Refletions on the Recôncavo Series, Brazil [PDF]

open access: yesAnuário do Instituto de Geociências, 2018
Chronostratigraphic units are of prime importance in geology. Their limits provide the basis for reliable chrono-correlations, both locally and globally.

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 ...

Orbital chronostratigraphy of the Valanginian-Hauterivian boundary. A cyclostratigraphic approach

open access: yes, 2004
Based on cyclostratigraphy and sequence stratigraphy criteria, an orbital chronostratigraphy is here proposed for the Upper Valanginian/Lower Hauterivian (Lower Cretaceous) stratigraphic interval.

Depositional Setting of Eastern Sakarya Zone (NE Türkiye): Late Cretaceous–Paleogene Period Biostratigraphy, Sedimentology and Tectono‐Sedimentary Basin Evolution

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
K‐Pg transition and Maastrichtian stage of sedimentary basin evolution of the Eastern Sakarya Zone. ABSTRACT This study reconstructs the late Campanian–Thanetian tectonic and sedimentary evolution of the Eastern Sakarya Zone Basin (Türkiye) during the closure of the Neotethys Ocean, through the integration of tectonic, biostratigraphic and sedimentary ...

Multi‐Proxy Thermal History of Basin Heating During Cordilleran Orogenesis in the Magallanes‐Austral Retroarc Foreland Basin, Patagonian Andes

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
Paleogene unconformity development from ~64 to 22 Ma for the Magallanes‐Austral retroarc foreland basin (MAB). Schematic shows (A) MAB foreland subsidence and basin infilling, (B) onset of cooling and basin inversion as subducting plate shallows, (C) continued foreland uplift, erosion and cooling as the oblique Farallon‐Phoenix ridge subducts beneath ...

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

open access: yesArchaeology in Oceania, Volume 61, Issue 1, Page 128-161, April 2026.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

A Revised Cenozoic Geochronology and Chronostratigraphy

open access: yes, 1995
Since the publication of our previous time scale (Berggren and others, 1985c = BKFV85) a large amount of new magneto- and biostratigraphic data and radioisotopic ages have become available. An evaluation of some of the key magnetobiostratigraphic calibration points used in BKFV85, as suggested by high precision 40Ar/39Ar dating (e.g., Montanari and ...

Graman Revisited Once Again: A Reanalysis of the Late Holocene Legacy Faunal Assemblage From GB4 Rockshelter, New South Wales

open access: yesArchaeology in Oceania, Volume 61, Issue 1, Page 199-220, April 2026.
ABSTRACT The archaeological site Graman B4 provided one of the first records of substantial dietary change in ancient Australian Aboriginal society. Initial examination of the faunal remains from this site suggested that Late Holocene hunters reduced their focus on high‐ranked kangaroos to increasingly rely on arboreal possums; and that these ...
