Spectral Evidence for Recent/Ongoing Activity in Mercury’s Praxiteles Basin

The Planetary Science Journal
Mercury’s surface, as revealed by the MESSENGER probe, lacks distinctive absorption features in the visible–near-infrared spectral range, except for hollows that display a 630 nm feature ascribed to sulfides.

Imaging Spectroscopy: Earth and Planetary Remote Sensing with the PSI Tetracorder and Expert Systems from Rovers to EMIT and Beyond

The Planetary Science Journal
A system for rapid analysis of spectroscopy data with emphasis on planetary surfaces, both imaging and single-spectrum data, is described. The system, called Tetracorder, is commanded by an expert system developed by expert spectroscopists.

Reflectance spectra of Mesosiderites: Implications for asteroid 4 Vesta [PDF]

, 2007
Oxygen isotopic data argues that HEDs and mesosiderites may be from the same parent body. A spectral survey of mesosiderites was done to determine their spectral properties in the visible and near-infrared and compare to ...

Exploring Organic-mineral Evolution in Planetary Analogs: Insights from Hydrothermal Alteration of Aromatic Molecules and Mafic Minerals

The Planetary Science Journal
Organic-mineral interactions are crucial drivers of diversity in abiotic systems on planetary surfaces. Despite their significance, the evolution of these systems, particularly the role of organic molecules in newly formed minerals, remains underexplored.

Thermal history analysis of granitic rocks in an arc-trench system based on apatite fission-track thermochronology: A case study of the Northeast Japan Arc

Journal of Asian Earth Sciences: X, 2019
We applied apatite fission-track (AFT) thermochronometry to the Cretaceous-Paleogene granitic rocks across the southern part of the Northeast (NE) Japan Arc in order to elucidate the denudation history.

Olivine or Impact Melt: Nature of the "Orange" Material on Vesta from Dawn

, 2013
NASA's Dawn mission observed a great variety of colored terrains on asteroid (4) Vesta during its survey with the Framing Camera (FC). Here we present a detailed study of the orange material on Vesta, which was first observed in color ratio images ...

Lower crustal zircons reveal Neogene metamorphism beneaththe Pannonian Basin (Hungary)

Open Geosciences, 2015
Neogene alkaline intraplate volcanic depositsin the Pannonian Basin (Hungary) contain many lowercrustal granulite-facies xenoliths. U-Pb ages have been determinedfor zircons separated from a metasedimentaryxenolith, using LA-ICPMS and SHRIMP techniques ...
