Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 2048-2072, August 2026.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

Potassium isotopic compositions and exposure ages of evolved and silica‐rich achondrites

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 2140-2162, August 2026.
Abstract Some of the oldest igneous rocks in the Solar System include evolved and silica‐rich achondrites that originate from parent bodies less than 1000 km in diameter, referred to as planetesimals. While Earth was initially in a molten state and required continental crust formation and plate tectonics to generate andesite bulk compositions, evolved ...

Impact provenance and age of a unique basalt found in Apollo 12 regolith

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 2073-2085, August 2026.
Abstract Basaltic sample 12032,366‐18 from the Apollo 12 landing site is distinct among basalts collected at this site, other Apollo landing sites, and lunar meteorites in terms of its age, bulk rock composition, and isotopic composition. We present new Pb isotopic data obtained by in situ Secondary Ion Mass Spectrometry on multiple mineral phases in ...

Ductile Extrusion Triggered by Continental Collision in NE Brazil

open access: yesTerra Nova, Volume 38, Issue 4, Page 266-277, August 2026.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.
