Canadian geophysicist Tuzo Wilson realized that this age progression could result if the islands were formed on a surface plate moving over a fixed volcanic source in the interior.

加拿大地球物理学家 Tuzo Wilson 意识到，如果一块在内部固定火山源上移动的表面板块形成了岛屿，就会导致岛屿年龄增加。

The oceanic volcanic islands and their hot-spot trails are thus especially useful for geologists because they record the past locations of the plate over a fixed source.

海洋火山岛和它们的热点轨迹对于地质学家尤其有用，因为它们记录了过去的板块在固定地点之上的位置。

Wilson suggested that the long chain of volcanoes stretching northwest from Hawaii is simply the surface expression of a long-lived volcanic source located beneath the tectonic plate in the mantle.

威尔逊认为，夏威夷向西北延伸的火山长链只是一个长期存于板块下、地幔中的火山源在板块表面的表现。
