First Known Use of GEOCHEMISTRY



noun    (Concise Encyclopedia)

Scientific discipline dealing with the relative abundance, distribution, and migration of the Earth's chemical elements and their isotopes. Historically, geochemistry was concerned primarily with defining elemental abundances in minerals and rocks. Modern geochemical research also includes study of the continual recycling of the Earth's constituent materials through geologic processes, the cyclic flow of individual elements (and their compounds) between living and nonliving systems, and certain areas of cosmology.
