Preferential low-pH dissolution of pyroxene in plagioclase–pyroxene mixtures: Implications for martian surface materials
Acid weathering of plagioclase–pyroxene mixtures has been investigated with an open system kinetic dissolution model. The modeling reveals that elevated plagioclase/pyroxene ratios observed in some low-albedo martian regions and atmospheric dust could be partially caused by preferential dissolution of pyroxenes at pHs below ∼3–4. Surface materials with smaller grain sizes, affected by lower pH ...
متن کاملThe Accuracy of Derived Plagioclase Compositions from Multi-component, Multi-phase Sand Mixtures: Implications for Determining Martian Plagioclase Compositions
Introduction. Plagioclase feldspar has been identified as the dominant mineral phase in the martian crust [1-2] through analysis of Mars Global Surveyor Thermal Emission Spectrometer (TES) data. Martian meteorites , samples of isolated terrain on Mars, contain plagioclase in abundances secondary only to pyroxene. Terrestrial basalts and andesites contain primary plagioclase that is calcic-inter...
متن کاملPetrologic insights from the spectra of the unbrecciated eucrites: Implications for Vesta and basaltic asteroids
We investigate the relationship between the petrology and visible–near infrared spectra of the unbrecciated eucrites and synthetic pyroxene–plagioclase mixtures to determine how spectra obtained by the Dawn mission could distinguish between several models that have been suggested for the petrogenesis of Vesta’s crust (e.g., partial melting and magma ocean). Here, we study the spectra of petrolo...
متن کاملCalibration of the Eu Oxybarometer for Nakhlites
Introduction: Martian meteorites have various characteristics, which are direct clues to understanding the petrogenesis of Mars rocks. The variation in oxidation state among the Martian meteorites must have important implications for redox conditions of the Martian crust/mantle and overall differentiation on Mars. Wadhwa [1] and Herd et al. [2] reported that Martian basalts were formed under a ...
متن کاملAsteroid Surface Mineralogy Using Hapke Mixing Models: the Spectral Effects of Coarse-grained Metal
Introduction: The spectral properties of asteroid surfaces are governed by the mineralogy, the physical state, the amount of impact-produced glass, and the degree of space weathering of the asteroid regolith. Hapke's theories [1,2] and the work of [3] were used to create a model that calculates the spectrum of an airless planetary surface for a given modal mineralogy and mineral chemistry, with...
