Local and Regional Variation of MORB Parent Magma Compositions: Evidence from Melt Inclusions from the Endeavour Segment of the Juan de Fuca Ridge

小行星9503782 该项目将探索一种分析单个晶体中原始岩浆包裹体的新技术。 先前的研究发现，单晶体内部存在巨大的变异性，这意味着在一个小区域内产生的岩浆的变异性远比人们想象的要大。 该项目将检查一套岩石样本，这些样本来自沿着胡安·德富卡海岭的轴（以观察同一年龄的岩浆如何在晚期变化）和横跨轴（以观察单个岩浆房如何随时间变化）。 ***

9503782 Nielsen This project will explore a new technique in which inclusions of primitive magma within individual crystals are analyzed. Previous work has found great variability within a single crystal, implying that the magmas produced in a small area are far more variable than believed. The project will examine a suite of rock samples from along the axis of the Juan de Fuca Ridge (to see how magmas of the same age change latepally) and across the axis (to see how a single magma chamber changes over time). ***
