Dr. Clemens Reimann was AAG's Distinguished Lecturer in 2002. Since then, he has contributed extensively to the development of geochemical atlases at the European level, especially with the GEMAS project (http://gemas.geolba.ac.at/).

His presentation of the GEMAS approach is available here <15Mb PDF file>.
