Isheyevo Meteorite: Genetic link between CH and CB chondrites? [PDF]

, 2006
Based on the mineralogy, petrography, bulk chemical, oxygen, and nintrogen isotopic compositions and 40Ar-39Ar age, Isheyevo is genetically related to CH and CB carbonaceous chondrites and provides a link between these group of pristine ...

Infrared spectroscopy of circumstellar dust: signs of differentiated materials? [PDF]

, 2006
Mid-infrared absorption spectra of powdered achondrites are compared with the astronomical spectra of dust around young, evolving stars, to find evidence (or not) of dust formed in collisional cascades of material from ...

Investigating the Compositional Heterogeneity of Pure, Crystalline Plagioclase Exposures within the Moon’s Anorthositic Crust Using Moon Mineralogy Mapper and Diviner Data

The Planetary Science Journal
Questions about the formation of the primary anorthositic crust of the Moon remain unanswered. Spectroscopic surveys of the lunar crust have evidenced the presence of pure, crystalline plagioclase exposures (PCPEs) across the surface, which are assumed ...

Reflectance spectroscopy in planetary science: Review and strategy for the future [PDF]

Reflectance spectroscopy is a remote sensing technique used to study the surfaces and atmospheres of solar system bodies. It provides first-order information on the presence and amounts of certain ions, molecules, and minerals on a surface or in an ...

Petrogenesis of lunar rocks: Rb-Sr constraints and lack of H2O [PDF]

Rb and Sr isotopic data and other chemical data indicate major lunar differentiation at about 4.6 AE and very limited subsequent differentiation. The constraints of limited differentiation post 4.6 AE and the apparent lack of H2O on the moon, when ...
