'[a] complete and authoritative geochemistry desk reference.' Environmental Science and Technology, 34:1 (2000) 'This Encyclopedia of Geochemistry has been painstakingly put together over a number of years, and the care and attention to detail has been very worthwhile. Here is a volume that exceptionally compiles basic information, and the details of commonly used techniques, with essays of introduction to different subject areas. Every Library should certainly have a copy, as it will be widely used by students, researchers and teachers alike. ... For all sorts of reasons, more and more people need to understand how the Earth works and this volume is a considerable resourse for those working towards that goal.' Chris J Hawkesworth, Dept. of Earth Sciences, University of Bristol, UK in Journal of Petrology, 41:12 'The Encyclopedia of Geochemistry is a "keystone" reference source, appreciated not only by all those involved in the various fields of geochemistry, but also by experts and students alike in neighbouring fields of geoscience.' Jorg Matschullat, in Environmental Geology, 39:5 (2000)
