Dear basement geologists, If you're planning on heading to Seattle on October 22-25, 2017 to present on Precambrian tectonics research, we believe our session can provide a good home for you. T252. Cratonic Assembly in the Precambrian: Forming the Core of Modern and Ancient Landmasses This session strives to bring together a variety of disciplines - paleomagnetic, geochronologic, and geologic - to explain the movement and progressive assembly of individual Archean nuclei into ever larger larger landmasses. We hope you can join our session in Seattle; remember to get some sleep beforehand. Submissions are due August 1st, and are live at: http://community.geosociety.org/gsa2017/science-careers/sessions/topical The UF Paleomagnetics Group, Anthony Pivarunas, Joe Meert, and Scott Miller [log in to unmask]
