Models of earth structure inferred from neodymium and strontium isotopic abundances.
A simplified model of earth structure based on the Nd and Sr isotopic characteristics of oceanic and continental tholeiitic flood basalts is presented, taking into account the motion of crustal plates and a chemical balance for trace elements. The resulting structure that is inferred consists of a lower mantle that is still essentially undifferentiated, overlain by an upper mantle that is the r...
متن کاملCalcium isotopic ratios and rare earth element abundances in refractory inclusions from the Allende CV3 chondrite
Refractory inclusions in primitive meteorites are the oldest objects formed in the Solar System. They exhibit large massdependent isotopic effects in many elements, including Si, Mg and Ca, indicative of their complex origin. We report data for both mass-dependent (d) and mass-independent (e) Ca isotopic effects, and rare earth element (REE) abundances in six refractory inclusions from the Alle...
متن کاملChondrite barium, neodymium, and samarium isotopic heterogeneity and early Earth differentiation.
Isotopic variability in barium, neodymium, and samarium in carbonaceous chondrites reflects the distinct stellar nucleosynthetic contributions to the early solar system. We used 148Nd/144Nd to correct for the observed s-process deficiency, which produced a chondrite 146Sm-142Nd isochron consistent with previous estimates of the initial solar system abundance of 146Sm and a 142Nd/144Nd at averag...
متن کاملNeodymium and strontium isotopic study of Australasian tektites: New constraints on the provenance and age of target materials
Nd and Sr isotopic studies of Australasian tektites provide info~ation on the age and provenance of the target materials and allow us to characterize the target area and the impact process leading to tektite formation. ENd values of australites, splash-form indochinites, and Muong Nong-type indochinites are indistinguishable within analytical uncertainty and average -11.5 cu. Depleted mantle Nd...
متن کاملGCR Neon Isotopic Abundances: Comparison with Wolf-Rayet Star Models and Meteoritic Abundances
Measurements of the neon isotopic abundances from the ACE-CRIS experiment are presented. These abundances have been obtained in seven energy intervals over the energy range of ~80<E<280 MeV/nucleon. The Ne/Ne source ratio is derived using the measured Ne/Ne abundance as a "tracer" of secondary production of the neon isotopes. We find that the Ne/Ne abundance ratio at the cosmic-ray source is a ...
