Description: Igneous activity in cordilleran orogens is inexorably linked with tectonic development and is a critical component of continental crustal evolution and construction. We invite talks that explore the character, origin and timing of magmatism and their links to the tectonic evolution of cordilleran orogens from a multi-disciplinary perspective.

T2. Structural Geology and Tectonics of the Western United States.
Stephen Martel, Univ. of Hawai‘i, smartelathawaii.edu; Ann Egger, Central Washington Univ., anneggeratgeology.cwu.edu.

Matthew McKay, Missouri State Univ., matthewmckayatmissouristate.edu; William Jackson, Univ. of Alabama/Geological Survey of Alabama, wjacksonatgsa.state.al.us; Keith Gray, Wichita State Univ., k.grayatwichita.edu.
Description: This session will explore the representation of magmatism and orogenesis in the sedimentary record. We encourage contributions that present innovative approaches for interpreting tectonic events using sedimentary strata, with topics including field mapping, structural analysis, sequence/seismic stratigraphy, paleoseismic features, tephrochronology, and quantitative analysis (geochronology, geochemistry, etc.).

T4. The Pacific Plate through Geologic Time. 
Paul Wessel, Univ. of Hawai‘i, pwesselathawaii.edu; Simon E. Williams, EarthByte, Univ. of Sydney, Australia, simon.williamsatsydney.edu.au.

The “ring of fire” and the Hawaii-Emperor Bend are consequences of its evolution and interaction with neighboring plates. This session welcomes submissions on topics related to the evolution of the Pacific plate.
