An optimization tool for identifying multiple-diffusion domain model parameters [PDF]
GeochronologyThe multiple-diffusion domain (MDD) model empirically describes the diffusive behavior of noble gases in some terrestrial materials and has been commonly used to interpret 40Ar/39Ar stepwise degassing observations in K-feldspar.

Short communication: Nanoscale heterogeneity of U and Pb in baddeleyite from atom probe tomography – 238U series alpha recoil effects and U atom clustering [PDF]
GeochronologyAtom probe tomography (APT) of 238U and 206Pb has been applied to baddeleyite crystals from the Hart Dolerite (1791±1 Ma) and the Great Dyke of Mauritania (2732±2 Ma) in an effort to constrain the average nuclear recoil distance of 238U series daughter ...

Application of palynological data to the chronology of the Palaeogene lava fields of the British Province: implications for magmatic stratigraphy [PDF]
, 1997 New high-precision ages, determined from palynomorph assemblages within intercalated sedimentary deposits, are presented for the Palaeogene lava fields (Skye, Mull and Antrim) of the British Province. These data reveal very rapid averaged eruption rates (

Geological processes shaping freshwater biodiversity: a synthesis of global evidence
Biological Reviews, Volume 101, Issue 3, Page 1568-1581, June 2026.ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

The Depositional Record, Volume 12, Issue 3, June 2026.We document meter‐scale antidune and cyclic‐step deposits in channel–lobe transition zone (CLTZ) deposits of the Upper Cretaceous Point Loma Formation in San Diego, California. These results provide new insights into sediment transport dynamics in CLTZ environments, which are critical for understanding reservoir connectivity and heterogeneity in ...
