# International Mineralogical Association

Founded in 1958, the International Mineralogical Association (IMA) is an international group of 40 national societies. The goal is to promote the science of mineralogy and to standardize the nomenclature of the 5000 plus known mineral species. The IMA is affiliated with the International Union of Geological Sciences (IUGS).
The Association supports the activities of Commissions and Working Groups involved on certain aspects of mineralogical practice and facilitates interactions among mineralogists by sponsoring and organising meetings. In particular, the IMA holds its general meeting every four years. The last meeting was scheduled in 2022 in Lyon, France.

## Working groups and commissions

The most active IMA commission is the Commission on New Minerals and Mineral Names (CNMMN). It was founded in 1959 to coordinate the assigning of new mineral names, revision of existing names and discreditation of invalid species. Traditionally, the validation procedure of new minerals is one of the chairman's tasks and the discreditation or revalidation procedure of invalid species are two of the vice-chairman's tasks. In July 2006 a merger between the CNMMN and the Commission on Classification of Minerals (CCM), initiated at the request of both commissions, resulted in the Commission on New Minerals, Nomenclature and Classification (CNMNC).
