热液型金银矿床,而在火山岩带相对隆起区的花岗质岩石分布区则发育斑岩型铜矿床和铜钼矿床。Russian Far East area is an important endogenic metal cluster area in the world, where gold, silver, copper, tungsten, tin and some other mineral resources are extremely rich. The study area includes Verkhoyansk craton marginal zone in northeast North Asia craton,Verkhoyansk-Chukchi orogenic belt, Okhotsk-Chukchi orogenic （volcanic rock） belt, and Koryak-Sakhalin orogenic belt. In this paper, the authors briefly described regional tectonic evolution and geological setting for ore-forming processes of northeast Russian Far East, and summarized the ore-forming processes of main endogenic metal deposits in Okhotsk-Chukchi volcanic belt and its neighboring areas. It is considered that, in this volcanic belt, the epithermal gold-silver deposits are dominant mineral deposits in the volcanic basin, whereas the porphyry copper deposits and copper-molybdenum deposits are mainly distributed in the granitoid rock area lying within the relatively upwarping place in or on the margin of the volcanic belt.
