The International Union of Geological Sciences (IUGS) is an international non-governmental organization devoted to international cooperation in the field of geology. About The IUGS was founded in 1961 and is a Scientific Union member of the International Science Council (ISC), formerly the International Council for Science (ICSU), which it recognizes as the co-ordinating body for the international organization of science. Currently geologists from 121 countries (and regions) are represented in the IUGS. A broad range of scientific topics are covered by its commission, task groups, joint programmes and affiliated organizations. IUGS promotes and encourages the study of geological problems, especially those of worldwide significance, and supports and facilitates international and inter-disciplinary co-operation in the earth sciences. The Union's Secretariat is currently located at the Chinese Academy of Geological Sciences in Beijing, China. Activities IUGS is a joint partner with UNESCO for the International Geoscience Programme (IGCP) and also participates in the Global Geoparks Network (GGN). The Geological Society of London oversees the production and distribution of IUGS Publications. The Geological Society of India produces and distributes the Union's quarterly journal, entitled Episodes, as well as providing editorial support. Interested parties can download the latest issues of Episodes free of charge. Commissions IUGS runs seven international commissions, covering the following topics: Commission for the Management and Application of Geoscience Information (CGI) Geoscience Education, Training and Technology Transfer (COGE) Geoscience for Environmental Management (GEM) International Commission on Stratigraphy (ICS) International Commission on the History of Geological Sciences (INHIGEO) Commission on Tectonics and Structural Geology (TECTASK) Commission on Global Geochemical Baselines (CGGB) The latter commission (CGGB) is the youngest: its establishment was approved on 31 August 2016 in Cape Town at the Fourth Ordinary Session of the IUGS Council meeting. It had been a task group since 1998, with a precursor existing since 1988. International Geological Congress The International Union of Geological Sciences is the main scientific sponsor of the International Geological Congress (IGC), which takes place every four years. The first congress was in France in 1878 where a few geoscientists gathered to share new finds and the aim was to create a framework and a platform for geoscientists to meet at regular intervals. The event has been growing bigger with each congress. Brisbane hosted the 34th congress in August 2012 and Cape Town the 35th in 2016. Delhi was to host the 36th in March 2020 as a collaborative effort by
