New publication in The Depositional Record

We are pleased to announce the publication of a new article by Zupan Hajna, N., Bosák, P., Mihevc, A., Banaś, M., Filip, J., Krmíček, L. et al. (2025): Nature, origin and significance of a clayey cave deposit: Relationship between karst and Oligocene/Miocene tephra (NW Dinarides). The Depositional Record, 00, 1–21. Available at: https://doi.org/10.1002/dep2.70013

Highlight: A rare montmorillonite clay deposit was discovered in a cave above the Kras Plateau (“Classical Karst”). Geochemical analyses indicate that it originated from weathered volcanic ash of the Smrekovec Volcanic Complex, dating back over 20 million years. The findings provide strong evidence that a karst landscape already existed in the northwestern Dinarides by the end of the Oligocene. Cave sediments serve as valuable geological archives, offering insights into karst system evolution, volcanic activity, and environmental changes. https://onlinelibrary.wiley.com/doi/full/10.1002/dep2.70013
