OBJECTIVES
The SZNet Field Trip aims to foster collaboration among scientists of different nationalities and career stages and offer an opportunity for team-based field data collection. Participants will learn about the geology of the southern Cascadia subduction zone through data collection in an array of field locations and learn how to think about data across scales and methods.
Description
DATES: July 21-30 2024
​
WHAT: A 9-day interdisciplinary international field trip and data collection opportunity in the southern Cascadia arc and forearc near Ashland Oregon, USA.
FUNDING: Participant support for travel, food, lodging and field supplies is available through SZNet which is supported by funding from the National Science Foundation AccelNet program under award 2301732.
THEME: Linking field geological relationships, petrologic, structural, geochemical, petrophysical properties, and geophysical properties in the volcanic arc and forearc.
GOALS: Learn about the geology of the southern Cascadia subduction zone through data collection in an exhumed pluton and field trips to Crater Lake National Park, an accreted oceanic plateau, and a paleo subduction fault interface; Collect interdisciplinary field data as a team; Learn how to think about data across scales and methods; Evaluate effective methods for team-based field data collection.
DATA COLLECTION: Participants will undertake interdisciplinary team-based data collection activities involving geologic mapping, petrologic sample collection, geochemical analyses, and a nodal geophysical deployment in a Jurassic pluton near Ashland, Oregon. Outcomes of field data collection will be assembled into an AGU abstract, and participants are encouraged to use data and samples for their own post-field research.
WHO SHOULD APPLY: Open to both US and non-US scientists at any career stage interested in cross-disciplinary approaches to researching subduction systems. Those with experience or interest in petrology, structural geology, geochemistry, geophysics, deformation experiments, and modeling are encouraged to apply.
APPLICATION REQUIREMENTS: Applications are now closed and participants will be notified in April. Applications will be reviewed based on the following rubric
Scientific Background
The July 2024 SZNet trip will take place in the south/central Cascadia subduction zone and include:
​
a) Field trips from the volcanic arc at Crater Lake National Park to the accreted oceanic complex of the Siletzia terrane
b) Geologic and geophysical data collection in the Ashland Pluton, an exhumed Jurassic pluton located in the eastern portion of the Klamath Mountains
​
Field trips will provide participants with an introduction to the geology and volcanology of the central/southern Cascadia subduction zone, and regional context for their data collection activities. Data collection activities will focus on testing common assumptions about variability in pluton composition and relationships to seismic velocity models, at the Ashland pluton. Data and outcomes from the trip will be synthesized into an abstract for presentation in the Fall 2024 American Geophysical Union meeting. Participants are encouraged to use samples and data collected on this trip in complementary research projects.
