Corundum Discovered by SuperCam and the Perseverance Rover at Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase‐rich light‐toned float rocks.

Spectral Reflectance Properties (0.3–2.5 μm) of Mesosiderites and Pyroxene+Metal Mixtures

The Astrophysical Journal Supplement Series
To date, the parent body of mesosiderites remains uncertain. Some candidate bodies have been proposed, including 4 Vesta and 16 Psyche. In this study, we performed a comprehensive spectroscopic survey of mesosiderites and pyroxene+metal mixtures to ...

Seismic Exploration for Magmatic Brine Lenses: An Example From Soufrière Hills Volcano, Montserrat

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The majority of metallic ore deposits are related to processes associated with ancient or modern volcanic systems. Beyond geothermal energy production, volcanoes also represent a potential resource of critical metals, including those required for carbon‐neutral technologies. Geothermal metals occur in subsurface fluid reservoirs fed by surface

Impact-induced mixing generated the stratified soils of the Lunar South Pole Aitken Basin

Communications Earth & Environment
The Mg-pyroxene annulus in the South Pole–Aitken (SPA) basin holds crucial information about the lunar crustal evolution, yet its mineralogy and origin remain debate. Here we analyzed the mineralogy, exogenic ejecta, and soil evolution of the 2.8-billion-

INTERRELATIONS BETWEEN MINERAL BODIES IN FENITE HALO OF THE WESTERN CONTACT OF THE ILMENOGORSKY MIASKITE COMPLEX [PDF]

Минералогия, 2017
The northwestern contact of the Ilmenogorsky miaskite complex exhibits a succession of rocks from early banded meso- and melanocratic syenites to granosyenites and granites and further complex series of leucocratic syenites, carbonatites, syenitic and ...

Thermodynamic Controls on the Competition Between CO2 Solute Transport and Retention in Fracture‐Pore Media: Insights From Real‐Basalt Microfluidics

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Reactive‐surface exposure during basalt carbonation is controlled by the entry and retention of fracture‐transported CO2 solute within adjacent pores, yet these pore‐scale processes remain poorly constrained under reservoir temperature and pressure.

Petrology of the 1952 Eruption and Ancient Lava and Pyroclastic Flows of Krenitsyn Peak Volcano, Onekotan Island, Kuril Arc, Russia

Geosciences
Krenitsyn Peak is one of the two active volcanoes on Onekotan Island (Greater Kuril Ridge). The inaccessibility of the island, along with the volcano being situated within a sizeable (7 km in diameter) and cold (3.7 °C) caldera lake, has led to minimal ...
