History of the IUGS History The International Union of Geological Sciences (IUGS) was founded in 1961, and formally admitted by the International Council of Scientific Unions (ICSU) on 28 September 1961. It took over activities that had previously been organized by the International Geological Congress (IGC) since its first meeting in 1878 in Paris: setting up international terminology and conventions, global correlation of specimens and strata, and coordination of mapping projects on a global scale. Since its founding, IUGS has experienced rapid growth in membership, scientific scope and expertise, setting up new task groups and commissions to address specific problems, and to endorse and exploit new methodologies such as AI. The IGCs, taking place every four years, are still an independent organizational body, but are closely linked to IUGS.

The main purpose of the International Geological Congress (IGC) is to encourage the advancement of fundamental and applied research in the Earth sciences world-wide. It is one of IUGS' flagship activities. INTERNATIONAL GEOLOGICAL CONGRESS (IGC) About Most recent IGC: Busan 2024 Next IGC: Calgary 2028

Learn more on how to become an IUGS member and what benefits this brings. Membership IUGS Membership is open to all countries or defined regions. It is organised at the national level and in some places at regional level as approved by the IUGS Council. The IUGS Adhering Organizations are typically peak professional or government bodies such as Geological Societies, National Academies of Sciences, National Geoscience Committees, National Research Foundations, Geological Surveys or Ministries. The Adhering Members hold the proper authority from those individual countries or defined geographical regions. Active Adhering Members are represented by their nominated delegates that form the IUGS Council, which is the Union's governing body. F E E S & C A T E G O R I E S Adhering members pay an annual fee according to a financial contribution unit established by the Council. The Executive Committee adjusts it based on the inflation rate. The request for payment of the annual membership fee is usually sent out by the IUGS Treasurer in the first quarter of each year, after review by the Executive Committee. Membership fees are used to support research projects and related activities of various constituent groups (Commissions, Task Groups, Initiatives, Joint Programs of the Union) by funding applications to IUGS and IGCP. Additionally, the fees are used to support several awards, including the Hutchison Fund Travel Award, the Émile Argand Award, the James M. Harrison Award, the Early Career Award, and the Scientific Awards of Excellence. B E N E F I T S Engagement in the IUGS Council's discussions and decisions concerning financial issues, strategic directions and updates of the Union constitution Voting rights in the elections for the IUGS Executive Officers and the selection of the IGC venue Representation at the International Science Council (ISC) and similar international bodies Access to educational resources, including open-access publications, educational kits, and field guides Capacity building and training, including online courses, webinars, workshops, training programs, and mentorship programs organised by IUGS and its affiliated organisations Member Benefits A P P L I C A T I O N F O R M Individual countries or multi-national regions may apply for adhering membership through their designated peak body or organisation (the Adhering Organisation). On acceptance of the application and subsequent payment of the annual subscription invoice the applicant will be admitted as a voting member. DOWNLOAD APPLICATION FORM

Episodes (Journal of International Geoscience), IUGS-GSL books. PUBLICATIONS Episodes (Journal of International Geoscience) IUGS - GSL books IUGS - International Commission on Geoheritage Books Annual Reports IUGS expects that the scientific activities funded by the Union will result in some form of publication and it has two principal avenues for such publications: The quarterly journal Episodes, which carries peer-reviewed scientific articles, news and conference reports, and other contributions. The journal is currently managed in South Korea. Books resulting from the work of IUGS bodies and from sessions held at International Geological Congresses. Since 2004 these books have been published under an agreement with the Geological Society of London (GSL). Significant results of IUGS scientific work also appear regularly in a wide variety of disciplinary journals and books published by scholarly professional societies and for-profit enterprises. From 1980 to 2001 IUGS produced its own numbered series of monographs. IUGS no longer prints, sells, or distributes monographic publications. A list of these volumes is maintained for historical purposes only.
