Lower Eocene sedimentary succession and microfossil biostratigraphy in the central northern Caucasus basin

open access: yesGeologica Acta, 2020
The lower Eocene sediments from the classical Paleogene section exposed along the Kheu River, northern Caucasus, southern Russia are here studied. This ca. 50m thick succession is lithologically contrasting: the lower and upper parts are composed by soft

Human Activities, Biostratigraphy and Past Environment Revealed by Small-Mammal Associations at the Chalcolithic Levels of El Portalón de Cueva Mayor (Atapuerca, Spain)

open access: yesQuaternary, 2021
The Chalcolithic levels of El Portalón de Cueva Mayor (Atapuerca, Burgos, Spain) offer a good opportunity to test whether the small-mammal contents of different archaeo-stratigraphical units may be useful to characterize them as independent entities ...

Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
New U–Pb zircon dating shows the Rewan Group was deposited between ~250 and 233 million years ago and that sedimentation shifted across the basin through time, with earlier deposition in the foredeep and later deposition in the back bulge. Testing multiple dating approaches and grain‐selection strategies improves confidence in these age estimates and ...
