Mission and programs · 2024

Mission

Supports the teaching of mineralogical concepts and procedures, and attempts to raise the scientific literacy of society with respect to issues involving mineralogy in the widest sense. The Society publishes journals, a magazine, and books, as well as uses short courses, workshops, lectureships, website, social media, awards, grants, symposia, and meetings for professionals, students, and the public.

Activities or mission (Part I)

The Mineralogical Society of America (the Society) was founded for the advancement of mineralogy, crystallography, geochemistry, petrology, and promotion of their uses in other sciences, industry, and the arts. The Society encourages fundamental research about natural materials.

  • Publications: Scientific publications (journals and books) and website produced for the advancement and promotion of mineralogy, crystallography, and petrology. Some examples of the publication are: American Mineralogist, subtitled in International Journal of Earth and Planetary Materials, is the print journal of the Society, and it has continuously appeared since 1916. It publishes the results of original scientific research in the fields of mineralogy, crystallography, geochemistry, and petrology with the goal of providing readers with the best in earth science research. Reviews in Mineralogy and Geochemistry - A series of multi-authored, soft-bound books containing cogent and concise reviews of the literature and advances about a subject area. There are 88 volumes published since 1974. Monographs and Textbooks - Single or limited authored, instructional textbooks. Elements - A full-color magazine first published in January 2005, Elements is the official newsletter of the Society. Published bimonthly, each issue also contains several thematic scientific articles written for a broad audience. Handbook of Mineralogy - A definitive modern source for data on all mineral specials. The authors of the handbook, John W. Anthony, Richard A. Bideaux, Kenneth W. Bladh, and Monte C. Nichols have made the volumes and full text of the five volumes available to MSA to keep updated and available in print and electronic forms.

Kraus Crystallographic Research Fund and grants for student research in mineralogy and petrology are given each year based on the quality, innovativeness, and scientific significance of the research proposed by students and young researchers. Committees of the Society members evaluate the written proposals and recommend one Kraus and two mineralogy and petrology awards to be made to the Society's council, who finally approve the selection.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 11 November 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
