In 2019 the 8 th international DTTG workshop on “Qualitative and quantitative analysis of clays and clay minerals” will take place from Monday February 18th to Friday February 22nd at the University of Greifswald. The workshop focuses on the needs of graduate students in the field of clay science. The workshop is also open for scientists and people working in industry who are interested in clay science. Content of the workshop, taught completely in English, will include topical lectures on theory as well as practical laboratory exercises. Clay scientists from Germany and Switzerland (listed below) will cover the most important analytical tools needed to study clay minerals. This year one of the days is focused solely on electron microscopy and one day on Rietveld modeling of XRD patterns. The other days will cover a number of other methods/topics such as FTIR, CEC, STA, chemistry of clay minerals, stable and radiogenic isotopes, and pore investigations.
