“…Conversely, our method might bring the element abundances closer to the "true" composition of CI chondrites. For example, the value for Pt obtained here is lower than published values because data sets from Hintenberger et al (1973) and Crocket et al (1967) were omitted (refer to the Data Reduction and Filtering section, where possible systematic errors are discussed). Our suggested value for Pt is supported by recently published analyses of CI chondrites (e.g., Horan et al 2003) also yielding lower Pt abundances.…”

“…Such atypical values were assumed to be due to sample preparation and/or analytical errors. An increased number of aberrant element/Ir ratios within a data set led to the exclusion of the entire analysis (e.g., Crocket et al 1967;Hintenberger et al 1973). In such cases, the ratios as well as the reference are marked bold.…”

Abstract-Siderophile elements have been used to constrain projectile compositions in terrestrial and lunar impact melt rocks. To obtain a better knowledge of compositional differences between potential chondritic projectile types, meteorite analyses of the elements Ru, Rh, Pd, Os, Ir, Pt, Cr, Co, Ni, and Au were gathered into a database. The presented compilation comprises 806 analyses of 278 chondrites including new ICP-MS analyses of Allende and two ordinary chondrites. Each data set was evaluated by comparing element ratios of meteorites from the same chondrite group. Characteristic element abundances and ratios were determined for each group. Features observed in the element abundance patterns can be linked directly to the presence of certain components, such as the abundance of refractory elements Os, Ir, and Ru correlating with the occurrence of refractory inclusions in CV, CO, CK, and CM chondrites. The refined characteristic element ratios appear to be representative not only for meteorites, but also for related asteroidal bodies. Chondrite element ratios were compared to previously published values from impact melt rocks of the Popigai and Morokweng impact structures confirming that an identification of the specific type of projectile (L and LL chondrite, respectively) is possible. The assessment for Morokweng is supported by the recent discovery of an LL chondrite fragment in the impact melt rocks. Ultimately, the database provides valuable information for understanding processes in the solar nebula as they are recorded in chondrites. A new type of complementarity between element patterns of CK and EH chondrites is suggested to be the result of condensation, redox, and transportation processes in the solar nebula.

“…Additional information has been provided by Case and others (1973), Krahenbiihl and others (1973), Hintenberger, Jochum, and Seufert (1973), Herman and Wichtl (1974), Anders and others (1976), and Higuchi and others (1976). These additional figures are in good agreement with earlier determinations, except for the data of Hintenberger, Jochum, and Seufert (1973), which tend to be considerably higher than other measurements on the same meteorites; the discrepancy may lie in the technique used, since Hintenberger and coworkers utilized spark-source mass spectrometry, whereas all other determinations were made by neutron-activation analysis. The results are summarized in table 71.…”

The chemical composition of the newly observed fallen chondrites Parambù, 1967, and Marilia, 1971, was determined. Wet chemical methods were used for major elements analyses and the abundances of heavy trace elements from tungsten to uranium were determined by spark source mass spectrometry. The chemical composition confirmed the classification of Marilia as an H‐group chondrite by Avanzo et al. (1973): Parambù was classified as an LL‐group chondrite.
