Solar Wind Sodium and Potassium Abundance Analysis in Genesis Diamond-on-Silicon and Silicon Bulk Solar Wind Collectors, and How Hydration Affects the Microtexture of Olivine Phase Transformation at 18 GPa

Abstract The present work covers two distinct microanalytical studies that address issues in planetary materials: (1) Genesis Na and K solar wind (SW) measurements, and (2) the effect of water on high-pressure olivine phase transformations.

NASA’s Genesis mission collected SW samples for terrestrial analysis to create a baseline of solar chemical abundances based on direct measurement of solar material. Traditionally, solar abundances are estimated using spectroscopic or meteoritic data. This study measured bulk SW Na and K in two different Genesis SW collector materials (diamond-like carbon (DlC) and silicon) for comparison with these other solar references. Novel techniques were developed for Genesis DlC analysis. Solar wind Na fluence measuremen... (more)
