Explore the fascinating world of Eocene geology in this comprehensive lecture by CWU's Nick Zentner, featuring guest speaker Spencer Fuston. Delve into the complexities of North Cascades geology, focusing on the Resurrection Plate and its implications. Learn about offshore vs. onshore geology, near-trench magma clusters, and the Chugach translation. Examine slabs and plates through seismic tomography, with detailed discussions on the Alaska and Cascadia slab map, Yukon slab, and detached slabs. Witness plate reconstruction animations and understand the significance of the Resurrection Plate in geological history. Engage in an extensive Q&A session covering topics such as the absence of a plate under British Columbia, future research on lower mantle slabs, and the dangling slab under Idaho. Gain insights into Near Trench Magmatism (NTM) locations and ages, providing a thorough understanding of this crucial period in Earth's geological past.
