European Society for Isotope Research


The history of the ESIR starts in 1990, when during International Isotope Meeting "Three Isotopic Days" (Poland) Mariusz O. Jędrysek proposed establishment of a scientific isotope society with the aim to organize workshops on biannual basis.

The "Isotope Workshop I" was organized under the auspices of the Isotope Section of the Mineralogical Society of Poland by Stanislaw Halas and Mariusz O. Jędrysek in Lublin (Poland) in May, 1992. Over 50 participants attended the meeting; with the great majority of participants from Poland, but also from Canada, the Czech Republic, Germany, Hungary, Japan, Slovenia and Ukraine. During the Workshop participants took the decision to reorganize Isotope Section of the Mineralogical Society of Poland and to register it in accordance to accepted goals, under the name of the International Isotope Society (IIS) by a proper court in Wroclaw (Poland). As the main aim of the new Society promotion of scientific cooperation in geochemistry was indicated.  It was also agreed that the Society is to be focused in Middle Europe, the Society is open to members from anywhere in the world.

Thirteen ESIR workshops took place so far in various countries of Eastern Europe, the last one in Zadar, Croatia from 20 to 24 September 2015, where new ESIR leadership was elected.
