IODP Proposal 626: "Cenozoic Equatorial Age Transect – Following the Palaeo-equator"

As the largest ocean, the Pacific is intricately linked to major changes in the global climate system that took place during the Cenozoic. Throughout the Cenozoic the Pacific plate has had a northward component.

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

Ecography, Volume 2026, Issue 6, June 2026.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Dinosaur extinction can explain continental facies shifts at the Cretaceous-Paleogene boundary

Communications Earth & Environment
Continental Cretaceous-Paleogene boundary sections are best known from North America, where they invariably exhibit a marked shift in sedimentary facies at or very near the boundary level.

In-situ stress orientation and main controlling factors of deep shale reservoirs in the second member of Paleogene Funing Formation in Gaoyou Sag, Subei Basin

Shiyou shiyan dizhi
The shale oil resources in the second member of the Paleogene Funing Formation in the Gaoyou Sag, Subei Basin exceed 700 million tons. However, the complex geological conditions of both its structure and stress significantly impact the shale oil ...

Middle Cretaceous Andean‐Type Arc Evolution in the Sanandaj–Sirjan Zone (Shalair Valley), Iraq: New Geochronological and Geochemical Constraints

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The middle Cretaceous granitoid plutons of the Shalair Valley, situated in northeastern Iraq, constitute a principal magmatic component of the Sanandaj–Sirjan Zone within the northwestern segment of the Zagros Orogenic Belt. Among these plutons, the equigranular Aulan body (AG) and the porphyritic Laladar body (LG) were crystallized at 111.0 ±

Paleogene calcareous nannoplankton evolution: the fertility link

, 1992
Calcareous nannoplankton diversity varied greatly during the Paleogene. From extremely reduced values (~10 species) in the early Paleocene (circa 66.4 to 66 Ma, age estimates from Berggren, Kent and Flynn, 1985) following the terminal Cretaceous ...

Along‐Strike Seismic Structure of the Andreanof Aleutian Arc Segment and Implications for the Formation of Continental Crust

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Crust formed in volcanic arcs is accreted to continents over geologic time, serving as the source material for new continental crust in Earth's present and recent past. Geochemically, arcs are found to be significantly more mafic than bulk continental crust.

Accretionary Prism and Forearc Deformation Driven by the Beata Ridge Indentation in Southern Hispaniola: Insights From the Offshore San Pedro Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The Cretaceous–Eocene island arc of Hispaniola is currently shortened between the Bahamas carbonate platform to the north and the thickened crust of the Caribbean Large Igneous Province (CLIP) to the south. Within this transpressional setting, the 15–22‐km‐thick, ∼100‐km‐wide Beata Ridge (BR), the thickest portion of the CLIP, acts as a ...

Long‐Term Deformation in the Alpine‐Provence Foreland Constrained by In Situ Calcite U‐Pb Dating

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The evolution of the Alpine‐Provence foreland is characterized by multiple deformation phases since the Mesozoic, representing successive compressional and extensional episodes. The precise timing and spatial evolution of these deformation phases remain poorly constrained due to the lack of absolute geochronological data. Here, we present U–Pb
