Lacustrine and fan‐delta sediments in syn‐rift lake basins

open access: yesThe Depositional Record, Volume 11, Issue 3, Page 857-892, June 2025.
A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...

Geochemical evaluation of black limestones in the Early Cretaceous platform carbonates of Gümüşhane (NE Turkey): An insight into petroleum source rock potential and palaeoenvironment conditions

open access: yesThe Depositional Record, Volume 11, Issue 3, Page 917-953, June 2025.
Some layers of limestone produce some hydrocarbons, and these hydrocarbons are removed from the fractures and cracks of the rock. The organic matter (OM) contained in the limestone is a mixture of terrestrial and marine OM and is thermally immature and mature.

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

open access: yesThe Depositional Record, Volume 11, Issue 3, Page 954-974, June 2025.
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.
