Within the Olyutorka–Kamchatka accretionary zone, several terranes of an island-arc, marginal-sea, and oceanic nature are distinguished. The igneous complexes of these terranes were formed within the active margin of the Western Pacific type. New data on the opening age of the marginal basins, as well as on the composition and age of the volcanic and terrigenous lithologic complexes of the terranes composing the Olyutorka–Kamchatka region, give grounds to propose a new refined model of the evolution of this region. The geodynamical reconstructions for the K2st-km1, K2km-m, and ₶1–₶2 times are presented.

Olyutorka-Kamchatka 增生带的白垩纪-早新生代地球动力学

在 Olyutorka-Kamchatka 增生带内，可以区分出几个岛弧、边缘海和海洋性质的地体。这些地体的火成岩杂岩形成于西太平洋类型的活动边缘。关于边缘盆地开放时代的新数据，以及构成奥柳托尔卡-堪察加地区的地体的火山和陆源岩性复合体的组成和时代的新数据，为提出该地区演化的新模型提供了依据. 给出了 K2st-km1、K2km-m 和 ₶1-₶2 次的地球动力学重建。
