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-

Petrology and geochemistry of nakhlite MIL 03346: A new Martian meteorite from Antarctica [PDF]

, 2005
MIL 03346 is the first nakhlite in the US Antarctic collection. We have performed detailed mineralogical and bulk-geochemical investigations to compare petrogenesis of this Martian meteorite with other ...

First disk-resolved spectroscopy of (4) Vesta

, 2009
Vesta, the second largest Main Belt asteroid, will be the first to be explored in 2011 by NASA's Dawn mission. It is a dry, likely differentiated body with spectrum suggesting that is has been resurfaced by basaltic lava flows, not too different from the

Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration

Journal of Raman Spectroscopy, Volume 57, Issue 2, Page 227-238, February 2026.
This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...

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 ...

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

Journal of Raman Spectroscopy, Volume 57, Issue 2, Page 343-359, February 2026.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

First mineralogical maps of 4 Vesta [PDF]

, 2012
Before Dawn arrived at 4 Vesta only very low spatial resolution (~50 km) albedo and color maps were available from HST data. Also ground-based color and spectroscopic data were utilized as a first attempt to map Vesta’s mineralogical diversity [1-4]. The

Multi‐Method Geochronology and P‒T Modeling Unravels the Thermo‐Tectonic History of the Rudall Province, Western Australia

Tectonics, Volume 45, Issue 2, February 2026.
Abstract The Rudall Province (RP) is a Paleo‐Mesoproterozoic belt that records numerous overprinting tectono‐metamorphic events. Situated on the eastern edge of the West Australian Craton (WAC), the RP represents a key area for understanding the Proterozoic assembly and subsequent tectonic history of Western Australia.

Evolution of the Source Mineralogy and Lithospheric Controls on Magmatism During the Northeast Atlantic Continental Breakup

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract The mid‐Norwegian Margin, part of the North Atlantic Igneous Province (NAIP), is a well‐studied volcanic rifted margin formed during the breakup between Greenland and Eurasia ∼56 Ma, with the largest accumulation of magmatic material hosted by the Vøring Margin section.
