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).
5-517: Kostovite ( IMA symbol : Ktv) is a rare orthorhombic -pyramidal gray white telluride mineral containing copper and gold with chemical formula AuCuTe 4 . It was discovered by Bulgarian mineralogist Georgi Ivanov Terziev , who named it in honor of his professor Ivan Kostov (Иван Костов) (1913–2004). In 1965 kostovite was approved as a new species by the International Mineralogical Association . The type locality

Small deposits have also been found in Kochbulak (Eastern Uzbekistan ), Commoner mine ( Zimbabwe ), Kamchatka (Russian Far East), Ashanti (Ghana), Buckeye Gulch ( Leadville , Colorado, US), Bisbee (Arizona, US), Kutemajärvi (Finland), Coranda-Hondol (Romania), Glava (Sweden), Bereznjakovskoje (Southern Urals, Russia), Moctezuma (Sonora, Mexico), Panormos Bay (Tinos Island, Greece), Guilaizhuang Mine, Tongshi complex (Linyi Prefecture, Shandong Province, China), Kalgoorlie-Boulder City , (Goldfields-Esperance region, Western Australia, Australia).

15-568: 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. The presidents of the IMA have been: The IMA Medal for Excellence in Mineralogical Research
20-504: 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
25-415: Was created in 2006. It is awarded for scientific excellence and eminence as represented by long-term outstanding scientific publication in the field of mineralogical sciences. It is one of the pre-eminent awards in mineralogical research and represents a life-time achievement award. The most active IMA commission is the Commission on New Minerals and Mineral Names (CNMMN). It was founded in 1959 to coordinate
