22 Everyday Geoscience (Posters)

This session will focus on elevating the importance of geoscience through geoscience education (e.g., curricula development, leading fieldwork experiences, etc.) and/or convergence research (e.g., using community-focused research frameworks/methods, community-engaged research, etc.).

Abstract

The National Science Foundation’s International Research Experience for Students (IRES) program (Awards #1658085, #2245854) has supported twenty-one New Mexico Highlands University students from Media Arts, Fine Arts, and Environmental Geology across five field seasons (2018, 2019, 2022, 2024, 2025) in northern Bohemia, Czech Republic. During the several field campaigns, the IRES groups sampled and worked on several trachyandesite intrusions related to the post-collisional extension-related magmatic activity developed within the Intra-Sudetic Basin during Early-Permian times. The apparent intrusive geometry includes laccoliths and sills emplaced along an accurate belt that rings the remains of an ignimbrite caldera that erupted the Góry Suche Rhyolitic Tuffs. Our research aims to better understand the complex geometries, emplacement dynamics, and connections between these trachyandesite intrusions exposed at various quarries in the region (i.e., Świerki, Dworki, Gardzień, Tłumaczów, Głuszyca). In this study, we concentrate on the exposures are the abandoned Świerki quarry. The Świerki intrusion appears as a single laccolith while others occur as stacked sills, and/or inclined sills crosscutting the intrusive rocks. Mining activities at the Świerki quarry provided a floor to ceiling exposure of a single laccolith which provides a tremendous opportunity to explore the variation of the magnetic properties throughout the sill. We compiled the results from anisotropy of magnetic susceptibility, paleomagnetic and rock magnetic experiments to visualize in three dimensions the variation of the magnetic properties within the intrusion. The ongoing exploitation at the Świerki quarry should offer additional insight into the emplacement and evolution of the late-Permian trachyandesite intrusions.
