Cenozoic Tectonic Transitions and Lithospheric Evolution Along the Colorado Plateau- Basin and Range Boundary in Central Arizona

该项目是横跨科罗拉多、高原-盆地和山脉边界的地壳和岩石圈新生代演化的跨学科研究。将评估这一主要构造边界上地壳和岩石圈厚度的横向变化及其与大陆地壳伸展的关系。两个样带将通过：地质填图和构造地质学进行研究；沉积学、地层和裂变径迹分析；以及火山、岩石学和地球化学分析。研究结果将提供对大陆伸展过程的深入了解，并将与其他地区的许多其他伸展构造制度直接相关。

9417901 Reynolds This project is an interdisciplinary study of the Cenozoic evolution of the crust and lithosphere across the Colorado, Plateau-Basin and Range boundary. Lateral changes in crustal and lithospheric thickness across this major tectonic boundary, and their relationship to the extension of continental crust, will be assessed. Two transects will be studied by: geologic mapping and structural geology; sedimentological, stratigraphic and fission track analysis; and volcanic, petrologic and geochemical analyses. The results will provide insight into continental extensional processes and will have direct relevance to many other extensional tectonic regimes elsewhere.
