摘要

摘要分析了沿千岛-堪察加岛弧（KKIA）火山活动的起源。地球物理观测显示了板块参数的变化。板块倾角的变化造成了库里尔-堪察加半岛弧北部和南部火山带宽度的不同。布索尔海峡的裂谷系统可能是由 KKIA 中部板块速度的显著变化产生的。我们提出，弧后盆地在板坯各种参数的形成和 KKIA 沿岸火山活动的表现中起着主导作用。

The Role of the Back-arc Basin in the Formation of Slab Heterogeneity and the Origin of Volcanism in the Kuril–Kamchatka Island Arc

Abstract

The origin of volcanism along the Kuril–Kamchatka Island Arc (KKIA) was analyzed. Geophysical observations show variations in the slab parameters. Different widths of the volcanic belt in the northern and southern parts of the KKIA are caused by changes in the slab dip angle. The rift system of the Bussol Strait may be generated by significant changes in the slab velocity in the central segment of the KKIA. We proposed that the back-arc basin plays a predominant role in the formation of various parameters of the slab and manifestations of volcanism along the KKIA.
