COLLABORATIVE RESEARCH: Fluid Flow in the Grandfather Mountain Window, North Carolina: Structural and Tectonic Implications

流体在推力中的作用仍然是主要关注的问题。这个项目将调查蓝岭冲断带，它携带着水晶蓝岭和皮埃蒙特在阿巴拉契亚山脉南部大陆架上的沉积物。这项工作将涉及与北卡罗来纳州祖父山窗口相关的矿脉物质的测绘、运动学研究和同位素研究。通过C、S、O、H和sr同位素比值的组合，将沿断裂带和其他在蓝岭切割i型花岗岩的大规模垂直蚀变带估算岩水比。这项研究是路易斯安那州立大学、北卡罗来纳大学和威斯康星大学的工作人员共同努力的结果。结果应提供涉及流体存在的几种逆冲模型的测试。

The role of fluids in thrusting continues to be of major concern. This project will investigate the Blue Ridge Thrust which carries the crystalline Blue Ridge and Piedmont over shelf sediments in the Southern Appalachians. The work will involve mapping, kinematic studies and isotopic studies of vein material associated with the Grandfather Mountain Window, North Carolina. Rock-water ratios will be estimated along the fault zone and also on other large-scale vertical alteration zones which cut I-type granites in the Blue Ridge by a combination of isotopic ratios of C, S, O, H and Sr. This study is a collaborative effort between workers at Louisiana State University, University of North Carolina and the University of Wisconsin. Results should provide a test of several models of overthrusting that involve the presence of fluids.
