Under this funding, the PI will use in situ analyses of minerals from both extrusive and intrusive rocks (collected from the Mid-Atlantic Ridge near the Kane Transform Fault and the Southwest Indian Ridge near the Atlantis II Fracture zone) to understand magmatic construction processes. Data will be collected using Laser-Ablation Inductively-Coupled-Plasma Mass- Spectrometry (LA ICPMS). This study will provide insight into the magmatic system over three different spatial scales and will test a number of ideas regarding the petrogenesis of deep crustal rocks, how they were emplaced, how they crystallized, and under what physical conditions.

在这笔资金的资助下，PI将使用对喷出岩和侵入岩（从凯恩转换断层附近的大西洋中脊和亚特兰蒂斯II断裂带附近的西南印度洋脊收集）的矿物进行原位分析，以了解岩浆建造过程。将使用激光消融电感耦合等离子体质谱法（LA ICPMS）收集数据。这项研究将提供深入了解岩浆系统在三个不同的空间尺度，并将测试一些想法，深地壳岩石的岩石成因，他们是如何安置，他们如何结晶，在什么样的物理条件。
