Project -- Earth Science Data Compilations -- Compendium of Geochemistry
The book focuses on compositional data and related references for such substances as solar photosphere, meteorites, igneous rocks, soils, sedimentary rocks, surficial waters, marine and terrestrial organisms (including humans), and aerosols. It emphasizes the use of original raw data as much as possible, and applies the statistical technique of factor analysis to elucidate any underlying interrelationships among chemical elements and given sample sets. Whenever applicable, simple chemical thermodynamic models are introduced to explain the observed partitioning of elements among different phases.
