Growth and reworking of freshwater microbially‐mediated carbonates in wind‐stressed lake margins (Lago Sarmiento, Southern Patagonia)

Sedimentology, Volume 73, Issue 3, Page 706-741, April 2026.
ABSTRACT Understanding the biotic and abiotic influences on the deposition and diagenesis of recent microbial carbonates is crucial for addressing the environmental and ecological significance of ancient organosedimentary structures. This study investigates these factors and their expression in the microstructure of Holocene tufa thrombolites from a ...

The making of pure quartzose sand in continental interiors: Paraná River (Brazil and Argentina)

Sedimentology, Volume 73, Issue 3, Page 802-837, April 2026.
ABSTRACT As part of a comprehensive project on sedimentary processes in South America, this study focuses on sediment generation in the intracratonic Paraná Basin and monitors the evolution of sand composition along the Paraná River from central Brazil to the Río de la Plata estuary in Argentina.

Phylogenomics illuminates the complex evolutionary history of Bibionomorpha (Diptera)

Systematic Entomology, Volume 51, Issue 2, April‐June 2026.
Phylogenomics supports Bibionomorpha (Anisopodoidea, Bibionoidea, Scatopsoidea, Sciaroidea) as a sister to Brachycera, and Axymyiidae and Perissommatidae as a sister to Bibionomorpha + Brachycera. Phylogenetic network analysis tentatively suggests a possible reticulation leading to Bolitophilidae, and mitochondrial data support sex‐specific ...

New Phoenix Magnetic Anomaly Data Confirms Global Nature of Jurassic Quiet Zone and Provides Insight Into Early Pacific Spreading

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We demonstrate the presence of the oldest identifiable marine magnetic anomalies in the Phoenix lineations of the western Pacific based on careful assessment of new data. Recently acquired sea surface magnetic anomalies and multichannel seismic profiles confirm magnetic signals recorded within the Middle‐Jurassic to Early Cretaceous basement ...
