Building the Andean Crust at ∼35°S: Arc Geochemistry Reveals Cretaceous Thinning and Rapid Neogene Thickening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Quantification of the timing and mechanisms of crustal thickening in Cordilleran orogenic hinterlands remains challenging. We address this in the Andes using whole‐rock geochemistry and zircon petrochronology from a >70 Myr volcanic record in the Tinguiririca valley of Chile (∼35° ${}^{\circ}$S), which captures a pivotal transition from ...

Orbital Control of Reticulofenestra (Calcareous Nannofossils) Assemblages During the Early Pliocene

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Orbital changes have shaped Earth's climate system and influenced the evolution and spatial distribution of marine plankton, including coccolithophores. Some studies have assessed eccentricity's impact on the diversity and morphological evolution of Noelaerhabdaceae taxa during the Quaternary.

Precession‐Related Variability in North Pacific Deep Water Formation in the Early Eocene: Insights From cGENIE Simulations

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Past warmhouse climates differed from the modern ocean circulation regime, with deep‐water formation occurring in regions that are inactive today. Evidence suggests that the North Pacific may have been one such region. The early Eocene, characterized by elevated greenhouse gas concentrations and orbitally paced carbon cycle perturbations ...

Preserved Through Hyperaridity, 150 Million Years of Exhumation and Strike‐Slip Deformation in the Atacama Coastal Cordillera

Tectonics, Volume 45, Issue 9, September 2026.
Abstract The Coastal Cordillera of northern Chile, in the forearc of the Andean subduction zone, provides an ideal site to evaluate exhumation above the oldest active subduction under extreme aridity. This range lies parallel to a sediment‐starved trench, has experienced hyperaridity since the Miocene, and is transected by the ∼1,000‐km‐long Atacama ...
