Table 1 in The Dunbogan L 6 Chondrite: A New Meteorite Fall from New South Wales, Australia

Table 1. Mineral chemistry of phases in the Dunbogan L6 chondrite.Analyses by P. Garlick and P.Ashley, University of New England, using a JEOL JSM5800LV SEM/Oxford Link Isis EDS, at 20kV and 34 nA, with a 100 second count time; n.d. = not detected; *In chromite, Fe 2 O 3 and FeO are calculated assuming stoichiometry. In other analyses total Fe is expressed as FeO.
