Subduction Initiation Volcanism Leading to Development of the Talkeetna Arc, Lower Shuyak Formation, Kodiak Archipelago, Alaska

Tectonics, Volume 45, Issue 4, April 2026.
Abstract Our understanding of subduction initiation remains limited by the difficulty of making direct observations of geologically recent examples. In the geologic record, supra‐subduction zone ophiolites are often interpreted to record syn‐initiation slab rollback and upper plate extension. Unfortunately, many ophiolites are decoupled from records of

Late Jurassic Algae from Honshu and Shikoku, Japan

Late Jurassic Algae from Honshu and Shikoku, Japan
application/pdf Nine species in nine genera of Algae are described from the Upper Jurassic Soma series in Fukushima Prefecture and the Torinosu series in Kochi Prefecture. Among them the genus Polygonella is described for the first time from Japan. That genus is fairly common in the Jurassic of Iraq, Syria, Switzerland and Austria.

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)

Boreas, Volume 55, Issue 2, Page 454-475, April 2026.
Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Geochemical and Seismic Constraints on the Role of Mud Diapirs in Petroleum Migration and Accumulation in the Recôncavo Basin, NE Brazil

Journal of Petroleum Geology, Volume 49, Issue 2, Page 433-447, April 2026.
ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...

Population and herbarium genomics provide a comprehensive framework for a revision of Microcoleus (Cyanobacteria)

Journal of Phycology, Volume 62, Issue 2, Page 454-476, April 2026.
Abstract Microcoleus is a cosmopolitan, filamentous cyanobacterium and a key component of biological soil crusts—complex microbial communities essential for primary production in diverse terrestrial environments. Here, we performed a taxonomic revision of several species of Microcoleus based on a large population genomic dataset.

The effect of early diagenetic processes on the quantification of fossil micrometeorite abundance and flux in the geological record

Meteoritics &Planetary Science, Volume 61, Issue 4, Page 551-564, April 2026.
Abstract Fossil micrometeorites (MMs) recovered from lithified sedimentary rocks, particularly iron‐rich (I‐type) cosmic spherules (CSs) provide valuable insights into past dust‐forming events. Their abundances, when combined with estimates of local sedimentation rates can be used to reconstruct the flux of extraterrestrial dust.

No legacy effects of severe drought on carbon and water fluxes in a Mediterranean oak forest

Plant Biology, Volume 28, Issue 3, Page 671-683, April 2026.
A Mediterranean Quercus ilex forest was severely affected by a drought in 2017 but fully recovered in the following year, supported by favourable weather and growing conditions both before and after the event. Abstract Severe droughts affect vegetation through several processes, such as hydraulic failure, early leaf senescence, depletion of carbon ...
