Meteorites Classification

The official classification of meteorites in The Meteoritical Bulletin,  must be done through the procedures established by the Nomenclature Committee of The Meteoritical Society. According to this, the procedures entail the donation of samples (repository), the payment of the analyses that are necessary to carry out, and carry out these analyses.

The procedure requires performing different analyses, and these entail laboratory fees that need to be paid.

The Meteoritical Society says;  The minimum mass of a type specimen should be 20% of the total mass or 20 g, whichever is the lesser amount. For newly paired meteorites from dense collection areas, the minimum required mass shall be whatever is needed to bring the aggregate mass of existing type specimens (if any) to 20% of the aggregate mass of the entire pairing group or 20 g, whichever is less. Larger type specimens are recommended (...) for meteorites larger than 100 g:

Mass (to classify)         Recommended type specimen.

1 gr - 300 gr                    at least 20 % of total mass

301 to 500 gr                  at least 50 gr

501 to 1000 gr                at least 65 gr

1001 to 5000 gr              at least 100 gr

5001 to 10 kg.                 at least 250 gr

More than 10 kg             at least 500 gr



However, these larger type specimens requirements are mandatory for meteorites declared to be in Special Pairing Groups (§4.2c), and apply collectively to all new (previously unapproved) meteorites declared to be in such a group.

How long to see your meteorite officially published?

The Meteoritical Bulletin.

The Meteoritical Bulletin is the official place where meteorites are recorded ( It is the maximum guarantee of authenticity, therefore, all the meteorites that are going to be registered will go through a technical process. Once the type specimen is duly deposited, and the analyzes correctly carried out, a Nomenclature Committee will examine the information and vote in favor (or not) of the official publication. It is very important that as much information as possible is collected about the meteorite, to solidly support the request for publication. But it is not known how long this process will take. Sometimes it is done in a few weeks, and sometimes it can take years. It will depend on the review time the Nomenclature Committee needs.
