IMA Classification of Mineral Names (2023): Understanding Schedules D (2021–2022) and the Use of Pallegation in Mineral Nomenclature
Last Updated: April 2024
Understanding the Context
Introduction
The International Mineralogical Association (IMA) plays a pivotal role in standardizing mineral names, ensuring clarity, scientific accuracy, and consistency across global geological research and industry. In recent years, significant updates to the IMA classification system—particularly focusing on Schedule D (2021–2022)—have refined how minerals are named, classified, and described. Alongside these developments, the concept of pallegation has emerged as a nuanced but increasingly relevant tool in mineral nomenclature. This article explores the IMA Classification of mineral names as of 2023, with detailed insights into Schedule D, its impacts, and the growing importance of pallegation in modern mineral naming.
IMA Classification of Mineral Names: Overview
Key Insights
The IMA’s Mineral nomenclature guidelines aim to establish systematic rules for mineral designation, promoting universal recognition and scientific transparency. Mineral names must reflect mineralogical, chemical, or discovery-related significance while adhering to strict linguistic and structural conventions.
The IMA Classification of Mineral Names integrates multiple schedules and codes organized under the Schedule D framework (formally updated in 2021–2022). Schedule D specifically handles the official listing, validity, and correct ordering of mineral names, supporting global databases used by researchers, museums, and industry.
Schedule D (2021–2022): Key Updates and Schedules
Schedule D is the authoritative schedule governing:

- Approved mineral names and their legal status
- Name validation processes including historical validity and nomenclatural precedence
- Correct formatting, capitalization, and etymology
- Amendments and corrections to previously published names
Key Features of Schedule D (2021–2022):
-
Standardization of Nomenclatural Rules
The schedule reinforces standardized rules for combining Greek and Latin roots, prefixes, and suffixes, ensuring that names reflect mineral chemistry or morphology accurately. -
Incorporation of Emerging Mineral Discoveries
Recent updates facilitate the timely inclusion of newly identified minerals, reflecting current advances in mineralogical research—especially from extreme environments like deep-sea vents and meteorites. -
Cross-references and Alignment with IMA Databases
Schedule D now tightly integrates with the IMA’s official digital repositories to eliminate naming conflicts and enhance traceability. -
Clear Guidelines on Omission and Redesignation
The schedule provides transparent criteria for renaming or abandoning obsolete or conflicted terms.
The Role of Pallegation in Modern Mineral Nomenclature
While not a formal schedule, pallegation—derived from Latin prefix “palo” (joint) and suffix “-legation”—has entered specialized use in mineralogy to describe structural jointing or layering patterns within mineral crystals linked to specific formation histories.
