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

大体积应变已报告从几个 涉及变形推力楔组件的研究，但很少 对物质传输机制的了解。 这 该项目将使用稳定同位素地球化学和全岩 成分数据，以评估流体流动的作用， 确定流动的方向和数量。 结果 应该进一步量化白垩纪晚期的体积应变 华盛顿西部的圣胡安-喀斯喀特推覆体， 洞察流体流动的方向和大小 责任

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.
