Scientific paper

It is pointed out that chondritic meteorites comprise over 85% of meteorite falls. About 5% of these, some 33 falls, belong to a set of collectively known as carbonaceous chondrites. They are among the most primitive materials in the solar system. Taxonomic parameters are considered, taking into account petrography, refractory and volatile abundances, and oxygen isotope systematics. A table lists 20 carbonaceous chondrite samples which have been studied. After instrumental neutron activation analysis, the samples were prepared for radiochemical neutron activation analysis. Elemental concentration data determined for the samples are listed in a second table. A third table lists the mean elemental concentrations for each group along with relative standard deviations and 95% confidence limits on the mean.
