Extension and Mechanisms of High Temperature Deformation at Oceanic Rifts

该项目将侧重于获得与MORs伸展、正断层和岩浆侵入相关的偏应力和热参数的约束。这将通过校准作为应力函数的微观结构，然后将此信息应用于第3层辉长岩来完成。他们将采取多方面的方法，从微观结构的透射电镜研究，两种辉石的温度测量，到cpx和斜长石的高t变形实验。

This project will focus on obtaining constraints on deviatoric stresses and thermal parameters associated with extension, normal faulting, and magma intrusion at MORs. This will be done by calibrating microstructures as a function of stress and then applying this information to Layer 3 gabbros. They will take a multiprong approach that ranges from TEM study of the microstructures, thermometry of two pyroxenes, to high-T deformation experiments on cpx and plagioclase.
