William White teaches geochemistry as a Professor of earth and atmospheric sciences at Cornell University. He received a B.A. in geology from the University of California, Berkeley and a PhD in oceanography from the University of Rhode Island. He is a fellow of the Geochemical Society/European Association of Geochemistry and the AGU, and has been named a highly cited author by ISI.
The book would also serve well as a complete geochemistryreference book for an introductory class for those students wantingextensive equations and more detailed technicalexplanations. (The Reading Geologist, 1 January2014)
