A Talk in Two Parts: Overview of research to stimulate conversations and Insights into the evolution of a subduction-accretion system, southern Alaska
About the Event:
The first half of the talk will focus on ongoing projects including: examining the strength evolution of a continental fault zone at the brittle-ductile transition; reconstructing an active arc volcano stratigraphy from eruption products; and determining wind patterns from detrital-zircon ages of loess deposits. The second half of the talk will focus on a brief tectonic history of southern Alaska, which includes accretion of a Jurassic arc followed by its two-part accretionary complex. A brittle-ductile fault within the accretionary complex gives insights into fault strength in a subduction-zone environment.
About the Speaker:
Elisabeth Nadin is an Associate Professor at the University of Alaska Fairbanks and has taught there since 2010. She is a structural geologist/tectonicist focusing on the strength of the lithosphere through fault-zone rheology and microstructures and is also interested in arc assembly and accretion. She studied geology and geological oceanography at the University of Rhode Island, where she received her Bachelor of Science. For her PhD at Caltech, Elisabeth's research focused on the 100-Myr evolution of an intrabatholithic fault. She her post doc at Brown University, where she researched on the strength with depth of an intrabatholithic strike-slip fault.
Elisabeth has also taught at Pasadena City College, California State University Northridge, and Eastern Connecticut State University. She is also co-director of EarthScope National Office.
