黑色页岩是对Mo元素具有极强地球化学敏感性的大洋沉积物类型之一。由于其通常具有异常高的Mo含量和98Mo/95Mo值,因此采用Mo同位素分析方法示踪黑色页岩被俯冲之后的演化过程是非常有效的。小安的列斯群岛的弧岩浆具有大陆来源的微量元素和放射成因同位素特征。但是其陆源地球化学特征究竟代表俯冲到大西洋板块并加
Black shales are one of the types of oceanic sediments that have a very strong geochemical sensitivity to Mo elements. Because of its generally high Mo content and 98 Mo / 95 Mo values, it is very effective to use the Mo isotope analysis method to trace the evolution of the black shale after its subduction. The Lesser Antilles arc magma has continent-derived trace elements and radiogenic isotopic characteristics. However, its terrigenous geochemical characteristics represent subduction to the Atlantic plate and add
