Clays in the Critical Zone

Paul A. Schroeder is a Professor in the Department of Geology at the University of Georgia. Previously he has held the positions of President of the Clay Minerals Society and co-director of the Georgia Electron Microscopy Lab. His research focuses on the study of clays and clay minerals using NMR spectroscopy, Fourier transform IR and Raman spectroscopy, radiogenic, cosmogenic and stable isotopes, chemical and thermal analyses, and X-ray and electron diffraction.

'Clays in the Critical Zone assembles an impressive amount of theory and practice from widely dispersed disciplines and important primary sources, including case studies. The result is a thorough, integrated treatment of all the ideas and methods necessary to satisfy expectations raised by the title. Professor Paul A. Schroeder's considerable experience with the methods and their applications, and with supervising student work using those methods, has prepared him well for identifying and successfully explaining many nuances of the analytical methods and interpretive approaches, and the results they produce.'
