Recommended classifications

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 Mesosiderite-B1 means:

"A mesosiderite of petrologic class B and metamorphic grade 1."

The highlighted words are defined as follows:

mesosiderite: A brecciated meteorite containing subequal silicate and metallic components; the silicates are dominantly igneous rock fragments.
