Geochemistry - Assets

1 GeochemistryAn IntroductionIntroducing the essentials of modern Geochemistry for students across the Earth andenvironmental sciences, this new edition emphasizes the general principles of this centraldiscipline. Focusing on inorganic chemistry, Francis Albar de s refreshing approach isbrought to topics that range from measuring geological time to the understanding of climatechange. The author leads the reader through the quantitative aspects of the subject in amanner that is easy to early chapters cover the principles and methods of physics and chemistry thatunderlie Geochemistry , to build the students understanding of concepts such as isotopes,fractionation, and mixing.

2 These are then applied across many of the environments onEarth, including the solid Earth, rivers, and climate, and then extended to processes onother new chapters have been added on stable isotopes, biogeochemistry, andenvironmental Geochemistry . Student exercises are now included at the end of each chapter,with solutions available Albar deis Professor of Geochemistry at the Ecole Normale Sup rieure de Lyonand a member of the Institut Universitaire de France. He had held visiting professorshipsat universities in the USA, Australia, and Japan.
