RUI: COLLABORATIVE RESEARCH: Structural and Petrologic Studies of the Tenpeak Pluton and Surrounding Area, North Cascades: A Window into Arc Processes in the Mid to Lower Crust

喀斯喀特岩心的构造环境仍有争议，特别是白垩纪弧发育期间高品位岩石的装载方式和相关的岩浆事件。大陆弧深部地壳岩浆作用的几种模式已经提出，但由于缺乏深部地壳的暴露，这些模式的适用性受到了有限的限制。该项目将重点研究喀斯喀特岩心中最大的暴露最深的十峰岩体的构造、变质、成岩和地球化学过程。研究结果有望阐明岩浆在形成深部岩体中的作用，为深入了解地壳侵位机制提供见解，并使人们更好地了解喀斯喀特弧的演化和加载历史。

9628280 Miller The tectonic setting of the Cascades Core remains controversial, particularly the manner in which the high grade rocks were loaded during te development of the Cretaceous arc and the associated magmatic events. Several models of magmatic processes in the deep crust of continental arcs have been advanced, but the lack of deep crustal exposures have provided only limited constraints for the applicability of these models. This project will focus on the structural, metamorphic, plutonic and geochemical processes operating in the Ten Peak pluton, which is the deepest exposed pluton of significant size in the Cascades Core. Results are expected to clarify the role of mafic magmas in generating the pluton, to provide insights into deep crustal emplacement mechanisms and to allow a better understanding of the evolution and loading history of the Cascade arc.
