Revised Geology and Geological Structures of the Northeastern Chungnam Basin in the Southwestern Korean Peninsula

The Chungnam basin is a crucial area for studying the Mesozoic crustal evolutionary history of the Korean Peninsula. This study reports the revised geology and new isotopic ages from the northeastern Chungnam Basin based on detailed geological mapping and LA-ICP-MS zircon U-Pb analysis. Our renewed geologic map defines intra-basin, basin-bounding, and basement fault systems closely related to hydrothermal gold-bearing quartz vein injections. Here, we propose the directions of (micro)structural and geochronological future work to address issues on the relationship between the tectonic process, basin evolution, and hydrothermal fluid migration in the southwestern Korean Peninsula.

This study presents the revised geology and new isotopic ages of the northeastern Chungnam Basin. Future work on (micro)structural and geochronological analysis is proposed to further understand the relationship between tectonic processes, basin evolution, and hydrothermal fluid migration in the southwestern Korean Peninsula.
