​A Talk in Two Parts. (1) Overview of research to stimulate conversations; (2) Insights into the evolution of a subduction-accretion system, southern Alaska

​Event Type: Seminar

Event Date: 26 April 2019 - 4:00pm to 5:00pm

Venue: ASE 3D Viz Laboratory Room (N2-B1c-16c)

Speaker: Dr. Elisabeth Nadin

About the speaker:

Dr. Elisabeth Nadin, Associate Professor, University of Alaska Fairbanks

Structural Geologist/Tectonicist focusing on the strength of the lithosphere through fault-zone rheology and microstructures; also interested in arc assembly and accretion

BS -- University of Rhode Island, Geology & Geological Oceanography

PhD -- Caltech, 100-Myr evolution of an intrabatholithic fault

Postdoc -- Brown University, Strength with depth of an intrabatholithic strike-slip fault

Taught at: Pasadena City College, California State University Northridge, Eastern Connecticut State University. UAF since 2010. Co-director of EarthScope National Office.

About the event:

For the first half of my talk, I will briefly describe ongoing projects on 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.

For the second half of my talk, I will give a brief tectonic history of southern Alaska, which includes accretion of a Jurassic arc followed by it's 2-part accretionary complex. A brittle-ductile fault within the accretionary complex gives insights into fault strength in a subduction-zone environment.
