The geochemical table of the elements for 1959 (with French, German, Russian and Spanish keys), cast in the framework of the conventional periodic table, contains the following data for each element:
Weight and structure: atomic number, atomic weight, weight of 1 atom, and electronic-shell structure.
Size and charge: atomic, ionic, and miscellaneous radii, atomic and ionic volumes, lattice-energy coefficients, ionization potentials, and radius ratios. Ionic radii are adjusted for various co-ordinations of each ion.
Isotopic: naturally occurring isotopes with per cent abundance, half lives, and type of radiation decay.
Nuclear: thermal neutron-capture cross section and nuclear spin in multiples of h/2π.
Thermodynamic: standard heat of formation (gas), standard free energy of formation (gas), logarithm of equilibrium constant (gas), and entropy at 25°C. (gas and solid).
Mineralogic: common or geochemically significant minerals with per cent element contained.
Value: range of cost in United States dollars per unit weight or volume of reagent-pure element.
Abundances in grams per metric ton (printed in green overprint): abundances in sedimentary, metamorphic, igneous, and miscellaneous rock types (34 possible categories), in sea water (with transfer percentage), in iron, sulfide, and silicate meteorite phases), and in the universe (including volatiles) are tabulated. Where possible, number of individual analyses and standard deviations for the arithmetic average are given as superscripts and subscripts respectively. Boldface indicates a general or global average; averages in lightface are local or specific with respect to area and/or time.
Series of geochemical interest: electromotive, oxidation-reduction, electrochemical equivalents, entropy of ions in aqueous solution, cation-field strength, ionic replacement, electronegativity, reaction, zoning, affinity for sulfur in melt, solubility of sulfides, exchangeability in clays, and hydroxide precipitation pH's. Ionic potential and co-ordination data are graphed.
A post-1953 bibliography of nonradiogenic isotope abundance data and a listing of abundances of elements in soils and igneous rocks, not included in the table, are included in the text.
