Phase Development in Carbothermal Reduction and Nitridation of Ilmenite Concentrates
htmp, 2012 Abstract The phase development in the course of carbothermal reduction and nitridation of ilmentie concentrates and synthetic rutile was studied in temperature programmed reduction (623–1873 K) and isothermal reduction experiments.

Meteoritics &Planetary Science, EarlyView.Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Stardust Mine: A 2024 gabbroic shergottite from Arizona, USA
Meteoritics &Planetary Science, EarlyView.Abstract This study provides an initial characterization of Stardust Mine, a fresh gabbroic enriched shergottite collected in Arizona, USA, in September 2024 and is the first Martian meteorite to be unequivocably collected on US soil. Analysis was conducted on the type specimen and finds that Stardust Mine is composed of equal proportions of pyroxene ...

Mineralogy, mineral chemistry, and redox equilibria in ten aggregate particles from asteroid Bennu
Meteoritics &Planetary Science, EarlyView.Abstract Examination of 10 Bennu aggregate particles has revealed the presence of many phases which taken together can provide constraints on the oxygen fugacity (fO2) of Bennu samples. Phyllosilicates (saponite and serpentine), carbonates, oxides (magnetite, chromite), sulfides (pyrrhotite, pentlandite), phosphate (hydroxyapatite, Na‐Mg‐phosphate ...

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT
Meteoritics &Planetary Science, EarlyView.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 ...

Experimental study on the chemical and geo-chemical properties of a Fe3O4 dominated ore
Chemical Engineering Transactions, 2018 Dressing iron from the primary ores is the hot topic all the way. In our study, one primary magnetite iron ore was selected to analyze the chemical composition properties, and micro-sturctures of the mineerals. The results show that magnetite is the main

Impact provenance and age of a unique basalt found in Apollo 12 regolith
Meteoritics &Planetary Science, EarlyView.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 ...
