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

9627986帕特森喀斯特地核的构造背景仍然存在争议，特别是在白垩纪弧体及其相关岩浆事件发展过程中高品位岩石的加载方式。已经提出了几种大陆弧深部地壳岩浆作用的模型，但由于缺乏地壳深部暴露，这些模型的适用性仅受到有限的限制。该项目将重点研究十峰岩体中的构造、变质、深成和地球化学过程，这是级联核中最深、最大规模的裸露岩体。预计结果将澄清镁铁质岩浆在形成岩体中的作用，提供对地壳深部侵位机制的见解，并使人们能够更好地了解级联弧的演化和加载历史。

9627986 Paterson 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.
