Recommended classes in the Meteoritical Bulletin Database are assigned by the database editor. In most cases, this is based on the most recent classification that appears in either the Catalogue of Meteorites, MetBase, the US Antarctic Meteorite Newsletter, the Japanese Meteorite Newsletter, or the Meteoritical Bulletin. However, in a few cases it reflects differences of opinion about the proper way to classify the meteorite. The nomenclature used may also be modified by the editor to conform to an internally consistent classification scheme
The recommended classification Acapulcoite means:
"A primitive achondrite belonging to the acapulcoite-lodranite family."
The highlighted words are defined as follows:
primitive achondrite: A meteorite that has lost its chondritic texture due to heating and partial melting, but still has nearly chondritic composition.
acapulcoite-lodranite: Acapulcoites, named after the Acapulco, Mexico, fall of 1913, and lodranites, named after the Lodran, Pakistan, fall of 1868, are closely related, equigranular meteorites; acapulcoites are finer grained than lodranites and contain rare, relict chondrules, and there are transitional meteorites between the two types (e.g., EET 84302, GRA 95209). Mineral assemblages are similar to, but distinct from those of ordinary chondrites. Compositions are subchondritic, with lodranites showing a higher degree of fractionation.
