IMA Commission Releases Newsletter on New Minerals

In a release dated October 16 2026, the International Mineralogical Association’s Commission on New Minerals, Nomenclature and Classification published Newsletter 93, summarizing recent developments in mineral naming conventions and classification schemes¹. The document appears in volume 38 of the European Journal of Mineralogy, spanning pages 629‑633¹.

Authored by Ferdinando Bosi, Frédéric Hatert, Marco Pasero, and Stuart J. Mills, the newsletter presents updated guidelines for assigning official mineral symbols, revises criteria for distinguishing polymorphs, and introduces several newly approved mineral species identified during the past year¹. It also reviews changes to the IMA's nomenclatural rules that affect how future discoveries are evaluated and recorded¹.

The publication is part of the annual CNMNC series; Newsletter 93 follows previous editions that have addressed issues such as synonym handling, priority disputes, and the integration of new analytical techniques into classification protocols¹. By consolidating these updates, the commission aims to maintain consistency across global mineral databases and support researchers in accurately identifying specimens¹
