Eocene - Near Trench Magmas with Jeff Tepper

Explore the fascinating world of Eocene magmatism in the North Cascades through this comprehensive lecture by CWU's Nick Zentner, featuring guest expert Jeff Tepper. Delve into the complexities of magmatic flare-ups, slab failure, and near-trench magmas (NTMs) as you journey through geological time. Examine the differences between Cretaceous, Eocene, and in-between plutons, and learn how to distinguish various types of magmas. Discover the unique characteristics of adakites and the Chimacum Rock formation. Engage with detailed geologic maps, photos, and animations that bring the North Cascades' geological history to life. Benefit from an extensive Q&A session with both Nick and Jeff, gaining deeper insights into this captivating subject.
