Summary:
These are the papers of Brian Harold Mason, Curator Emeritus, Meteorites Division, Department of Mineral Sciences, National Museum of Natural History. Mason curates and classifies the 700+ meteorites recovered each year from Antarctica under a joint Smithsonian-National Aeronautics and Space Administration (NASA)-National Science Foundation program. His research focuses on the mineralogy and petrology of meteorites and cosmochemistry. Materials include correspondence, memoranda, and project files pertaining to the Allende Meteorite, Antarctic meteorites, and a biography of Victor Moritz Goldschmidt.

Inclusions in the Allende Meteorite / Brian Mason and S.R. Taylor

Physical description:

Date:

Summary:
Six discrete groups of inclusions have been distinguished in the Allende meteorite. Groups I, V, and VI are mostly melilite-rich chondrules, although some have been extensively altered to fine-grained aggregates; Groups II and III are mostly fine-grained aggregates made up largely of spinel and fassaite; Group IV are olivine-rich aggregates and chondrules. Each group has a distinctive trace-element pattern, most clearly shown by the rare-earth (RE) distribution pattern. Group I has an unfractionated pattern (except for a small positive Eu anomaly) at about 10-15 times chondrites; Group II has a highly fractionated pattern with depletion of the heavier lanthanides (Gd-Er) and negative Eu and positive Tm and Yb anomalies; Group III has an unfractionated pattern at about 20 times chondrites, except for negative Eu and Yb anomalies; Group IV has a relatively unfractionated pattern at 2-4 times chondrites; Group V has an unfractionated pattern at 10-20 times chondrites; Group VI has an unfractionated pattern at 10-20 times chondrites, except for positive Eu and Yb anomalies (i.e., complementary to Group III). The complex patterns of trace element distribution in these Allende inclusions indicate a complex history of formation of this meteorite from the solar nebula.
