Solar 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 کاملNoble Gases in Terrestrial Diamonds: Preliminary Results
Motivated by exciting, but puzzling, noble gas results in terrestrial diamonds (e.g. high He/He ratios close to the solar value from industrial class diamonds [Ozima et al., 1983] and low 40ArPAr [ = 189] from an Arkansas, U.S.A., diamond [Melton and Giardini, 1980]), we undertook the study of noble gases in diamonds from different locations. Although this is ongoing research, we can report pre...

متن کاملNoble gases in mantle plumes.
Trieloff et al. (1) provided neon isotope data to argue that mantle neon originates as a trapped component in meteorites rather than having a pristine solar composition. That finding, if true, has important consequences for understanding the mechanism of volatile input into the mantle, because it rules out models involving direct incorporation of solar gases. The main argument that Trieloff et ...
متن کاملNoble Gases in Tagish Lake
Introduction: Tagish Lake has been classified as a CI2 chondrite [1] with an interstellar grain abundance enhanced over that of CI1 and CM2 chondrites [2]. Noble gases have been used as markers for the presence of exotic, presolar grains in chondritic meteorites: Xe-HL (nanodiamonds) and Xe-s/Ne-E (SiC). We have measured He, Ne, Ar and Xe in whole-rock Tagish Lake, and an orthophosphoric acidre...
