Abundance in carbonaceous meteorites (by weight)

The values here are estimates adapted from references 1 and 2 by taking a consensus or averaging where appropriate. For ease of comparison with other abundance values, all abundance data in WebElements have been scaled to parts per billion (ppb), both as ppb by weight and by number of atoms. Values for less common elements should be treated with some caution and none of the data is better than one or sometimes two significant figures. Values for any individual carbonaceous meteorite will vary widely. Values for other classes of meteorite will vary from those given here.

Units

ppb

Notes

The units used in WebElements for all abundance data are ppb by weight which means parts per billion by weight, that is mg tonne-3 or mg per 1000 kg. All abundance data are also presented as ppb by atoms, which means atoms of the element per billion atoms.

The reason for rescaling all data is as follows. It is common to see, say, solar abundances expressed as the number of atoms of the element relative to a scale upon which the abundance of hydrogen is defined as 1012. This makes comparison with, say, crustal abundances difficult, since crustal abundances are often expressed in terms of parts per million by weight. Hence a common scale is used throughout and I chose ppb as this gives manageable numbers for most elements.
