New Terrestrial Native Iron Discovered on Earth's Surface

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Native iron is a major common mineral in lunar samples and meteorites but rarely occurs on Earth's surface, as its stability requires highly reducing conditions with very low oxygen fugacity. To date, native iron has mainly been found in basalts, ophiolites, and deep hydrothermal systems.

Magnetic properties of geraisites, the first tektite strewn field identified in Brazil

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1163-1178, July 2026.
Abstract Geraisites are a newly recognized class of tektite from Brazil. They occur as centimeter‐sized, elongated to subspherical bodies scattered across surface gravel and shallow subsurface layers within a ~90‐km‐long strewn field extending between the municipalities of São João do Paraíso and Curral de Dentro, near the border between the states of ...

Thermomagnetic analysis of meteorites, 3. C3 and C4 chondrites [PDF]

Earth and Planetary Science Letters, 1976
Thermomagnetic analysis on all of the C3 and C4 chondrites, conducted under conditions of controlled oxygen fugacity, indicates the presence of a thermally unstable component in at least 5 of the C3 chondrites which upon heating results in magnetite production. This unstable component is most likely troilite (FeS).

Fluid‐Induced Magnetic Enhancement in Sandstone Friction Experiments: Implications for Coseismic Fault Temperature Estimates

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.

Tailoring the Anomalous Nernst Effect of Co/Pt Multilayers Grown on Strained Flexible Substrates

Advanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
Strain engineering offers a powerful approach to enhance the Anomalous Nernst Effect in flexible Co/Pt multilayers. This study demonstrates a 30% thermoelectric improvement under mechanical strain, directly attributed to the modulation of intrinsic interfacial interactions.

Magnetic Fabric: A Geophysical Approach for Identifying China's Neolithic Rammed Earth

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Accurate identification of rammed‐earth remains is essential for understanding early social complexity in Neolithic China. However, scientific methods for identifying rammed‐earth materials in Chinese prehistoric archeology remain limited, and identification still rely largely on field observations.
