Monday June 24 - Field trips and workshops
Please register in advance for these events. Field trip and workshop registration opens April 22.
Field trip: Structural and tectonic evolution of accreted oceanic rocks in the San Juan Islands, WA (all day).
Trip leaders: Liz Schermer, Sean Mulcahy (WWU). This trip will focus on deformed oceanic rocks that were subducted and accreted to the margin of North America during Cretaceous time. We will examine the different styles of deformation in accretionary wedge and ophiolitic rocks, and the contractional and strike-slip deformation recorded in the Lopez structural complex along a major terrane boundary. The trip will involve a ferry ride to Lopez Island, several short walks (up to 1.5 mi RT) on trails, optional walking on rocky tideland outcrops, and roadside stops. Depart 8 a.m. Boxed lunch provided. Return ~ 6:30 p.m. Limited to 25 participants.
Workshop: Magnetic Fabrics (afternoon).
Workshop leads: Cristina Garcia-Lasanta (WWU), Bernie Housen (WWU), Peter Selkin (UWT). The anisotropy of magnetic susceptibility (AMS) and other anisotropic rock magnetic characteristics are useful proxies for petrofabric with a variety of structural applications, from determining strain histories in deformed rocks and sediments to reconstructing pluton emplacement. In this workshop, we will introduce you to the rock magnetic techniques commonly used to evaluate fabric, with an emphasis on fabrics of ultramafic rocks. The workshop will include an opportunity to collect and process magnetic fabric measurements and discussion of the benefits and limits of AMS and rock magnetism as structural tools.
Two part ultramafic extravaganza: (You can sign up for Part 1, Part 2, or both).
Part 1 (morning): An accessible field trip to the Twin Sisters dunite quarry. (Ok, really, it is mostly a lherzolite.) Trip lead: Basil Tikoff (UWisc). The quarry on the north side of the Twin Sisters massif is generally not available to the public. We will examine relatively fresh ultramafic rocks (the rocks are green) and discuss fabrics throughout the Twin Sisters ultramafic body. We will drive right up to the outcrop. Limited to 25 participants.
Part 2 (afternoon, on campus): An informal hands-on workshop for studying ultramafic rocks. Workshop lead: Julie Newman (TAMU). We will provide ultramafic rock hand samples and thin sections from around the world, including ultramafic ultramylonite zones. Others are invited to bring their own samples, thin sections, and/or images, and share your observations in the discussion. Magnetic fabrics of samples can be measured. Participants are encouraged to share thin section images and associated data using the StraboMicro app.
Evening programming TBD [More information to come].

Thursday June 27 - Field trip and workshop
Please register in advance for these events. Field trip and workshop registration opens April 22.
Field Trip: Structure and Rheology of a Deep-Crustal Arc During Two Magmatic Flare-Ups: Skagit Gneiss Complex, North Cascades.
Trip leaders: Stacia Gordon (UNR), Bob Miller (SJSU). We will focus on the partially migmatitic Skagit Gneiss Complex, examining its structural and rheological response during partial melting and two magmatic flare-ups, one coincident with transpression and the other with transtension. Most of the planned stops are along a scenic highway in the North Cascades National Park Complex with one <500 m walk on mostly pavement. Depart 8 a.m. Boxed lunch provided. Retun ~ 8 p.m. Plan to have dinner on your own. Limited to 25 participants.
Workshop: All-day StraboSpot community input session.
Workshop leaders: Julie Newman (TAMU) & Basil Tikofff (UWisc). Be part of framing our collective digital future. We need community input on how we want to use digital data systems to enhance our future scientific goals. Topics include StraboMicro (including how to organize a search), Expert rules to automate Quality Assessment/Quality Control on projects, and Group Workflows (How do people want to work collaboratively in the field and the lab?). Note: We have NSF funds to cover lodging for two nights (Wed & Thu, June 26, 27) and all meals on June 27 for participants in the Strabo Workshop.
