Due to the estimate nature of these values, no single recommendations are given. All values are normalized for these tables. Underlined zeroes indicate figures of indeterminable significance that were present in the source notation.

Estimated abundance of the elements in the continental crust (C1) and in seawater near the surface (W1). The median values of reported measurements are given. Concentrations of the less abundant elements may vary with location by several orders of magnitude.

Accuracy of the solar abundances varies between ± 10% and a factor of two, values more uncertain than that are marked with "about". The solar system abundances are mainly derived from carbonaceous chondrite meteorites and are assumed generally accurate to ± 10% or better. Solar system abundances based on other sources are marked with asterisks (*).
