向东扩延的墨西哥火山带是由钙碱性和大洋岛屿玄武岩（以下简称ＯＩＢ）类火山岩组成的，其成因和演化还是个谜。支持该火山是由于消减作用而产生的主要证据是因为它有着经典板块构造背景，与消减性大洋板块有关（Ｃｏｃｏｓ及Ｒｉｖｅｒａ板块），而且带内大部分熔岩具备...

The main evidence supporting the volcano is its abatement because of its classic plate tectonic setting associated with subducting oceanic plates (Cocos and Rivera plates), and most of the lava in the belt ...
