A variety of mass spectrometric analyses of undifferentiated                    meteorites will be conducted to study the conditions,                           processes and timescales involved in the early history of the                   solar system and in the formation of planetary bodies.  The                     samples will be both whole rock and seperated phases, notably                   phosphates.  The analyses will include coordinated                              application of both noble gas and thermal emission mass                         spectrometry.  The research is organized into three related                     projects: 1) An attempt will be made to determine the cosmic                    abundance of Pu-244 based on analysis of fission Xe in                          undifferentiated meteorites, 2) Rb, Sr, and Sr-87/Sr-86 in                      low Rb/Sr phases of chondrites will be determined in order                      identify initial Sr-87/Sr-86 ratios and constrain the                           duration of 'metamorphism' for these meteorites, 3) Noble gas                   abundances in chondrites will be measured using isotope                         dilution rather than the conventional peak-height comparison                    technique.  This should give an order-of-magnitude                              improvement in accuracy.  The PIs will collaborate in these                     analyses with Lugmair at Scripps, Burnett at Cal Tech, and                      Pellas at Paris.
