It also reveals a composition of the rock based on elemental abundance.

Different studies generally find varying values for elemental abundances.

Values are subject to various geological assumptions but assumed acceptable as an indication of elemental abundance in crustal rocks (C3).

Thereafter, nucleosynthesis produced the elemental abundance of the early universe.

Various estimates of elemental abundances have been published and these often disagree to some extent.

Although the baryon per photon ratio is important in determining elemental abundances, the precise value makes little difference to the overall picture.

This concentration is enough to make erbium about 45th in elemental abundance in the Earth's crust.

Loose correlations have been observed between estimated elemental abundances in the universe and the nuclear binding energy curve.

An estimate of the elemental abundances in the total mass of the Earth.

By convention, such heavier elements produced in normal elemental abundance, are not referred to as "nucleogenic."
