Abstract
<jats:p>Cathy Busby was awarded GSA’s Division of Mineralogy, Geochemistry, Petrology, and Volcanology’s Distinguished Career Award in 2020. In 2022, the editors of this volume convened a session at the GSA Connects meeting to honor her and then encouraged session participants to contribute to this volume. The papers range in scope from petrology to facies analysis to sedimentation, and they span time from Permian to Holocene, and space from Mexico and California to Taiwan and Izu-Bonin. Many are focused on parts of the North American Cordillera, and they are ordered from north to south (from Lassen Peak, California, to Michoacán, México). Papers from the western Pacific Ocean follow these, and this final section also includes process and textural studies. All of the papers celebrate Busby’s dedication to fieldwork as the foundation for geological studies.</jats:p>
