Variations in downslope activity and bottom current dynamics in a land‐detached submarine channel system since the Last Glacial Maximum

Sedimentology, Volume 73, Issue 3, Page 620-644, April 2026.
ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.

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 ...

Long‐Term Storage of Meteoric Water in the Variscan Basement: Stable Isotope Constraints (δD–δ18O)

Terra Nova, Volume 38, Issue 2, Page 116-123, April 2026.
ABSTRACT F‐Ba‐Pb‐Zn (±Ag) deposits near the unconformity between the Armorican and Aquitaine basins formed by mixing surface waters and brines with fluid ascending from the basement. To better constrain the source of this fluid and the conditions of mixing, we analyzed the hydrogen (δDwater) and oxygen (δ18Owater) isotopic composition of water trapped ...
