Nature, origin and significance of a clayey cave deposit: Relationship between karst and Oligocene/Miocene tephra (NW Dinarides)

open access: yesThe Depositional Record, EarlyView.
A limestone cave in the NW Dinarides exhibits an anomalous presence of montmorillonite clay, not commonly found in surrounding caves, posing questions about its origin and age. Analysis reveals a composition similar to weathered tephra from the Smrekovec Volcanic Complex, suggesting transport by north‐east winds.

Water pathways and ancient lakes: Flowing towards new models to unravel the past

open access: yesThe Depositional Record, EarlyView.
Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.

Contributions of arid climate and hydrothermal fluid flow on sedimentation in saline‐alkaline lakes: Insight from the Ibar intramontane basin (Southern Serbia)

open access: yesThe Depositional Record, EarlyView.
The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...

CO2 Storage Site Selection: A Comprehensive Review of Current Approaches

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Global warming, driven by increasing anthropogenic greenhouse gas emissions, has emerged as a critical environmental concern. Carbon capture and storage (CCS) technology offers a promising solution for reducing CO2 emissions, but its effectiveness depends on identifying suitable candidates that can ensure safe, long‐term storage of CO2.

Application of 3D Raman Mapping on Complex Inclusions: A Case Study of the Styrian Basin Mantle Xenoliths (W‐Carpathian Pannonian Region)

open access: yesJournal of Raman Spectroscopy, EarlyView.
Recent advancements in spectral and spatial resolutions for Raman spectroscopy allow the analysis of fluid and melt inclusions. To explore the applicability of 3D Raman mapping, we conducted 3D Raman mapping on inclusions hosted by orthopyroxene in modally metasomatized mantle xenoliths from the Styrian Basin (W‐Carpathian Pannonian Region).
