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一个主要问题。该项目将调查阿巴拉契亚山脉南部陆架沉积物上方的蓝岭逆冲推力，它携带着水晶蓝岭和山前。这项工作将涉及与北卡罗来纳州祖父山窗口相关的矿脉材料的测绘、运动学研究和同位素研究。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合作完成的。这项研究将通过C、S、O、H和Sr的同位素比率来估计沿断裂带和其他大型垂直蚀变带切割蓝岭I型花岗岩的岩水比。结果应该提供了几种涉及流体存在的逆冲推覆模型的测试。

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.
