Dear Colleagues, Please consider submitting to our volcanic-plutonic themed session at the GSA Cordilleran Section Meeting in Sacramento, CA, April 1-4, 2025: T14. Volcanic and Plutonic Connections in Cordilleran Arcs: Integrating Studies from Extinct and Active Systems This session investigates how volcanic and plutonic systems are related in Cordilleran arcs. We welcome studies on volcanic and plutonic rocks and porphyry systems of active and extinct arcs, which use various methods such as field observations, modeling, experiments, and geochemical and geophysical techniques to gain insights into the volcanic-plutonic connection. Submit an abstract: https://gsa.confex.com/gsa/2025CD/top/papers/index.cgi?sessionid=57564 The abstract deadline is January 28, 11.59 PM Pacific Time, just over two weeks from now. We encourage submissions from a broad range of fields and look forward to hearing about your research! Katie Ardill and Madeline Lewis
