Book Description
This report presents 40Ar/39Ar sanidine ages and paleomagnetic data for 36 ignimbrites and associated lavas in the Eocene-Oligocene Mogollon-Datil volcanic field of southwestern New Mexico. 40Ar/39Ar age spectra from the ignimbrites yield plateau ages which range from 36.2 to 24.3 Ma and show within-sample and within-unit 1 s precision of ±0.5% or better. These ages agree closely with independently established stratigraphic order and indicate that Mogollon-Datil ignimbrite activity was highly episodic, being confined to four brief (

Book Description
Don Swanson, who received the GSA Mineralogy, Geochemistry, Petrology, and Volcanology Division's Distinguished Geologic Career award in 2016, has adopted a detailed, field-oriented approach to studying problems of great volcanologic importance across a range of compositions and spatio-temporal scales. Swanson's work has resulted in a series of fundamental contributions that have advanced understanding of the Columbia River flood basalts, Cascade volcanic arc, and Hawai'i, and his insights have been applied not only around the world, but across the solar system. This volume emphasizes the role of field volcanology as a window into better understanding volcanic processes past and present, and highlights, in particular, those places and processes where Swanson's insights have been particularly impactful.

Book Description
Papers based on geological mapping completed in the last 30 years and on associated stratigraphic and biostratigraphic studies deal with the contentious subject of correlation of Pennsylvanian units, and serve as an addendum to the work of Harold R. Wanless. Includes b&w photos and diagrams, and a g
