进入火山弧（例如夏威夷 -皇帝链）组分的群岛的分布特征和地质年龄有规律的增长 ,可以良好地用地壳构造板块在地幔中稳定的“热点”之上的等速运动来加以解释。较小规模的“热点”痕迹出现在断续散布的火山成因群岛山脊内 ,其分布与岩石圈厚度相适应。此外 ,这些山脊经常不形 The distributional characteristics of the islands entering the volcanic arc (eg, the Hawaiian-Emperor chain) component and the regular increase in geologic age can be well explained by the isokinetic movement of the crustal tectonic plate above the stable “hot spot” in the mantle. Smaller “hot spots” appear in intermittent volcanic-sourced archipelago ridges, with distribution consistent with lithosphere thickness. In addition, these ridges are often not shaped
