Quantitative Mineralogy of Planetary Silicate Ternary Mixtures Using Raman Spectroscopy

open access: yesEarth and Space Science, 2023
A 532‐nm‐excited lunar Raman spectrometer (LRS) has been selected as a scientific payload of the Chang'e‐7 mission, exploring mineralogy assemblages in the lunar south polar region.

ON THE EVOLUTION OF DUST MINERALOGY, FROM PROTOPLANETARY DISKS TO PLANETARY SYSTEMS [PDF]

open access: yesThe Astrophysical Journal, 2011
Mineralogical studies of silicate features emitted by dust grains in protoplanetary disks and Solar System bodies can shed light on the progress of planet formation. The significant fraction of crystalline material in comets, chondritic meteorites and interplanetary dust particles indicates a modification of the almost completely amorphous ISM dust ...

Time-resolved Raman spectroscopy for in situ planetary mineralogy [PDF]

open access: yesApplied Optics, 2010
Planetary mineralogy can be revealed through a variety of remote sensing and in situ investigations that precede any plans for eventual sample return. We briefly review those techniques and focus on the capabilities for on-surface in situ examination of Mars, Venus, the Moon, asteroids, and other bodies.

Characterization of ferric hydroxysulfate on Mars and implications of the geochemical environment supporting its formation [PDF]

open access: yesNature Communications
Sulfate minerals are significant components of the martian surface and provide clues about the martian geochemical environment. One unusual Fe-sulfate phase has been intriguing Mars scientists for over a decade due to its unique spectral bands that are ...

A Spectroscopic Study of Mars-analog Materials with Amorphous Sulfate and Chloride Phases: Implications for Detecting Amorphous Materials on the Martian Surface

open access: yesThe Planetary Science Journal, 2023
The Chemistry and Mineralogy X-ray diffraction (XRD) instrument aboard the Curiosity rover consistently identifies amorphous material at Gale Crater, which is compositionally variable, but often includes elevated sulfur and iron, suggesting that ...

(U–Th)/He thermochronometric mapping across the northeast Japan Arc: towards understanding mountain building in an island-arc setting

open access: yesEarth, Planets and Space, 2020
Topographic relief in arc-trench systems is thought to be formed by plate subduction; however, few quantitative investigations have so far been reported, with respect to the related mountain building process.

Plausible Constraints on the Range of Bulk Terrestrial Exoplanet Compositions in the Solar Neighborhood

open access: yesThe Astrophysical Journal, 2023
Rocky planet compositions regulate planetary evolution by affecting core sizes, mantle properties, and melting behaviors. Yet, quantitative treatments of this aspect of exoplanet studies remain generally underexplored.

Th e age of detrital zircon from metasedimentary rocks of the Ternuvate strata (West Azov block of the Ukrainian Shield)

open access: yesДоповiдi Нацiональної академiї наук України, 2023
The Ternuvate strata comprise metamorphic rocks that make up the Haichur arcuate structure, which is about 72 km long. Its western part lies within the Andriivka fault zone, which separates the Vovcha and Huliaipole blocks, while the eastern part is ...

Salt Distribution from Freezing Intrusions in Ice Shells on Ocean Worlds: Application to Europa

open access: yesThe Planetary Science Journal, 2023
Several icy moons and dwarf planets appear to have hosted subsurface liquid water. Liquid water intruding upwards into the icy outer shells of these worlds freezes, forming ice and (from ocean solutes) non-ice solids.
