This unique guide covers a broad range of topics on the distribution and abundance of elements and isotopes in geologic systems as a result of chemical and isotopic reactions. Chapters develop relevant geochemical principles in a logical sequence and with an appropriate balance between qualitative reasoning and quantitative rigor. With an emphasis on practical applications, this text helps undergraduates develop sound problem-solving techniques through worked-out examples and challenging end-of-chapter problem sets. Students also learn how to construct and interpret phase diagrams suitable to the problem being considered.
