Stable Isotope Investigation of Solution Mass Transfer, Strain, and Fluid Flow in High-P Low-T Sandstones

已有多项研究报道了大体积应变，这些研究涉及到变形的推力楔形组件，但对质量传输的机制知之甚少。该项目将使用稳定的同位素地球化学和全岩成分数据来评估流体流动的作用，并确定流动的方向和数量。这些结果应该会进一步量化华盛顿西部晚白垩世圣胡安-喀斯喀特推覆体的体积应变，并提供对相关流体流动方向和大小的洞察。

Large volume strain has been reported from several studies involving deformed thrust wedge packages, but little is known about the mechanism of mass transport. This project will use stable isotope geochemistry and whole-rock composition data to assess the role of fluid flow and to determine the direction and quantity of flow. Results should further quantify volume strain in the late Cretaceous San Juan-Cascade nappes of western Washington and provide insight into the direction and magnitude of fluid flow responsible.
