RUI: Oxygen Isotope Studies of Hydrous Silicates in the Oceanic Lithosphere

该项目将与伍兹霍尔海洋研究所(WHOI)为布里奇沃特州立大学(BSC)的本科生建立一个合作研究计划。我们建议通过实验校准用于预测常见水合硅酸盐和铝硅酸盐与水之间氧同位素分馏系数的经验/理论模型。这些实验的结果将被用来通过对从缓慢扩张的大洋中脊环境中挖出的蚀变超镁铁质岩石进行氧同位素分析，来约束大洋岩石圈蛇纹岩的热历史。通过参与实验和实地研究，参与这个项目的学生将有机会体验如何使用两种截然不同的方法来支持科学问题的解决方案。该项目非常适合BSC跨学科地质学-化学项目的学生，所有基于实验室的研究都将在WHOI进行，为学生提供独特的研究环境和广泛的设施。

This project will establish a collaborative research program with the Woods Hole Oceanographic Institution (WHOI) for undergraduate students at Bridgewater State College (BSC). We propose to calibrate by experiment the empirical/theoretical models used to predict oxygen isotope fractionation factors between common hydrous silicates and aluminosilicates and water. The results of these experiments will be used to constrain the thermal history of serpentinization in the oceanic lithosphere through oxygen isotope analyses of altered ultramafic rocks dredged from slow spreading mid-ocean ridge environments. Through involvement in both experimental and field-based inquiry, students working on this project will have an opportunity to experience how two vastly different approaches are used to support the solution to a scientific problem. The project is ideally suited for students in the interdisciplinary geology-chemistry program at BSC and all laboratory based research will be conducted at WHOI, providing students access to a unique research environment and extensive facilities.
