Synthetic Lignin Oligomers: Analytical Techniques, Challenges, and Opportunities

ChemSusChem, EarlyView.
The review begins by discussing lignin and its structural complexity, followed by challenges in elucidating depolymerization products and the analytical techniques used. It then focuses on the chemical structure of synthetic lignin oligomers, their synthesis mechanisms, and their significance in current science. Finally, scientific gaps are identified,

Testing the fidelity of zircon as a provenance indicator in fluvial‐fan successions: An example from the Palaeogene Colton Formation, Central Utah, USA

The Depositional Record, EarlyView.
This study integrates and expands the U–Pb detrital zircon dataset from the Colton fluvial system to highlight spatial variations in provenance signals within the early Palaeogene infill of the south‐western Uinta Basin, in Utah. The provenance data sheds light on the origin of clastic sediment and on the relationship with potential palaeodrainage ...

Interglacial dust, ocean fertilisation and Neoproterozoic earth oxygenation

The Depositional Record, EarlyView.
Mineral dust is an integral part of modern ocean nutrient supply. It is originated mainly in deserts and by glacial processes. Given the global scale of the Neoproterozoic glaciations, we suggest that mineral dust formed during snowball events were blown to oceans, sustaining life, promoting CO2 sequestration and contributing to the oxygenation of ...

The role of refluxing deep hypersaline brines and evaporite precipitation dynamics in the Castile Formation and marginal carbonate strata (Delaware Basin, USA)

The Depositional Record, EarlyView.
The Upper Permian Castile Formation of the Delaware Basin, a 515.3 m (1690.6 ft) thick deep‐water evaporitic sequence dominated by anhydrite and halite, is the focus of this study. This study's sedimentological and geochemical analysis of cores from the basin's centre and margin reveals that dynamic reflux of deep hypersaline brines significantly ...

Nature, origin and significance of a clayey cave deposit: Relationship between karst and Oligocene/Miocene tephra (NW Dinarides)

The Depositional Record, EarlyView.
A limestone cave in the NW Dinarides exhibits an anomalous presence of montmorillonite clay, not commonly found in surrounding caves, posing questions about its origin and age. Analysis reveals a composition similar to weathered tephra from the Smrekovec Volcanic Complex, suggesting transport by north‐east winds.
