在远东各海盆的南缘和东缘,发育着处于不同构造位置的、主要是晚白垩世-新生代的火山带体系。在白令海,该体系是阿留申弧及其西段(科曼多尔群岛);在鄂霍次克海,为千岛岛弧;在日本海,为使马格列戈不斯克-契诃夫地堑东西两侧南部的结构复杂化,而后沿着北海道和本州岛的整个西部陆架延伸的晚第三纪火山杂岩体。这些火山带,有时还有它
In the southern and eastern margins of all the basins in the Far East, the Late Cretaceous-Cenozoic volcanic belt systems were developed in different tectonic positions. In the Bering Sea, the system is Aleutian arc and its western segment (Kemandor Islands); in the Sea of Okhotsk, it is the archipelago arc; in the Sea of Japan, in order to make Magliego-Vyshko-Chekhov Graben The structures on the south and east sides of the east-west are complicated, and later the Late Tertiary volcanic complexes extend along the entire western shelf of Hokkaido and Honshu islands. These volcanic bands sometimes have it
