Multi‐Stage Evolution of Subducted Oceanic Mantle: The Marlborough Ultramafic Suite (New England Orogen, Australia)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Oceanic lithosphere is continuously destroyed by subduction, challenging our ability to develop tectonic reconstructions. One way to tackle this problem is to examine relics of once‐consumed oceanic domains preserved along convergent margins. In the New England Orogen (eastern Australia), disrupted exposures of ultramafic rocks loosely define ...

Influence of Thermal Treatment on the Sorption Properties of Some Latvian Clays

Hidromica containing Latvian Devonian and Quaternary clays are investigated. Both clays contain without hidromica also kaolinite. Devonian clay of deposit Liepa is lime less clay and contains sandy fraction about 22 %.

Investigating Layered Cratonic Lithosphere in the Fennoscandian Shield

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Cold, thick, and chemically depleted lithosphere with high seismic velocity and low attenuation characterizes continental cratons. However, discrepancies between xenolith‐based thermal constraints and those inferred from surface‐wave seismic models, together with the widespread observation of mid‐lithosphere discontinuities, challenge the ...

Linking Tectonics and Cratonic Vertical Motions: Deep‐Time Thermochronology Reveals >1,000 Myr of Low‐Temperature Conditions in Southeastern Finland

Tectonics, Volume 45, Issue 9, September 2026.
Abstract The Fennoscandian Shield potentially hosts the longest continuous habitable conditions for Earth's deep biosphere. Billion‐year equilibrium freeboard conditions of cratons and the longevity of deep biosphere microbial communities are directly related through the thermal histories of rocks that host these communities.

Evaluating Forced Versus Plume‐Induced Subduction Initiation for the Talkeetna‐Bonanza Arc System: Implications for Permo‐Triassic Paleogeography of the North American Cordillera

Tectonics, Volume 45, Issue 9, September 2026.
Abstract The mechanisms by which new subduction zones form remain highly debated. Here we use Permo‐Triassic strata to evaluate potential mechanisms for initiation of the Talkeetna‐Bonanza Arc of the northern North American Cordillera. New mapping and analysis of Permian and Upper Triassic strata on the Alaska Peninsula suggest a period of uplift ...

Dovetailing the Genetic, Developmental and Functional Bases of the Adaptation of Stomatal Traits to Climate

Ecology Letters, Volume 29, Issue 9, September 2026.
For diverse ecotypes of Arabidopsis thaliana grown in a common garden, we tested a three‐tier approach to clarifying the drivers of gmax. Our analyses yielded novel findings for this wide‐ranging species: a larger gmax was achieved through greater epidermal allocation to stomata, via a higher stomatal index and smaller epidermal pavement cells; larger ...
