SGER: Detailed Petrological Investigation of Cretaceous Oceanic Basalts from the Western Pacific

白垩纪玄武岩是在西太平洋的若干次深冲旋回中被发现的。这块地壳的年龄显然是异常的，如此巨大的地壳是如何形成的是一个难题。到目前为止，研究人员还没有处理这些样品，因为它们的变化程度很高，而且很难分析这些变化后的样品的同位素比率。PI将开发一种新的技术来分析它们，这些分析将最大限度地减少对化学成分的变化影响。将要收集的数据对于破译白垩纪地壳的起源(S)将是重要的。

Cretaceous basalts were recovered during a number of DSDP Legs form the western Pacific. The age of this crust is clearly anomalous and how such voluminous crust formed is a difficult problem. So far, researchers have not dealt with these samples because of their high degree of alteration and difficulty in analyzing such altered samples for their isotopic ratios. The PI will develop a new technique to analyze them and these analyses will minimize alteration effects on chemical composition. The data to be gathered will be important in deciphering the origin(s) of this Cretaceous crust.
