英文摘要
Using advanced analytical techniques, we will determine the relative abundances of refractory lithophile elements in bulk chondrites and selected terrestrial materials. The goal is the identification of volatility-controlled fractionation of refractory lithophile elements on asteroidal and planetary scale. The results will have important implications on understanding of the origin of refractory lithophile element fractionation, e.g., Nb/Ta or Sm/Nd between terrestrial planets and chondrites.
