Fossilised Pioneer Microbialite Communities on Basaltic Substrates at Lake Ashenge (Tigray, Ethiopia): A Model for Ecosystems in Noachian–Hesperian Martian Lakes?

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Microbial communities are strongly controlled by local nutrient availability, frequently resulting from mineral weathering and erosion. On Earth, basaltic rocks in habitable alkaline lacustrine environments are often initially colonised by ‘pioneer’ communities that induce the precipitation of fine‐scale microbial carbonate ‘coatings’; on Mars,

Coupled Effects of Grain Size and Metallic Iron on Spectral and Polarimetric Properties of Lunar Simulants

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The lunar surface is heterogeneous in grain size and metallic iron abundance due to diverse histories of space weathering. The spectral and polarimetric properties of the lunar regolith are strongly affected by both grain size and metallic iron particles.

Catalytic activity of Co-åkermanite and Co-pyroxene in oxidation reactions

, 2011
Two calcium–cobalt silicates were synthesized in which cobalt occupies different structural positions. The crystal phases belong to two main structural silicate types.

Ancient Impact Melt Near the Lunar South Pole: Distribution, Provenance, and Sampling Strategy

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Due to a lack of pre‐Nectarian samples associated with specific impacts in the Apollo suite, the early Solar System's impact chronology is poorly constrained. We investigate where Artemis and other south polar lunar missions could sample impactites to determine the ages of pre‐Nectarian craters, focusing on the ancient craters Haworth ...

On "Bidalotite", a new orthorhombic pyroxene derived from cordierite

, 1937
The paper gives an account of a new type of orthorhombic pyroxene recently discovered in the biotite-cordierite-hypersthene granulites occurring near the village Bidaloti in Mysore.

Quantitative Evaluation of Shock Metamorphism in Clinopyroxene Using In Situ X‐Ray Diffraction Measurement of Lattice Strain

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Shock metamorphism is a ubiquitous process in our solar system. Shock pressure can be related to the lattice strain (ε) of individual minerals within a shocked sample. The lattice strain can be quantified within intact samples by in situ micro‐X‐ray diffraction (μXRD) using the Williamson‐Hall method. The Williamson‐Hall lattice strain (W‐H ε)

Waste Loading and Durability of Calcium Aluminosilicate Glasses for Immobilization of Plutonium‐Contaminated Material

International Journal of Applied Glass Science, Volume 17, Issue 4, October 2026.
ABSTRACT Calcium aluminosilicate (CAS) glass was assessed for its ability to immobilize elements present in Plutonium‐Contaminated Materials (PCM) including metals (Fe and Cr), polyvinyl chloride (PVC), and Pu (investigated using the nonradioactive surrogates Ce and Hf).

Revisiting olivine‐phyric shergottites: Pyroxene crystallization pressure and the role of undercooling

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2466-2475, October 2026.
Abstract Shergottites are the most abundant meteorites from Mars and a major source of information on magma reservoirs, transport, and eruption, particularly in the late Hesperian northern hemisphere. Conflicting interpretations have arisen on the crystallization conditions of pyroxene in olivine‐phyric shergottites.

High‐pressure phase preservation in ordinary L‐chondrite melt veins: Evidence for control by post‐shock thermal evolution

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2549-2566, October 2026.
Abstract This study investigates the petrography and mineralogy of three L‐type ordinary chondrite meteorites: Northwest Africa (NWA) 4137 (L6), Homestead (L5), and Kunashak (L6). We studied the shock‐related deformation features in the matrix and the characteristics of the melt veins, including the presence or absence of high‐pressure (HP) phases. Our
