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 ±

Sensitivity of Soil Chemical Erosion Rate to Climate and Dust Along a 2.8‐km Elevation Transect at San Jacinto Mountain, California

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Chemical weathering is of wide interest because it breaks down minerals, releases nutrients, weakens rock, and draws down atmospheric CO2. To quantify the sensitivity of soil chemical erosion rate to climate and dust, we measured soil chemical erosion rate, dust deposition rate, and soil climate at 18 ridgetop sites along a ∼2.8‐km elevation ...

Evidence for Limited Atmospheric CO2 Rise at the Miocene Climatic Optimum

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Miocene Climatic Optimum (MCO; 16.9–14.7 Ma) was a relatively warm period with atmospheric CO2 averaging ∼500 μatm but CO2 change across its onset is poorly documented. We present a record of algal 13C‐fractionation covering the Early to Middle Miocene (∼18.5–15 Ma), with a gap at the MCO onset, from Ocean Drilling Program Site 959 in the ...

Syn‐ to Post‐Collisional Tectonic History of the Paleo‐Tethyan Orogenic Belt: Insights From Triassic Igneous Rocks in the North–Central Tibetan Plateau, China

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The closure of the Paleo‐Tethys Ocean was one of the most important global geological events which formed the framework of the East Asian continent during the early Mesozoic. The Longmu Co‐Shuanghu suture zone is considered to record closure of the main basin of the Paleo‐Tethys Ocean.

Transformation of Refractory Oceanic Lithospheric Mantle by Reactive Melt Infiltration: An Experimental Study on the Roles of Temperature, Melt Volume and Ascent Velocity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Reactive melt infiltration critically modifies the physical and chemical properties of the oceanic lithospheric mantle (OLM). This process, involving melt‐rock reactions and in situ crystallization, exhibits substantial spatial and temporal variability driven by melt volume and ascent velocity.

Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated

Water‐Depth‐Dependent 231Pa/230Th Responses in the Central North Atlantic Since the Last Glacial Maximum

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Atlantic Meridional Overturning Circulation (AMOC) plays an important role in regulating Earth's climate through inter‐hemispheric heat transport and has undergone substantial variations during past climate transitions. Sedimentary 231Pa/230Th is widely used to reconstruct AMOC strength, yet its application is complicated by its ...

In Search of the Lost Brown Trout (Salmo trutta Complex) Using DNA of Ancient and Modern Samples From the Southern Italian Peninsula

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT The current diversity and distribution of species and populations have been shaped by the major climatic oscillations during the Quaternary. The brown trout (Salmo trutta) is a striking example of the strong effect of past climate changes on the evolutionary history of species, in fact, the alternation of glacial/interglacial cycles has led to

Altitude‐Associated Divergence of the Gut Microbiome in Endangered Forest Musk Deer: Evidence From Integrated Metagenomics, Metabolomics, and Culturomics

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT High‐altitude environments expose mammals and their gut symbionts to multifaceted stressors—hypoxia, cold, and intense UV radiation. Whether gut microbial communities undergo compositional restructuring in response to these stressors, and whether such restructuring carries translational value for captive conservation, remain unresolved ...
