Nuclear binding energies and abundances of isotopes in the Earth's crust or MORB - Correlation?

The binding energy of an atom is a measure of the energy needed to hold the parts of its nucleus together. See the attached file BindingEnergies.pdf for an idea of how the binding energies of various isotopes vary with their mass and composition.

In general, the highest binding energies are found in some of the isotopes of iron (Fe). Atoms of elements more massive than iron can be the source of energy through nuclear fission, where they break down into smaller parts (lighter isotopes). Atoms lighter than iron can yield energy through fusion, where an isotope is increased in mass.

This zomb seeks to find out whether there are any correlations between the binding energies of isotopes and their abundance in the Earth's crust or in MORB, a uniform variety of basalt produced at Mid-Ocean Ridges (and possibly representative of the Upper Mantle).

Values for the relative abundances of different elements in the Crust can be found from geochemical sources. These values are often represented as silicates, and may need conversion to represent the significant elements or isotopes.

Note that different isotopes of the same element may have very different binding energies. Multiple bids are invited for this zomb, ranging from low bids for simple analyses, to higher ones for more detailed work.

The range of elements considered may also vary, from representational atoms to a fuller range. Hydrogen and other gaseous elements should be excluded. (ZBL#153)
