Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

Diagenesis and reservoir quality of the Lower and Middle Buntsandstein (Lower Triassic), SW Germany

open access: yes, 2015
This research work deals with the diagenesis and reservoir quality of the Lower Triassic Buntsandstein in south-western Germany. The Buntsandstein in the study area is a continental succession with mostly fluvial and subordinately lacustrine and aeolian sediments.

Columnanidus calitzdorpensis ichnogen. ichnosp. nov: A new Middle Pleistocene subterranean termite trace fossil from South Africa

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Termites are landscape geo‐engineers whose nesting activities substantially modify the physical and chemical properties of soils. Fossilised termite nests commonly constitute the only identifiable evidence of ancient termite activity and represent valuable trace fossil archives for reconstructing past environments.

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Aftermath of the Permian-Triassic mass extinction event: Paleoecology of Lower Triassic carbonates in the western USA

open access: yesPalaeogeography, Palaeoclimatology, Palaeoecology, 1995
Paleoecologic study of invertebrate faunas from three successive Early Triassic seaways reveals that biotic recovery from the end-Permian mass extinction event was slow, and that full recovery did not occur until after the Early Triassic. Simple, cosmopolitan, opportunistic generalists, and low-diversity, low-complexity paleocommunities were ...

Lateral discrepancies of cycle patterns in the Latemàr, Triassic, Italian Dolomites [PDF]

open access: yes
The well-known cyclic carbonate succession of the Middle Triassic Latemàr Massif in the Italian Dolomites reveals significant lateral variability in cycle numbers in platform-interior strata.
