| Abstract | Introduction: We have completed SEM, EMP, and SIMS analyses on phases from martian meteorite ALH77005 (ALH) in order to determine why the olivine mineral fractions do not lie on the Sm-Nd isochron defined by the other phases (Fig. 1). Two possible explanations for the olivine mineral fractions lying off the isochron are: 1) the olivines are xenocrystic and would therefore be out of isotopic equilibrium with the rest of the rock, or 2) an unradiogenic Nd component was added to the olivine mineral fractions by alteration or shock processes. |
