M.; Grossman, L.; Mayeda, T. K.; Molini-Velsko, C.; Allen, J. M.; El Goresy, A. Abstract: Two forsterite-, fassaite-, spinel-rich inclusions in Allende which share common mineralogy and texture with three previously described inclusions are described. These inclusions were at least partially molten at ... NASA Center: NASA (non Center Specific) Publication Year: 1984 Added to NTRS: 2004-11-03 Accession Number: 84A32467; Document ID: 19840049680 Petrographic studies of refractory inclusions from the Murchison meteorite Author(s): Macpherson, G. J.; Grossman, L.; Hashimoto, A.; Bar-Matthews, M.; Tanaka, T. Abstract: Textural and mineral-chemical data on freeze-thaw disaggregated refractory inclusions from the Murchison meteorite are reported. The data were obtained with neutron activation analysis, SEM, and spectroscopy, the study ...

J.; Grossman, L. Abstract: Inclusions called 'fluffy' Type A's or FTA's in the Allende meteorite are examined as possible candidates for relict vapor-solid condensate grains, remaining from the original solar nebula. Type A inclusions are ... NASA Center: NASA (non Center Specific) Publication Year: 1984 Added to NTRS: 2004-11-03 Accession Number: 84A22371; Document ID: 19840039584 The origin and significance of reverse zoning in melilite from Allende Type B inclusions Author(s): Macpherson, G. J.; Paque, J. M.; Stolper, E.; Grossman, L. Abstract: Many of Type B Allende inclusions are found to have reverse zoning over restricted portions of each crystal, in contrast to those in Type A's, which are reversely zoned throughout. Results of dynamic crystallization ...

J.; Hashimoto, A.; Grossman, L. Abstract: The origin and composition of the rim sequence on the refractory inclusion in the Allende meteorite are studied. The different textures, mineralogy, and mineral-chemistry of the four layers of the rim are described. The ...
