Our GEOS255 Historical Geology class visited the Grand Canyon in Northern Arizona to learn about Earth’s geologic history. We camped over the weekend, cooked and hiked together, and composed mnenomics to remember the sequence of Grand Canyon strata. The field trip was led by co-instructors Dr.Barbara Carrapa and Dr.Jonny Wu….Continue Reading Historical Geology class field trip to Grand Canyon
Congratulations to Chris Calvelage, who led a paper on “Effects of subduction history on true polar wander driven by perturbations of Earth’s inertial moment from mantle convection” that was accepted in the journal Proceedings of the Royal Society A. Co-authors are Lorenzo Colli, Jonny Wu, Yi-An Lin, Yingcai Zheng, and Moloud Rahimzadeh Bajgiran. Open Access…Continue Reading New paper on True Polar Wander and subduction history

The Geodaze student-run research symposium was held at University of Arizona on Mar 27-29, 2025. Our group members presented the following topics: Parker Comisac (MS Student): “Unfolding the Alaska-eastern Aleutians slab and its implications for Kula-Pacific plate tectonic reconstructions” Will McCraine (MS Student): “Discoveries from a geologic traverse across a metamorphic core complex along Tanque Verde…Continue Reading UA Geodaze 2025 presentations
Welcome to Dr.Ed Clennett, who is conducting research on Pacific plate tectonics, critical minerals, and machine learning. Ed completed his PhD at UTexas Austin, USA, and worked on seismic tomography, geodynamics and plate kinematic modeling. Ed’s MS was completed at Oxford University, UK, where Ed developed a plate reconstruction of western North America and the…Continue Reading Welcome to Dr.Ed Clennett
