Introduction to geochemistry and its applications. Tome 1. Concepts and methods. Chemical zonation of the Earth

This first tome of the introduction to geochemistry and its applications is divided into 9 chapters dealing with: the chemical elements and the emergence of concepts in the development of human thought and scientific research; the abundance and distribution laws of chemical elements and of their isotopes; the geochemistry of trace elements and the modeling of magmas differentiation; isotopes, isotopic effects and the basis of radio-geochemistry; isotopic geochemistry of today's oceanic volcanism and the identification of the main mantle source domains; the Precambrian basic and ultra-basic magmatism; the continental crust and its evolution; the geochemistry of Archean granitoids and of the primitive crust; and the statement and evolution of the big terrestrial reservoirs.
