PDF-4/Minerals 2025
Comprehensive Mineral Collection
PDF-4/Minerals 2025 is the most comprehensive collection of mineral data in the world! Ninety-seven percent of all known mineral types, as defined by the International Mineralogical Association (IMA), are represented in the database. With 53,400+ entries, there is a wide selection of chemical variants within mineral species as shown in the collection. Our database demonstrates the benefit of having combined data from several different databases.
Due to focused editorial efforts in bibliographic searching, editorial review, and classification, the mineral collection has grown by over 30% during the last 10 years. All data are statistically analyzed, then peer-reviewed by an editorial task group of ICDD scientist members, who are also mineralogists. Minerals are classified by IMA designations of family, class and subclasses, Pearson symbols, and prototype structures. All mineralogical zeolites are similarly classified using international Zeolite Association guidelines.
