متن کاملSolar Noble Gases in Enstatite Chondrites and Implications for the Formation of the Terrestrial Planets
Introduction: In a companion abstract [1], we report evidence for tiny amounts of most likely primordial noble gases with solar-like elemental and isotopic composition admixed to Q-type primordial noble gases in an E chondrite. Here, we discuss possible implications of this finding for terrestrial planet formation. The genetic relation of the noble gases in planetary bodies to those in the Sun,...
متن کاملFormation of Sulfates on Parent Bodies of Carbonaceous Chondrites, Ceres,
Introduction: Chemical compounds of S 6+ , sulfates and/or SO3, occur on Earth, Venus, Mars, parent bodies of carbonaceous chondrites, and icy surfaces of Europa and Ganymede. On the terrestrial planets, formation of S 6+ species is related to atmospheric photochemical processes that produce O2 and other O-rich oxidants. Here we explain the formation of sulfates within chondritic bodies through...

متن کاملAqueous Oxidation of Parent Bodies of Carbonaceous Chondrites and Galilean Satellites Driven by Hydrogen
Figure 1. Stability fields of sulfate and bisulfide at a total pressure of 100 bar. The thin solid curves represent equal activities of SO4 and HS at various pH. The QFM curve represents equilibrium (2) and HM stands for hematitemagnetite buffer. Sulfate is stable at higher temperature and lower ƒH2. Low-temperature formation of sulfate in asteroidal environments requires complete oxidation of ...
