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 Pallasite, ungrouped means:
"A pallasite that is neither a member of the main group nor the Eagle Station grouplet, and is therefore ungrouped."
The highlighted words are defined as follows:
pallasite: A meteorite that is a mixture of metal and silicates (usually olivine grains).
ungrouped: Describes meteorites which have been well-enough characterized to determine that they do not fit into any of the established groups.
