Identification of volatility-controlled refractory lithophile element fractionation on asteroidal and planetary scale

• Applicant: Professor Dr. Andreas Pack
• Subject Area: Mineralogy, Petrology and Geochemistry
• Term: from 2010 to 2014
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 147293768

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.
