The Met Bull


Protocol and requirements for our laboratory.

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 analyzes.

The procedure requires performing different analyzes, 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                -             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.

Welcome to Meteorites Lab

Welcome to METEORITES LAB,  for petrographic studies, and also preparation and conservation of astromaterials and geological samples (rocks, fossils, lavas, etc) for scientists and collectors, and classification of new meteorites in The Meteoritical Bulletin. Quite often I receive notifications from people who believe they have found a meteorite, and turn to me for study. For this reason, there is a Research protocol to which I can receive your samples for study and classification of astromaterials. Then I leave the information regarding this research protocol and how to proceed to submit your samples for analyses. Curation services are also offered for the preservation, documentation and preparation of samples. Uncovered thin section preparation service for the classification of meteorites and rock petrography sections for educational purposes.  AVOID LEGAL TROUBLES.   The identification of meteorites by petrographic techniques does not compromise that advanced techniques can vary
