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.

A comprehensive review of experimental studies on shear behavior of bolted rock joints with varying rock joint and bolt parameters and normal stress

open access: yesDeep Underground Science and Engineering, EarlyView.
This study reviews the research findings on the shear behavior of bolted rock joints in deep underground engineering, where they face high stress, high water pressure, and engineering disturbance. This study examines how the shear strength of bolted rock joints is affected by various factors, such as normal stress, rock compressive strength, joint ...
