Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

Archaeometry, Volume 68, Issue S2, Page S104-S129, May 2026.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

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

Basin 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 ...

Timing of Metamorphism and Deformation in the Neoarchean Quetico Metasedimentary Belt, Superior Craton, Constrained by Garnet Trace‐Element Mapping and Lu–Hf Geochronology

Journal of Metamorphic Geology, Volume 44, Issue 4, Page 265-286, May 2026.
ABSTRACT The Quetico subprovince of the Superior Province is among the largest metasedimentary belts globally and provides evidence of tectonic processes at play during the final stages of Archean cratonization. Although previous studies have shown that deformation and metamorphism of the 2.7‐Ga turbiditic protolith resulted in regional subvertical ...

Modelling Reveals an Ice Field on the Arid Northeastern Tibetan Plateau During Marine Isotope Stage 6

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The long‐standing hypothesis that an ice sheet covered the Tibetan Plateau during the Last Glacial Maximum (LGM) has been refuted. Further research has indicated that the Plateau experienced more extensive glacial expansion during Marine Isotope Stage (MIS) 6 than during the LGM.

Earthtime [PDF]

, 2010
Quantification of geological time represents one of the fundamental challenges for earth scientists as it permits the determination of rates of change, integration of disparate geological datasets and assessment of coincidence (or lack thereof) so ...

Fe–Mn Crust δ98Mo Decline Records Tectonic Forcing on Marine Oxide Sink Reduction During the Early Eocene–Early Oligocene

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract S, Tl, and W isotope records document pronounced early Eocene shifts in marine redox, yet the absence of a Mo isotope record obscures its progression. Here, we present ∼80 Myr Mo–Os–Be–Nd isotope profiles from a Northwest Pacific hydrogenetic Fe–Mn crust, revealing a systematic δ98Mo decline from −0.24‰ (early Eocene) to −0.83‰ (early ...
